AVIF to JPG
Convert AVIF images to JPG in your browser. Free and private, no upload. Opens AVIF files that editors and uploaders reject.
About this tool
AVIF is the newest and most efficient web image format, which is exactly why almost nothing outside a browser can open it yet. If you saved an AVIF from a website and need it as a normal photo file, this tool converts it to JPG locally in your browser.
Expect the JPG to be larger than the AVIF; AVIF's compression is simply that good. The image itself is decoded at full quality and re-encoded as a high-quality JPG.
Common uses
- Open images saved from modern websites in Photoshop, Windows Photos, or older tools
- Upload a web-saved AVIF to a form that only accepts JPG or PNG
- Convert AVIF product images from a CDN back into an editable format
Automate via API
The same conversion is available as a REST endpoint for scripts, pipelines, and backends. POST the file, get the converted file back:
curl -X POST https://formatably.com/api/v1/tools/avif-to-jpg \ -H "X-Api-Key: YOUR_API_KEY" \ --data-binary @photo.avif \ -o photo.jpg
Direct requests accept up to 4 MB; the large-file flow handles up to 100 MB. Both are covered in the API documentation · Get an API key
AVIF notes
AVIF is the image format derived from the AV1 video codec, offering the best compression of any mainstream format. Browsers and CDNs increasingly serve it, but most editors, upload forms, and older software cannot open it.
- Right-click-saving an image from a modern website often yields AVIF even when the page showed it as a JPG.
- Converting AVIF to JPG or PNG grows the file; that is expected, AVIF is simply that efficient.
- Very old browsers cannot decode AVIF; this tool needs a 2023-or-newer browser.
JPG notes
JPG (JPEG) is the universal photo format: every camera, phone, website, printer, and government upload form accepts it. It compresses photos well but does not support transparency, and each re-save loses a little quality.
- JPG has no transparency; transparent areas are filled with white during conversion.
- JPG is lossy: converting into it trades a small amount of quality for compatibility and size.
Frequently asked questions
Why did I end up with an AVIF file?
Modern sites and CDNs (including many image CDNs and WordPress hosts) automatically serve AVIF to browsers that support it. When you save the image, you get the AVIF bytes even if the page called it a .jpg.
What happens if the AVIF has transparency?
JPG cannot store transparency, so transparent regions are filled with white. If the image is a logo or graphic with a transparent background, use AVIF to PNG instead to keep it.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly and the canvas API; your files never leave your device. There are no ads and no trackers on tool pages. You can verify this yourself: open your browser's developer tools, watch the Network tab while converting, and you will see no upload requests. It even works offline once the page has loaded.
Is there a file size limit?
In the browser there is no hard limit; you are bounded only by your device's memory, and files of a few hundred megabytes are usually fine. The REST API accepts files up to 4 MB in a direct request, or up to 100 MB using the large-file upload flow described in the API docs.
