6 Free Batch Image Editors for Windows, macOS and Linux – It is often important to play out a similar arrangement of operations on different pictures. For example, you might need to convert a set of PNG images to JPEG, or vice-versa. Maybe you have a bundle of high-determination pictures from your DSLR that you have to resize to a sensible size for sharing on the web. It is also important to strip photos of private EXIF data such as the date, time, model and the GPS location of the photo before sharing them on the internet, as this is a big privacy concern. While doing these assignments is basic and clear when we have two or three pictures, it turns into an activity in disappointment when we have, say, 50, or even 200 such pictures. Batch Image Editing software makes it easy to apply the same operations to multiple images and save us time and effort. So, in this article, we will list the best free bunch picture editors on Windows, Linux and macOS.

We tested all the software on the exact same set of images. We took 6 images, 4 from our DSLR, 1 from a Lenovo smartphone, and the last image downloaded from the internet. We applied the following operations on them:

• Convertthe JPEG images to PNG format.
• Resizeevery image to a maximum width of 640px, and let the software adjust the height accordingly, keeping the aspect ratio.
• Removeall possible EXIF data.
• Explore other optionssuch as automatic renaming of the converted images, effects etc.

Then, we ranked the software according to a variety of factors: cross-platform availability, ease of use, number of steps required, versatility, stability and performance. The results are as follows:

 1. XnConvert:

 XnConvert is an effective and thorough Batch Image Processor and our software of choice for power users who need to routinely change over, resize and compress multiple images. The software itself is quick and acceptably simple to utilize, considering the abundance of alternative it offers.

Apart from the basics, it offers alternatives to adjust color balance, lets you crop, rotate, blur, sharpen, and include numerous different impacts. There is also a Before / After preview that lets you review the changes that you are about to make to your images.

For the output images, XnView gives you the alternative of overwriting existing records (if you are not changing the file format), set up filename patterns, compression levels, and delete the originals after the conversion is complete. There is even a check box to automatically open the goal organizer a while later. Convenient!

XnView passed our test with flying colors as it gets everything right – it is cross platform, and intuitively let us resize, compress and remove EXIF data from our photos. Above all, it is not complicated to use despite the myriad features it offers. Highly recommended.

2. Converseen:

Converseen is a basic batch image processing tool for Windows and Linux. While it doesn’t coordinate to the sheer number of components that XnView offers, it is as yet a basic and quick apparatus that does the employment. The workflow is as follows : You select (Import) the pictures you wish to change over, select Check All, pick the amount you need to resize the pictures, and select the organization and quality. There are options to maintain aspect ratio, choose the directory in which you want to save the converted images, and flip or rotate the images.

As simple as the tool is, there are a few confusing elements in the interface. For example, the screen where you select the nature of yield pictures, there is an alternative to pick both the info and yield organization’s quality, when we just need to change the output format’s quality.

It also automatically removes EXIF data without prompting. While we needed to dispose of this information in our test, there should have been an option to preserve it, if needed. Choose this tool if you only need basic options for conversion and do not mind getting rid of EXIF data in all your images.

3. IrfanView:

Not only is IrfanView a great image viewer for Windows, it surprisingly packs in a number of image editing capabilities as well. Basically, explore to File > Batch Conversion/Rename, and you’re ready.

Basic conversion, setting output image quality, and pattern renaming are simple affairs. To get to more capacities, you need to go into the Advanced settings. This screen offers a completely gigantic number of alternatives, which is uplifting news for the power user. The settings include resizing, cropping, flipping, adding watermarks or overlay text to images, changing color depth, and much more.

On the other side, the enormous number of choices is also its biggest downfall due to just how jumbled and confusing the interface is. As a saving grace however, there are options to Save and Load the options you have set up, which makes future conversion jobs much easier. IrfanView gains points in offering a lot of options, and being an awesome picture watcher as a reward, yet loses some in being less easy to understand and confined to Windows.

4. Bulk Resize Photos:

This is a unique tool in the list, since unlike the others, it is a web application. It is also unique among web apps, as no uploading to any servers takes place. There is nothing to install, and no sign-in or registration.

The tool is rather basic and straightforward: Choose a list of images, pick the size you need in pixels or rate, select the yield organize, and you’re ready. It will change over as well as resize your pictures, strip them of EXIF data, and ask to store them as a zip file in your Downloads folder. Not a lot of choice, which is bad for the power user, but great for the causal user. It additionally incorporates a choice to add a watermark to your pictures, which is a pleasant touch.

5. Bulk Image Manager:

Bulk Image Manager is a basic Windows-only application for batch image editing. It is a portable app, which implies that it doesn’t require installation. Usage is simple enough – select the images, the output folder, output file names, resize parameters (pixels or percentage), and output format. It automatically preserves aspect ratio, and removes EXIF data.

There are no choices to determine the quality, or any other basic or advanced features. There is a progress bar, but the user receives no notification once the job is completed. Despite the lack of polish, the portable and lightweight nature of this program makes it suited for irregular occupations.

6. ImageMagick:

ImageMagick is a command-line photo-editing tool for Linux, Windows and macOS.  It is not perfect for the easygoing user, but rather is completely otherworldly in the hands of an accomplished console warrior. Batch image conversion is just one of the features out of its absolutely humongous feature-set. To do our test, we utilized the accompanying charges in our pictures envelope:

1. mkdir converted_from_imagemagick

2. convert '*.jpg' -resize 640x640 .\converted_from_imagemagick\%03d_converted.png

The mkdir command creates a subfolder called ‘converted_from_imagemagick’ in the current folder. Next, we instruct ImageMagick’s convert command to resize all files with the extension ‘.jpg’ in the current folder to 640×640, convert them to PNG, and put the resulting files in the subfolder we previously created.

Note that while we instructed ImageMagick to resize the images to 640×640, it is smart enough to preserve the aspect ratio of the images and modify the image heights accordingly.
