Drop one or more .tiff files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
TIFF to AVIF
Converting a .tiff image to .avif re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .tiff image to .avif re-encodes the pixels for a different balance of size, quality, and support. A .tiff file is a Tagged Image File Format raster, the long-standing archival and prepress standard for images that must not lose a single bit. Its tag-based structure lets one .tiff hold multiple pages, layers of metadata, and pixel formats from 1-bit fax scans to 32-bit floating-point channels.
An .avif file stores a still image (or sequence) coded with the AV1 video codec inside a HEIF-derived container. It is currently among the most efficient image formats deployed on the web, routinely beating JPEG by half at similar quality while adding HDR, wide gamut, and alpha. For this route the practical draw is best-in-class compression among widely supported web formats and 10/12-bit HDR and wide-gamut color, which JPEG cannot represent — balanced against encoding is much slower than JPEG or WebP, especially at high effort settings, which is worth knowing before you commit a large batch.
Why convert TIFF to AVIF?
The practical trigger for this conversion is usually a mismatch: with .tiff, files are huge — often 10x a visually identical JPEG. Switching to .avif buys you best-in-class compression among widely supported web formats, which is why it is the better fit for serving hero images and photo galleries where bandwidth savings are significant. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
TIFF vs AVIF at a glance
| Aspect | TIFF image (.tiff) | AVIF image (.avif) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | structured as Image File Directories (IFDs) of numbered tags, allowing multiple images per file | encodes AV1 intra frames; both lossy and a mathematically lossless mode are defined |
| Strongest at | archival masters for museums, libraries, and digitization projects | serving hero images and photo galleries where bandwidth savings are significant |
| Weak spot | files are huge — often 10x a visually identical JPEG | encoding is much slower than JPEG or WebP, especially at high effort settings |
| Metadata | eXIF is itself structured as TIFF tags, so TIFF holds it natively, alongside XMP packets, IPTC records, ICC profiles, and GeoTIFF georeferencing tags | eXIF and XMP are stored as metadata items in the HEIF container alongside ICC profiles or CICP color signaling, and mainstream encoders preserve them on conversion |
Pick AVIF as the output
Select .avif in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if AVIF is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid AVIF file. Outputs keep the original filename with the .avif extension.
TIFF to AVIF questions, answered
Will converting TIFF to AVIF lose quality?
Some. Since tiff is lossless-oriented and avif is lossy-oriented, the encoder will discard detail it judges least visible; the quality slider controls how aggressive that is. Keep the original .tiff if you may need a pristine master later.
Is it private to convert TIFF files here?
Yes — the .tiff file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the AVIF file work?
Chrome 85+ (2020), Firefox 93+ (2021), and Safari 16+ (2022) render AVIF natively, covering the overwhelming majority of current browsers. On the desktop, macOS 13+ and Windows (via the AV1 Video Extension) preview it, but plenty of older editing and printing software cannot open it yet.
Will the AVIF file be bigger or smaller than my TIFF?
Smaller, usually dramatically so — that is the main reason this route exists. The quality slider trades size against fidelity; the default sits at the point where most people cannot spot the difference.
What happens to the metadata in my TIFF file?
In .tiff, eXIF is itself structured as TIFF tags, so TIFF holds it natively, alongside XMP packets, IPTC records, ICC profiles, and GeoTIFF georeferencing tags. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert AVIF back to TIFF?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .tiff → .avif → .tiff is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
