Convert AVIF to TIFF Online
Runs 100% in your browser — your files never leave your device.
Print, archive, and specialist imaging software may require TIFF even when the source was delivered as AVIF. This converter uses the browser’s AVIF decoder and a JavaScript TIFF writer to create a lossless file entirely on the device, with a clear error if AVIF is unsupported.
How it works
- 1
Drop the AVIF file
Modern browser AVIF support is checked automatically.
- 2
Write the TIFF locally
Decoded RGBA pixels are encoded without leaving the tab.
- 3
Download the lossless image
Save the resulting TIFF immediately.
