Convert AVIF to TIFF Online — Free
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.
About this tool
AVIF to TIFF, into the print format
AVIF is the modern web compression format; TIFF is the lossless heavyweight of print, scanning, and archival work. The conversion moves your image into the format print shops and professional workflows accept, with every pixel preserved exactly.
The size trade is the point
TIFF files are enormous compared to AVIF — that is not a side effect, it is the format: no lossy compression, no palette, just your pixels stored completely. Expect the file to grow substantially and carry every bit of detail the AVIF contained.
When TIFF is the right target
Sending an image to a print service, archiving at maximum fidelity, or feeding professional editing software that prefers TIFF — these are the destinations. For web use, AVIF to PNG or WebP keeps files manageable.
Frequently asked questions
Why is my TIFF so much larger than the AVIF?
TIFF stores losslessly while AVIF compresses aggressively — the size growth is the discarded compression, with every pixel restored to full detail.
Does TIFF support transparency?
TIFF carries an alpha channel, so transparent areas in the AVIF transfer — though print workflows typically expect opaque images anyway.
Is the conversion lossless?
Yes — TIFF stores every pixel exactly, so the conversion preserves the image completely and only the file size changes.
