Last updated
Quick answer: To convert AVIF to TIFF, add the AVIF file to the iHateFiles AVIF to TIFF converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. TIFF is lossless, so nothing degrades further, though the damage AVIF already did cannot be undone.
Should you convert AVIF to TIFF?
Do this when you are about to edit the file and want no further loss. Do not do it hoping to improve a AVIF: TIFF preserves what it is given, including the damage.
AVIF is lossy and TIFF is not
Moving from AVIF to TIFF stops any further loss, but it cannot undo what AVIF already discarded: that detail was thrown away when the file was first written and is not in it any more. Expect the TIFF to be considerably larger while looking exactly the same, because it is now storing the AVIF artefacts faithfully too.
Expect a much larger file
TIFF stores every pixel exactly, including the compression artefacts the AVIF already has. The file will grow, sometimes by a factor of ten, without looking any better. Do this when you need to edit without further loss, not to improve the image.

What usually goes wrong
About the AVIF. Reading AVIF is nearly universal; writing it is not. A browser without an encoder quietly hands back a PNG instead of refusing, so the conversion looks as though it worked. Current Chrome on macOS is one of them. This site checks for a real encoder first and says so when there is none.
About the TIFF. Because TIFF can contain many different compressions, a file that one program writes is occasionally one another program cannot read. Converting it to PNG settles the argument.
How to convert AVIF to TIFF
- Add your AVIF file. It is read from your disk and stays there.
- Check the settings. The output format is already set to TIFF.
- Press convert and the TIFF file is saved back to your device.
Questions
How do I convert AVIF to TIFF?
Open this page, add your AVIF file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this AVIF to TIFF converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to TIFF lose quality?
TIFF is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several AVIF files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
