Tips for Best Results

  1. Use WebP for web: WebP is 25-35% smaller than JPG at the same quality
  2. Use PNG for transparency: Only PNG and WebP support transparency
  3. Use JPG for photos: Best compression-to-quality ratio for photographs
  4. Keep originals: Always keep your source files in case you need to reconvert

Frequently Asked Questions

How many images can I convert at once?

Can I resize images during conversion?

The batch converter focuses on format conversion. For batch resizing, use Resize Image with multiple files.
