TIF to AVIF
Converting a .tif 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 .tif image to .avif re-encodes the pixels for a different balance of size, quality, and support. A .tif file is an ordinary TIFF image wearing the three-letter spelling of the extension; the bytes inside are identical to a .tiff. The shorter form comes from the MS-DOS era, when the FAT file system's 8.3 naming rule allowed only three characters after the dot, and it stuck as the default on Windows software ever since.
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 TIF to AVIF?
The practical trigger for this conversion is usually a mismatch: with .tif, dual spellings trip up strict file-type filters and deduplication scripts. 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.
TIF vs AVIF at a glance
| Aspect | TIFF image (.tif) | 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 | bitstream-identical to .tiff: an IFD-and-tag structure defined by the TIFF 6.0 specification | encodes AV1 intra frames; both lossy and a mathematically lossless mode are defined |
| Strongest at | document-imaging and fax archives, which overwhelmingly use the three-letter form | serving hero images and photo galleries where bandwidth savings are significant |
| Weak spot | dual spellings trip up strict file-type filters and deduplication scripts | encoding is much slower than JPEG or WebP, especially at high effort settings |
| Metadata | identical to .tiff — native EXIF tags, XMP, IPTC, and ICC profiles all persist regardless of which extension spelling the file uses | 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.
TIF to AVIF questions, answered
Will converting TIF to AVIF lose quality?
Some. Since tif 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 .tif if you may need a pristine master later.
Is it private to convert TIF files here?
Yes — the .tif 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 TIF?
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 TIF file?
In .tif, identical to .tiff — native EXIF tags, XMP, IPTC, and ICC profiles all persist regardless of which extension spelling the file uses. 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.
