Why convert TIFF to AVIF?
Converting TIFF to AVIF usually comes down to compatibility or file size. Squeezing web images as small as they will go, when you can serve a fallback to older browsers.
TIFF vs AVIF: what actually changes?
The practical differences are compression, transparency and compatibility. TIFF is lossless with supported via an alpha channel transparency; AVIF is lossy or lossless with full alpha channel transparency. The table below sets out every difference that affects the result.
| Property | TIFF | AVIF |
|---|---|---|
| Compression | Lossless | Lossy or lossless |
| Transparency | Supported via an alpha channel | Full alpha channel |
| Animation | Not supported, though it holds multiple pages | Supported |
| Colour depth | Up to 32-bit per channel, including CMYK and Lab colour | Up to 12-bit per channel, with HDR and wide colour gamut |
| Introduced | 1986 | 2019 |
| Browser support | No mainstream browser displays TIFF without conversion | Chrome from 2020, Firefox from 2021, Safari from version 16 (2022), Edge from 2023 |
| Typical size | Commonly 10–30× a JPG | Roughly 0.5× a JPG at matched quality |
| Best for | Print production, archival masters and scanned documents, where fidelity outranks file size. | Squeezing web images as small as they will go, when you can serve a fallback to older browsers. |
What is a TIFF file?
TIFF stands for Tagged Image File Format. Introduced in 1986 by Aldus, now maintained by Adobe, it uses lossless compression and is best suited to print production, archival masters and scanned documents, where fidelity outranks file size.
The print and archival standard. High fidelity, optional layers, and file sizes to match — most browsers cannot display it without conversion.
| Property | TIFF |
|---|---|
| Full name | Tagged Image File Format |
| File extensions | .tif, .tiff |
| MIME type | image/tiff |
| Introduced | 1986 |
| Developed by | Aldus, now maintained by Adobe |
| Compression | Lossless |
| Colour depth | Up to 32-bit per channel, including CMYK and Lab colour |
| Transparency | Supported via an alpha channel |
| Animation | Not supported, though it holds multiple pages |
| Browser support | No mainstream browser displays TIFF without conversion |
| Typical file size | Commonly 10–30× a JPG |
TIFF strengths
- Lossless with very high colour precision
- Holds multiple pages in one file — ideal for scans
- CMYK support makes it a print industry standard
TIFF limitations
- Browsers cannot display it at all
- Very large files
- So many optional features that support varies between programs
What is a AVIF file?
AVIF stands for AV1 Image File Format. Introduced in 2019 by Alliance for Open Media (Google, Netflix, Mozilla, Amazon and others), it uses lossy or lossless compression and is best suited to squeezing web images as small as they will go, when you can serve a fallback to older browsers.
The AV1-based successor to WebP. Best-in-class compression — often half the size of JPG — with wide, modern browser support.
| Property | AVIF |
|---|---|
| Full name | AV1 Image File Format |
| File extensions | .avif |
| MIME type | image/avif |
| Introduced | 2019 |
| Developed by | Alliance for Open Media (Google, Netflix, Mozilla, Amazon and others) |
| Compression | Lossy or lossless |
| Colour depth | Up to 12-bit per channel, with HDR and wide colour gamut |
| Transparency | Full alpha channel |
| Animation | Supported |
| Browser support | Chrome from 2020, Firefox from 2021, Safari from version 16 (2022), Edge from 2023 |
| Typical file size | Roughly 0.5× a JPG at matched quality |
AVIF strengths
- Often half the size of JPG at the same visual quality
- Royalty-free, unlike HEIC
- HDR, wide gamut, alpha and animation in one format
AVIF limitations
- Encoding is computationally expensive and can be slow
- Desktop image editors still lag on support
- Older browsers and devices need a fallback
Does converting TIFF to AVIF lose quality?
Yes, slightly — AVIF is a lossy format, so some detail is discarded during encoding. At the default 85% quality the difference is invisible to the eye for most images. Raise the slider toward 100% when archiving, or lower it when the smallest file matters most.
Two distinct things are often confused here. The first is whether the target format discards data: AVIF is lossy or lossless, so it does, in a controlled amount you set with the quality slider. The second is whether the source already lost data: TIFF is lossless, so the source holds the original detail intact.
A practical rule: converting repeatedly between lossy formats compounds the damage each time. If you expect to edit an image more than once, work in a lossless format and export to a lossy one only at the end.
Is it safe to convert TIFF files here?
Yes, and you can verify it rather than trust it. Your TIFF file is read, decoded and re-encoded inside your browser tab. There is no upload endpoint on our side, so no copy of your image exists anywhere but your own device.
Most online converters upload your file to a server, process it there and promise to delete it later. That promise is unverifiable, and it does not survive a breach, a misconfigured storage bucket or a legal request. This tool removes the question entirely: the code comes to you, the file stays put.
To confirm it for yourself, open your browser’s developer tools, switch to the Network tab, and convert a file. You will see the page assets load and nothing carrying your image leave. It also works with your connection switched off entirely, once the page has loaded.
TIFF and AVIF at a glance
TIFF files use the image/tiff MIME type and the .tif extension; AVIF files use image/avif and .avif. The summary below covers the properties that matter when choosing between them.
| TIFF | AVIF | |

| Full name | Tagged Image File Format | AV1 Image File Format |
| Extension | .tif, .tiff | .avif |
| MIME type | image/tiff | image/avif |

TIFF to AVIF: frequently asked questions
- How do I convert TIFF to AVIF?
- Open this page, drag your TIFF files onto the drop zone, and press Convert. AVIF is already selected as the output format. The conversion runs in your browser and finishes in seconds, then you download the result individually or as a ZIP.
- Is this TIFF to AVIF converter free?
- Yes, completely. There is no account, no daily limit, no watermark and no paid tier. You can convert as many TIFF files as you like, as often as you like.
- Are my TIFF files uploaded to a server?
- No. The conversion runs entirely in your browser using the Canvas API and WebAssembly codecs. Nothing about your file is transmitted to us, so there is nothing for us to store, share or lose. You can verify this by opening your browser's Network tab while converting.
- Will converting TIFF to AVIF reduce quality?
- AVIF is a lossy format, so some detail is discarded. The quality slider defaults to 85%, which is visually indistinguishable from the original for most images. Raise it toward 100% for archiving, or lower it for the smallest possible file.
- Will the file get bigger or smaller?
- AVIF files are typically roughly 0.5× a jpg at matched quality, against commonly 10–30× a jpg for TIFF. The converter shows the before and after size for every file so you can see the exact result.
- Can I convert multiple TIFF files at once?
- Yes. Drop the whole batch in and they convert one after another with individual progress. Download them one by one, or take the entire set as a single ZIP file built in your browser.
- Does AVIF support transparency?
- Yes — full alpha channel. Transparent areas in your TIFF file are preserved in the AVIF output.
- Is there a file size limit?
- Each file is capped at 50 MB, because conversion happens in your browser's memory and very large files can crash a tab, particularly on phones. There is no limit on how many files you convert.
- Does it work on iPhone, Android, Mac and Windows?
- Yes. It runs in any modern browser on any operating system — there is nothing to install. Chrome from 2020, Firefox from 2021, Safari from version 16 (2022), Edge from 2023.
- Do I need to install software or sign up?
- Neither. There is no download, no extension, no account and no email address required. Open the page and convert.
