When working with multiple images, cropping them all individually to exactly the same size can be very painful. Or maybe your images need a watermark, but you need to edit 30 batches. If you edit them all at the same time, you can save a lot of time and energy. Learn how to edit multiple photos to make photo editing more efficient.
Windows, MacOS and Chrome OS are covered in this guide. All three platforms have native tools that make it easy to edit your photos and pictures. However, there is no native way to edit more than one image at a time. That means we have to turn to third-party solutions.
While there are many paid applications that like to exchange your money for batch processing, we focus on powerful free software.
Batch processing in Windows
For Windows we use an open source Photoshop replacement and a plugin:
GNU Image Manipulation Program (GIMP) – The biggest threat to Adobe Photoshop is this free, open source desktop program. It contains almost everything you need to edit images, e.g. B. crop, color match, add effects, layers, and more. We strongly recommend this software if you want to avoid Photoshop's monthly subscription.
Batch Image Manipulation Program (BIMP) – This is a free plugin for GIMP that adds batch editing to the open source desktop software. You need to install GIMP first, followed by this tool.
Once you've installed both tools, you can use them to edit multiple images at the same time.
Step 1: Open GIMP and click on File in the main menu.
Step 2: Select Batch Image Manipulation from the dropdown menu.
Step 3: A popup window will appear. Under Manipulation Set, click the Add button.
Step 4: Select a manipulation from the pop-up menu that appears.
The next window that you see depends on the manipulation you have chosen. Here they are at a glance:
- Change size – Change the height and width in percent or pixels. You can also use a stretch, keep, or filled aspect ratio and change the interpolation. You can also change the image's X and Y DPI settings.
- Harvest – You can use a standard aspect ratio, a manually set aspect ratio in pixels, and a starting point: center, top left, top right, bottom left, or bottom right.
- Rotate or rotate – Rotate your pictures horizontally or vertically, or rotate 90, 180, or 270 degrees.
- Color correction – Adjust the brightness and / or contrast, convert to grayscale, or use automatic color level correction. You can also change the color curve using a settings file saved on your PC.
- Sharp or blurry – Move a slider left (add focus) or right (more blur).
- Add a watermark – You can apply a text-based watermark that you enter in the window or select an image saved on your PC. You can also set the opacity and position of the watermark.
- Change format and compression – Convert your image to one of 10 formats, including JPEG, GIF, and TGA. There is also a quality regulator from 0 to 100.
- Rename with a pattern – Enter characters to keep the original file name without extension, use incremental numbers, or use the recorded date and time.
- Other GIMP procedure – Choose from a list provided by GIMP, e.g. B. Posterize, Bump Map, Blur and much more.
Click the OK button for each manipulation window so that it is saved in the current manipulation set.
Step 5: Click the Add button again if you want to add another manipulation to the set as shown above.
Step 6: Under Input files and options, click the Add images button and select the images you want to edit in bulk.
Step 7: Choose an output folder.
Step 8: Click Apply to start the batch process.
Batch processing in MacOS
While you can install GIMP on MacOS, there is no version of the BIMP plugin for the Apple platform. Instead, you can contact PhotoScape X in the Mac App Store. There are two batch processing functions that are blocked behind a "Pro" paywall. However, the basic needs such as cropping and resizing remain free. The problem is that the overall user interface is a bit chunky, especially if you rely heavily on GIMP.
Step 1: With PhotoScape X open, click Stack on the menu.
Step 2: Click the blue plus sign to the left of Add Folder to load the folder with your pictures.
Step 3: Your picture gallery will be loaded in the lower left window. Drag the images you want to edit into the upper middle window.
Step 4: Select the manipulator on the right that you want to apply to the images. As with the GIMP plugin, you can apply multiple image manipulators before exporting the changed images.
Here are the available manipulators at a glance:
- Harvest – Click the up and down arrows to expand or expand each page based on the center of the image.
- Change size – Change the width and / or height in pixels, change the aspect ratio, widen or shorten the edges, or enter a custom size.
- Colour – Here you have many options, e.g. B. the use of automatic layers, contrasts or colors. Lighten or darken; Adding HDR; Adjusting the clarity; Change the total temperature and more.
- Filter – Here you can add film grain, vignette and bloom or sharpen the images. Other options include reducing color and luminance noise.
- Movie – Add up to six effects from the app's huge library, which includes film, duotones, overlays, old photos, dirt and scratches, and textures. However, some of them are blocked behind the "Pro" Paywall.
- Light – As with film, you can add up to six effects from the app's huge library, which includes Light Leaks and Lens Flares.
- Insert – Add up to six insertions: stickers, images, pictures, filters and text.
Step 5: Click the Save button to export your modified images.
Batch editing in Chrome OS
Google's operating system looks different. Since this depends heavily on the web, it is currently almost impossible to obtain a tool that can be used to edit images in groups. Chrome OS supports Linux, but installing the Linux-based version of GIMP and the BIMP plugin may not be worth the time unless you're an experienced Chromebook owner. The BIMP plugin doesn't even have an installer. So you have to download the source files and install them via the terminal.
Other web-based and Android apps can include batch editing, but throw the functionality behind a paywall. These include Polarr Photo Editor, Lightroom, Photoshop Express and Pixlr. Paid solutions are likely to process batch exports such as the GIMP plugin and PhotoScape X.
