TIFF to AVIF pairs an archival source with the most space-efficient modern delivery format. It is ideal for putting museum scans, product shots, or artwork online: the AVIF looks nearly identical to the master at a small fraction of the size.
What changes when you convert TIFF to AVIF
AVIF uses lossy compression, which shrinks the file by discarding fine detail your eye is unlikely to notice. That is ideal for sharing and web use; keep the original TIFF if you need a pristine master for editing or print.
About the TIFF format
TIFF stores images with lossless (or uncompressed) data and supports layers, high bit depths, and CMYK, which is why it is a staple in publishing, scanning, and archiving. The trade-off is very large file sizes. In everyday use, TIFF is chosen for document and photo scanning, professional print and publishing masters and long-term archival of high-quality images. It opens in Windows Photos, macOS Preview, and professional imaging software.
About the AVIF format
AVIF often beats WebP and JPG on file size at the same visual quality, and it supports HDR, wide colour, and transparency. Browser support is now broad, though some older desktop apps still cannot open it. In everyday use, AVIF is chosen for high-efficiency web images, HDR and wide-gamut photography online and replacing large JPGs to cut bandwidth. It opens in modern browsers and recent operating systems.
TIFF vs AVIF
TIFF is best known for lossless, high bit-depth quality, while AVIF stands out for best-in-class compression efficiency. Choosing between them comes down to where the file needs to go next.
Common use cases
People convert TIFF to AVIF for jobs such as high-efficiency web images, HDR and wide-gamut photography online and replacing large JPGs to cut bandwidth. It is especially common when a TIFF file arrives from one system but needs to work in another that standardises on AVIF.
When to convert TIFF to AVIF
Reach for TIFF to AVIF when your destination expects AVIF — for example high-efficiency web images, HDR and wide-gamut photography online and replacing large JPGs to cut bandwidth. It is the right move when you receive a TIFF file but the app, website, or person you are working with cannot use it. Bear in mind that limited support in older software and print tools, so keep your original TIFF if you might need it again.
How to convert TIFF to AVIF
- Upload your TIFF file to the converter at the top of this page - AVIF is already selected as the output.
- Check the size limit shown on this page, then drag and drop or browse for your file.
- Confirm AVIF is still the target format, or pick a different one from the grid.
- Start the conversion and download your AVIF file the moment it is ready.
Quality tips
Always start from the largest, highest-quality TIFF you have. If AVIF still needs to fit a size or pixel budget, run the result through our Compress or Resize tools rather than re-saving repeatedly, which degrades quality.
Platform compatibility
The TIFF to AVIF converter runs on Windows, macOS, Linux, Android, and iOS - anywhere with a modern browser, with no plugins or permissions required. Once exported, AVIF opens in modern browsers and recent operating systems.

Troubleshooting
- AVIF is lossy, so each re-save loses a little more detail. Convert from your original TIFF rather than from an earlier AVIF export.
- If the file exceeds the limit shown below, compress images, trim video, or split archives before retrying.
- If conversion fails, confirm the extension matches the real format — renaming a file alone does not change its contents.
- SVG and HEIC inputs sometimes need a moment longer on the first conversion.
- Transparency does not survive every target format — use PNG or WebP if an alpha channel matters.
