- Select Multiple Files: Hold Ctrl or Cmd to pick up to 20 images at once.
- Choose Format: Select WebP, JPG, PNG, or AVIF.
- Convert & Download: Click convert and grab your files as a single ZIP archive.
🔒 Privacy First:
None of your images ever leave your device. We use WebAssembly to process everything 100% locally in your browser.
