Convert AVIF to JPG, PNG, WEBP, ICO, PDF or TIFF
One AVIF file, six possible outputs. Decoding happens natively in your browser, and re-encoding uses WebAssembly where needed — nothing is ever uploaded anywhere.

What each output format is actually good for
JPG
Universal compatibility. Lossy compression at 92% quality by default here — the safest choice when the destination app or website doesn't recognize AVIF at all.
PNG
Lossless, with transparency support carried over from the source AVIF. Larger files than JPG, but no re-compression artifacts — good for graphics or further editing.
WEBP
Broadly supported since 2020 across Chrome, Firefox, Safari 14+, and Edge — a solid middle ground when AVIF itself is too new for where the image is going.
ICO
Windows/macOS icon and favicon container. This tool writes a single PNG-compressed icon resized to a maximum of 256×256px.
Wraps the image as a single, full-page PDF sized exactly to the photo's pixel dimensions — handy for sending a photo as a "document."
TIFF
An archival raster format still used in print workflows. The browser-side encoder used here produces uncompressed TIFF files, so expect a larger file size.
Why AVIF still needs a converter like this
AVIF is built on AV1, a royalty-free video codec, which is exactly why its browser support spread faster than HEIC's ever did — no licensing fight to hold it back. Chrome, Firefox, and Edge added AVIF support in 2020-2021; Safari followed in version 16 (2022). The gap is everything older than that, plus a lot of desktop software, mail clients, and CMSes that still don't expect to see a .avif file.
| Capability | Support |
|---|---|
| Decoding your AVIF file (this tool) | Any current browser — done with the browser's own native image decoder, no library needed |
| Viewing a raw .avif file directly (no converter) | Chrome, Firefox, Edge, Safari 16+ · Safari <16, many older apps |
| Encoding to JPG / PNG / WEBP (this tool) | All modern browsers |
| Reading the AVIF file itself in this tool | Depends on your browser — if it can't decode AVIF at all, you'll get a clear error rather than a broken result |
Good to know before you convert
AVIF can store 10- or 12-bit color and HDR metadata. Every output format offered here is 8-bit SDR, so that extra tonal range is flattened during conversion.
Like WEBP, AVIF can hold multiple frames. This tool converts the first frame only — every output format here is a single still image.
PNG, WEBP, and ICO keep an alpha channel from the source AVIF. JPG, PDF, and TIFF here flatten transparency onto a solid background instead.
That's a real limitation of the browser-side TIFF encoder we use, not a hidden setting — expect a notably larger file than the source.
Your photos never leave your device
Decoding the AVIF file and re-encoding it into JPG, PNG, WEBP, ICO, PDF, or TIFF all happen locally in your browser. There's no upload step, no server processing, and nothing is retained after you close the tab.
Frequently asked questions
Why won't my AVIF image open in Safari, older browsers, or Windows Photos?
AVIF runs on the royalty-free AV1 codec, so support spread quickly: Chrome, Firefox, and Edge since 2020-2021, Safari since version 16 (2022). Anything older, or Windows Photos without the AV1 extension, can't open it directly. This tool decodes AVIF with the browser's own native support, so it works on any current browser.
Which formats can I convert my AVIF file to?
JPG, PNG, WEBP, ICO, PDF, and TIFF — pick any of them from the dropdown next to each uploaded file.
Why is my exported TIFF file so large?
The browser-side TIFF encoder this tool uses currently writes uncompressed files. It's a real limitation of that library, not something you're doing wrong.
Why did my AVIF file fail to load or convert?
Almost always it's a browser that can't decode AVIF yet — Safari before version 16, or an older Chromium or Firefox build. This tool tells you clearly instead of producing a broken file; updating your browser or switching to a recent Chrome, Firefox, or Edge fixes it.
Do you store or see my photos?
No. Decoding happens with the browser's own native image support, and re-encoding happens locally too, using WebAssembly for TIFF and PDF. Nothing is uploaded to a server, and nothing is retained once you close or refresh the page.
