GIMP, a free and open-source image editor, offers powerful ways to edit multiple images at once. Batch editing in GIMP is a productivity booster that helps you maintain brand consistency with ease.

How to edit multiple images at once in GIMP (Built-in tools)

Although GIMP is powerful, itself doesn’t include a full batch editor by default. However, it fully supports extensions, plugins, and scripting, which provide all the tools needed to batch edit images effortlessly.

Let’s explore them.

Way 1. Using the BIMP plugin for batch editing

You need to install the BIMP (Batch Image Manipulation Plugin) to realize batch editing in GIMP according to the following steps

With BIMP, you can batch:

• Resize images
• Crop or rotate
• Adjust brightness/contrast
• Convert file formats
• Apply color correction
• Add watermarks
• Rename files

✨How to download and install BIMP:
1. Visit the GIMP plugin registry to download BIMP.
2. Place the file in the GIMP plugin directory.
3. Restart GIMP and you will find the batch processing option in the menu.

Steps to edit multiple images at once in GIMP using BIMP plugin

1. After starting GIMP, navigate to File > Batch Image Manipulation. Open the BIMP interface. This is the command center for your gimp batch edit images operations.

2. Click Add Images to select all the files you want to process.

3. Then click Add to select the processing steps you want to apply, such as:

• Resizing and Scaling
• Rotate and flip
• Color Adjustment
• Add watermark or text
• Format conversion (JPEG, PNG, etc.)

✏Tips: Pay attention to the impact of the order of operations on the final effect (such as resizing before adding a watermark)

4. Set the output folder and file naming rules. BIMP allows you to keep the original files and avoid accidental overwriting, which is a safe best practice when how to edit multiple photos in gimp.

5. Click Apply to start processing. The progress bar will show the processing status, and the processing time depends on the number and complexity of the images.

Way 2. Automating edits using GIMP Script-Fu

For more advanced users, Script-Fu, GIMP’s built-in scripting system, offers deep control and automation. It allows you to write custom scripts to perform complex, multi-step editing tasks across large batches of images.

1. Open GIMP, to enable Script-Fu, first go to Filters > Script-Fu > Console.

2. Open a plain text editor (Notepad, Notepad++, VS Code, etc.). Create a new .scm file (example: batch_resize.scm). Paste a simple Script-Fu template:

(define (batch-resize-images pattern width height keep-aspect)
(let* ((filelist (cadr (file-glob pattern 1))))
(while (not (null? filelist))
(let* ((filename (car filelist))
(image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
(drawable (car (gimp-image-get-active-layer image)))
(original-width (car (gimp-image-width image)))
(original-height (car (gimp-image-height image)))
(new-width width)
(new-height height))
 
; Calculate proportional height if aspect ratio should be kept
(if (= keep-aspect TRUE)
(begin
(set! new-height (* original-height (/ width original-width)))
)
)
 
; Perform the resize
(gimp-image-scale image new-width new-height)
 
; Save the image (overwrites original - use with caution!)
; For safer operation, uncomment the next line to save as new file
; (gimp-file-save RUN-NONINTERACTIVE image drawable
; (string-append "resized_" filename) (string-append "resized_" filename))
 
(gimp-file-save RUN-NONINTERACTIVE image drawable filename filename)
(gimp-image-delete image)
)
(set! filelist (cdr filelist))
)
)
)
 
; Register the script in GIMP menu
(script-fu-register
"batch-resize-images"
"Batch Resize Images..."
"Resize multiple images to specified dimensions. Use wildcards (*.jpg, *.png) in pattern."
"Your Name"
"Copyright 2025"
"October 2025"
""
SF-STRING "File pattern (e.g., /path/to/images/*.jpg)" "/home/user/images/*.jpg"
SF-VALUE "Width (pixels)" "1200"
SF-VALUE "Height (pixels)" "800"
SF-TOGGLE "Keep aspect ratio?" TRUE
)
 
(script-fu-menu-register "batch-resize-images" "/Filters/Batch Tools")

3. Save the file as .scm. Put it inside your GIMP scripts folder

Windows:

• C:\Users\\AppData\Roaming\GIMP\2.10\scripts

macOS:

• /Users//Library/Application Support/GIMP/2.10/scripts

Linux:

• /home//.config/GIMP/2.10/scripts

4. Restart GIMP or run Filters > Script-Fu > Refresh Scripts.

5. Navigate to Filters > Batch Tools > Batch Resize Images. Then enter parameters and click OK.
