Batch crop photos to preset dimensions

To batch crop photos to preset dimensions, you have several options depending on your preferred platform (Windows, macOS, or online), and whether you prefer GUI tools or command-line automation. Here’s a concise guide for each method:

1. Using Free Software (GUI-Based)

Windows/Mac: IrfanView (Windows only)

• Steps:

  1. Download and install IrfanView and IrfanView Plugins.

  2. Go to File > Batch Conversion/Rename.

  3. Add all images to the input list.

  4. Select Advanced and enable Crop.

  5. Set the X/Y position and width/height to your preset dimensions.

  6. Start batch.

macOS: Preview + Automator

• Steps:

  1. Use Automator to create a custom workflow.

  2. Add action Get Specified Finder Items.

  3. Add Crop Images action (requires scripting or 3rd party tools like ImageMagick).

  4. Save and run the workflow to crop.

2. Using Online Tools

(Use when you don’t want to install software.)

• Tools: https://bulkresizephotos.com/, https://www.birme.net/

• Steps:

  1. Upload all images.

  2. Set cropping area (top-left/center).

  3. Set exact width and height (e.g., 800×600).

  4. Export/download all at once.

3. Using Command-Line: ImageMagick (Cross-platform)

Install ImageMagick

• Windows/Mac/Linux: https://imagemagick.org

Batch Crop Command

bash
CopyEdit
magick mogrify -path output_folder -crop 800x600+0+0 -gravity Center *.jpg

• 800x600 = target size

• +0+0 = crop offset (change if needed)

• -gravity Center = centers the crop

• output_folder = folder for results

4. Photoshop (Batch with Actions + Image Processor)

• Create a new Action that crops to your preset size.

• Use File > Scripts > Image Processor or File > Automate > Batch.

• Apply your cropping Action to an entire folder.
