A small image converter for your everyday tasks. It runs in your browser, converts and compresses images quickly and easily, supports batch processing, and processes data locally without uploading files to a server.
Simple and easy to use, every day.
What Formate can do
- Batch convert images to PNG, JPEG, WebP and AVIF.
- Set width and height, preserve aspect ratio, and use Fit inside, Fill or Stretch modes.
- Adjust JPEG, WebP and AVIF quality, and choose a background color for JPEG.
- Rename files with a shared name, separator and numbering.
- Download individual results or a ZIP archive.
Processing on your device
Images are processed locally in your browser. Their contents are not uploaded to a server for conversion. The queue and results stay in the current session’s memory; refreshing the page clears them.
