Compress AVIF Online Free
How to finish the file
- 01
Open FastEdit
Go to app.fastedit.net. The editor runs locally in your browser using WebAssembly, no installation needed.
- 02
Load your image
Drag and drop your image onto the editor. FastEdit accepts AVIF as both input and output, plus JPEG, PNG, WebP, and other formats. Nothing is uploaded.
- 03
Select AVIF as the output format
Choose AVIF from the format menu. AVIF uses the AV1 codec for images, delivering the best compression ratio of any widely supported format.
- 04
Adjust quality settings
Set the quality level. AVIF at quality 60-70 typically matches JPEG at quality 85+ visually while being half the file size. Use fit-to-size for precise control.
- 05
Export your compressed AVIF
Compare original and compressed versions side by side, then export. Note that AVIF encoding is slower than JPEG or WebP, but the file size savings are worth it.
Benefits
- AVIF achieves up to 50% smaller files than JPEG at equivalent visual quality, the best ratio of any mainstream format.
- Supports 10-bit and 12-bit color depth, HDR, and wide color gamut for professional imaging.
- Both lossy and lossless compression in a single format.
- Transparency and animation support.
- Royalty-free format backed by the Alliance for Open Media.
Compression Tips
- AVIF at quality 60-70 typically matches JPEG at quality 85+ while being roughly 50% smaller. It is the most efficient image format available today.
- AVIF encoding is CPU-intensive and slower than JPEG or WebP. Expect a few seconds per image depending on resolution and your device.
- AVIF supports 10-bit and 12-bit color depth, HDR, and wide color gamut, useful for photography and professional imaging.
- Browser support for AVIF covers Chrome, Firefox, Safari 16+, and Edge. For older Safari versions, provide a WebP or JPEG fallback.
- AVIF supports both lossy and lossless compression, plus animation and transparency.
Shrink the file, keep the quality in sight, and never hand over the original.
