FAQ

Q: How does Smart Cropping work?

A: Smart Cropping uses Apple's Vision framework to identify the most important part of each image and centers the crop around this area, ensuring the main subject remains in frame.

Q: Can I process RAW image files?

A: Yes, Bulk Cropper supports most common RAW formats, converting them to your selected output format.

Q: How do I create multiple sizes from the same image?

A: Add multiple dimension presets in the Dimensions tab. Each image will be processed according to all presets you've defined.

Q: Is there a limit to how many images I can process at once?

A: There's no built-in limit, but processing very large numbers of images (1000+) may require more time and system resources.

Q: Can I cancel a processing job once it's started?

A: Yes, you can click the "Cancel" button during processing to stop the operation.

Troubleshooting

Application Won't Open

  • Verify you're running a compatible macOS version (12.0+)
  • Try restarting your Mac
  • Check if the app needs to be updated

Images Not Processing

  • Ensure input files are valid image formats
  • Verify you have read/write permissions for the input/output folders
  • Check that dimensions entered are valid numbers

Poor Quality Output

  • Increase the quality slider for better results (especially for JPEG/HEIC)
  • Consider using PNG format for graphics requiring transparency
  • Larger dimensions require higher quality settings to maintain clarity

App Seems Slow

  • Processing large batches of high-resolution images requires significant resources
  • Close other resource-intensive applications
  • Consider processing in smaller batches
