Examples

Convert all HEIC files to JPG with maximum compression (smallest file size):

heic2img /path/to/heic/files -q 50

Convert to WebP format (often provides better compression than JPG):

heic2img /path/to/heic/files -f webp -q 60

Resize images to a maximum of 1200 pixels (width or height) while converting:

heic2img /path/to/heic/files -m 1200

Set a custom maximum file size (e.g., 1MB):

heic2img /path/to/heic/files --max-file-size 1.0

Convert to a different directory:

heic2img /path/to/heic/files -o /path/to/output

Convert and delete original HEIC files and associated MP4 files:

heic2img /path/to/heic/files --delete-originals

Tips for Smallest File Size

For platforms like Facebook Marketplace or Craigslist where image quality isn't critical:

1. Use WebP format for best compression: -f webp
2. Lower the quality setting: -q 50 (or even lower if acceptable)
3. Resize large images: -m 1200 (or smaller if acceptable)
4. Set a strict file size limit: --max-file-size 1.0 (for 1MB maximum)

Example for maximum compression:

heic2img /path/to/heic/files -f webp -q 40 -m 1000 --max-file-size 1.0
