How to reduce multiple photos at once photoshop. Batch photo resizer. When there is more than one

Working with a large number of photos, quite often there is a need for batch processing!
One example of such batch processing is the need to resize multiple images at once. In this article I will tell you how to do this using the program - XnView.

For example, we have a specific situation: we need to send a certain number of photos by mail or upload them to social media(any other service), where there is a limit on the size of the uploaded file. We won't manually resize each image, will we? That's right, because for this there are special programs, one of which we will analyze today. Viewer and editor graphic files — XnView. By the way, I wrote about how to quickly resize an image in the article "". I recommend to read.

The program has a simple, intuitive and user-friendly interface, high speed. To get started and run (version).

This is what the program window looks like; on the left → all folders and files of the system, on the top → toolbar. In this case, we are interested in the "Transform" tool.

1. Using the key combination Ctrl + O, open the folder with the files that we will edit.

2. Now our files are in the program window → press Ctrl + A (select all files) → and click on the “Transform” tool.

3. A new window "Batch Processing" will appear in front of us. Here you need to specify the folder where to save the images after processing and click the tab → "conversion".

4. In the left column, select the desired processing option. In this case, it's Resizing. Next, the add button becomes active → click add. Now that the Resize tool is selected in the right window of the program, we set the parameters.

Transformation parameters can be set arbitrarily (by specifying the width and height yourself), or left to the program to do this as a percentage. By choosing, for example, 25%, you will receive this percentage from the original. I leave the “Keep proportions” parameter as it is, but I uncheck the “change height with width” item.

5. After the settings have been made, click → "Run" and start the process. When the process is terminated, open the target folder and check the result.

On the first screen, the result before batch processing; on the second → after

Good day, dear friends, acquaintances, readers, admirers and other personalities.

Digital camera, mobile phone with a camera, or something else that can take photos, is now in almost every home. In this connection, a fairly substantial amount of pictures, images and other picture-differences sometimes accumulate on a computer, which take up a substantial amount of space on the hard disk ( ;)).

In connection with the foregoing, I will share with you the most valuable program that I found on the Internet, which will help you significantly simplify the processing process, reduce the weight of photos and images without much loss in quality, and also make it possible, say, to quickly do with a large number of pictures of various "fineness" (for example, highlight with a frame or put your signature in the corner) or convert them to the format you need.

Let's get started.

FastStone Photo Resizer, is a mass processing program for photos and images

As you already understood from the title, the program is called "FastStone Photo Resizer" and is engaged in recompressing, lightening, signing, changing the format, adding a frame and doing other wonders with your photos, not individually, but with all selected at once.

It is completely free, nimble and its only drawback (if it can be considered a drawback) is the English language. However, users in need may find a crack on the Internet, but for now I'll tell you how to work with this happiness without any unnecessary installations and conjectures;)

The installation is extremely simple and I will not dwell on it (just run the file and click on the "Next") button, and therefore let's move on to setting up and using it.

To get started, using the good old Windows Explorer, take a few images and copy them to some folder. We will work with them, so to speak, in test mode, so that you understand what's what.

As a matter of fact, on the left, in the window thereof, you can select a folder on the disk (to do this, click on the button with the image of three dots) where you have the images with which you will work. Select the folder with images that you prepared in advance (above in the text of the article).

If you did everything correctly, now you can select specific images in the list with which you will work and, by pressing the "Add" button, move the desired photo from the folder to the right window, i.e. to the window containing the list of photos to be edited.

You can select multiple photos by holding down the "Ctrl" (one by one) or "Shift" (list) key and clicking on the photo name. You can remove photos from the right list by highlighting their name and pressing the "Remove" button. Transfer everything at once by pressing the "Add all" button.

The "Output Format" column allows you to select the format in which the photos will be after editing. That is, if you need, for example, to change the resolution from .bmp to .jpg , then set "JPEG Format (*.jpg)" in this field. Next to this line there is also a "Settings" button, which will allow you to set optimization settings (quality, compression method, etc.) in order to save the maximum amount of space after converting / optimizing photos / images:

The "Output Folder" column allows you to select the folder where the program will save the photos after editing. Specify a folder using the "Browse" button.

The "Advanced Options" button allows you to set the photo editing settings (pictures or whatever you have):

Let's take a closer look at what's what, so that you have an understanding:

The first tab, called "Rezise", allows you to set the size of your photos in pixels. It is optimal to choose something like 1280 x 1024 , because it is unlikely that if you are not going to print these pictures, you need a higher resolution. Just in case, check the box Do not resize when original size is less than the new one", which will tell the program that it is not necessary to change the resolution if the file has a resolution lower (and not higher) than the specified one (that is, so that the photo does not stretch);
The second tab, "Rotate", allows you to flip photos horizontally or vertically, or rotate them by "90-0180% : If you need it, then check the "Flip / Rotate" checkbox, and then either the "Flip Horizontally" or "Flip Vertically" or "Rotate" checkbox;
The "Crop" tab allows you to crop photos. I do not recommend using it, because in streaming mode you can cut it off, which will be a shame later;
The "Canvas" tab allows you to add .. mmm .. something like margins / background, but why this is needed, I personally don’t understand, because there are frame settings around the photo for this;
"Color Depth", "Adjustments" and "DPI". The first one allows you to cut the color palette, which, from the point of view of optimizing the file weight, can be very useful, but from the point of view of quality, it can lead to sad consequences;
"Adjustments" allows you to change a bunch of goodies in-line, like brightness, contrast, gamma, and more:

I would not recommend using it, because each photo must have its own parameters and massively reshape them, without looking at what happens - this is a rather controversial decision;
"DPI" allows you to set the number of dots per inch, which is useful when printing and often not needed in our case;
The "Text" tab allows you to caption photos with text. One of my favorite options as a photographer, with which you can put, say, a tag on photos or the date of shooting:
This is done very simply: enter the text in the upper right corner, then use the "Font" button to select the font, font size, etc. Next, set, if necessary, with the "Shadow" and "Background" checkboxes the background, the shadow and their (background and shadow) colors (the "Round" checkbox can round off the corners of the background), and the transparency of the inscription with the "Opacity" slider;
And finally, using the mouse or the "Position" option, we set where this very inscription will be located: You can make a preview (by the way, of any changes that we set in the program) and see how our inscription will look using the button with a leaflet and a magnifying glass;
The penultimate tab, called "Watermark", allows you to protect your photos with the so-called watermark, that is, stick an image, say, of a logo:
This is done by selecting, in fact, the image using the button with three dots and, again, by setting all sorts of options such as transparency, shadow, position, etc., which I described above;
Well, the last tab, "Border", will allow you to create a frame for your photos, and even, if necessary, so to speak, multifaceted:
The setting is generally simple - just check the number of frame strips ("Frame 1-2-3"), set their thickness ("Width" parameter) and color ("Color" parameter) and, using the preview button, bring it to his ideal.

Having finished all the settings, click the "OK" button and, returning to the program window, once again making sure that you have set everything you need, feel free to click on " Convert".

Then all that remains is to wait for the conversion process, enjoying the numbers that indicate how much space is saved from each photo (the last column, which is called "Save (KB)"), and then go to the folder that you set as the save location ("Output Folder") and look at the result.

Everything on the sim. Let's move on to the afterword.

Afterword

Here is such a tool for mass photo processing and rescue free space(I must say that sometimes you can save whole gigabytes), and just a useful thing.

You also need to remember about loading the page on devices using Mobile Internet, the speed of which is low, and too heavy photographs slow down this process even more;
Size restrictions - social networks and various sites set limits on the size of uploaded photos - this is necessary for their normal functioning;
Original size - photos that take up a lot of space on storage media are actually several times larger than the one in which they are displayed on the screen, which causes various incidents with downloading to / from the Internet.

It remains only to save the resulting image. Below is the result of the manipulations:

How to compress photos to send via e-mail Or just for posting on the Internet? As mentioned above, before sending, you need to reduce the weight of the images. When performing compression, it is advisable to adhere to the following rules:

The weight of the image should not exceed 100 KB, and the size should be 800 by 600 pixels - this is due to the fact that there are still monitors that do not get along well with giant pictures;
If you reduce the weight of a photo, marks may appear on it, indicating that it has been compressed. To hide this, you need to blur the photo a bit using the Blur tool in Photoshop, setting the value to 0.1 - this will be enough;
It is best to save images in JPEG format.

Compressing a lot

How to compress many photos at once online? To solve this problem, there are specialized services, such as Kraken.io. At one time, this service allows you to process a large number of photos, but their total weight cannot exceed 10 megabytes.

For better photo processing, it is better to use applications that are installed on your computer. An example of such a program is Picture Combine - this graphic editor allows you to batch optimize photos. The program is easy to use, so anyone can master it:

How to compress multiple photos in photoshop

Photoshop also has the ability to compress multiple photos at once. To do this, you need to create an action - an action algorithm for batch processing photos.

The steps for creating such an algorithm are described below:

Create two folders. First save the images you want to reduce. The second will save already processed photos;
Next, you can start writing the photo processing algorithm. In the Window menu ( Window) you need to click on the item " Creating a new operation» ( Create new action), enter a name for the new action and click on "OK";
Recording of actions will begin after clicking on the button "Start Recording" ( Degin recording);
To reduce a photo, you need to open a file from the folder in which the images for processing are stored (File -> Open) (File -> open). In the "Picture" menu ( Image) choose " Image size» ( image size) - the extension and size settings window will open. After making changes, you must click on " OK». You can now save the thumbnail image to an empty folder using the Save As command ( Save as);
Next, you need to stop recording the algorithm by clicking on " Stop Recording» ( Stop recording);
For automated processing of the rest of the photos in the File menu, select " Automation»( Automates). Inside this menu, use the function " batch processing» ( Batch);
To process the entire folder at once, it is necessary in the " Source" menu ( Source) select "Folder" ( Folder), then click on "Select" ( choose) and specify a folder with photos. You also need to determine where the processed photos should be sent, for this, in " Location»( Destination) select "Folder" ( Folder) and using "Select" ( choose) specify the created empty folder. To fully automate the process, you must activate the item " Overwrite, Save command as» ( Override action “Save As” commands), otherwise you will need to approve the save path for each individual photo. To start processing, you must click " Ok».

how to reduce image size in photoshop

The number of pixels per inch is one measure of image quality. You can reduce their number different ways, but this does not affect the image quality in the best way.

You will need

- graphics editor.

Instruction

Open the image in which you want to reduce the number of pixels using an advanced graphics editor. Select image resizing in the editing functions and choose a smaller value in pixel format.

Please note that reducing the number of pixels graphic image leads to loss of quality. It is best to save the picture separately at its original size, as it is not possible to improve the image quality by increasing the number of pixels.

If you need to reduce the size of an image to a certain size while maintaining quality, open it through Paint program, which is the standard tool operating system Windows. Next, save a copy of the image and check if its size has changed. In this case, Paint simply erases from the file Additional information about him, which occupied a certain proportion in its total size.

In the case when you need to change the number of pixels down without changing the image size, use the compression function in graphic editors. note that this action will lead to loss of quality, but will reduce the size of the file itself. It is also not recommended in this case to have only one copy of the image, since it will be impossible to restore it.

Hi all. Today I decided to tell my readers about how to resize multiple images at once. I think you all know that I recently changed the design on my blog and the images that were inserted due to different sizes did not fit into it. Manually changing the pictures in each post is a hell of a job, so I decided to find a way to resize photos and images for several files at once.

And I found it. It turns out that you don't need to be a professional photo editor or anything to resize multiple images. You just need to focus and read my instructions, according to which you can resize several images.

I have been searching for several days for different programs in order to complete this task. I rummaged through a huge number of sites, but in the end I came anyway to one tool - Photoshop. It's like with shoes, I was looking for a normal store for a very long time, until I came across anabell-shoes.com.ua.

Yes, Photoshop is a very powerful tool, I like it - after all, someone does not know what it is for at all. However, in addition to processing, you can do other useful things in it. Well, for example, resize several images.

To do this, save all your images in one folder on your computer. For example, on the desktop. Next - launch Photoshop and select "File" - "Scripts" - "Image Processor" in the top menu, as shown in the screenshot below:

Now we select the folder we need, set the image quality and specify the size that we need.

We press the execute button. Everything is ready - all images are the same size. Good luck to you 😉
