AVIF is a genuinely efficient modern format, often producing noticeably smaller files than JPEG at matching visual quality thanks to a more advanced underlying codec. Browser decode support has grown a great deal since AVIF first appeared, and current versions of Chrome, Firefox, Edge and Safari all handle it now, though older browser versions and some non browser software still cannot open it at all.
Because decoding depends entirely on what your browser provides, this tool checks that directly rather than assuming it will work. If AVIF decoding is not available in your current browser, the page tells you plainly instead of letting the conversion fail silently or produce a broken result.
When you need an avif to jpg converter
The most common trigger is compatibility. AVIF is newer than PNG or JPG, and plenty of software, older devices, email clients and some content management systems still cannot open it, while JPG remains readable by essentially everything that has ever displayed an image.
The second trigger is workflow. Some print services, older photo editing tools and a number of legacy asset pipelines were built before AVIF existed and simply have no path for handling it, so converting once at the point of use avoids repeated failures further down the line.
- Convert to JPG when a tool, platform or device does not accept AVIF uploads.
- Convert to JPG when the image needs to go into an older editing or print workflow.
- Check the browser support notice on this page before dropping a large batch of files.
- Keep the AVIF as your source file when possible, since it is usually the smaller format.
- Consider PNG instead of JPG if the AVIF has transparency you need to preserve fully.
Which browsers can decode AVIF today
Current versions of Chrome, Firefox, Edge and Safari all decode AVIF natively as of this writing, which covers the large majority of everyday browsing. Support arrived at different times across these browsers, so an older installed version of any of them may still lack it even if the browser name itself is on this list.
This tool checks your specific browser's actual decode capability the moment you try to convert a file, rather than assuming support based on the browser's name alone, and reports a clear message the moment a decode attempt fails so you are not left guessing why nothing happened.
What happens to transparency and quality
AVIF supports a full alpha channel, but JPEG does not, so any transparent pixels in the source AVIF need to be composited onto a solid background colour before encoding, exactly as with converting a PNG to JPG. Choose white for documents, or match your website's background colour to make the seam invisible.
The quality slider controls how much detail the JPEG encoder discards on the way out, on the familiar 0 to 100 scale. Because AVIF is itself often more efficient than JPEG at a given quality, the resulting JPG will typically be somewhat larger than the AVIF it was converted from, which is the expected trade off for universal compatibility.
How this AVIF to JPG converter works under the hood
The File API reads the bytes of the AVIF file, the browser's built in decoder turns those bytes into pixels if it can, and the canvas element's toBlob method re encodes those pixels as JPEG at your chosen quality. If the decode step fails, the tool catches that directly and explains what happened rather than showing a generic error.
None of this touches a server at any point. You can confirm the privacy claim yourself by opening your browser's network panel and watching for outgoing requests while a conversion runs, where none carrying the image file will appear.
Batch converting AVIF images that need to open avif image files elsewhere
Drop several AVIF files at once and each converts with the same quality and background settings, appearing in the results list with its own file size and download link, so a whole folder that needs to open avif image content elsewhere can be handled in a single pass. Converting a batch avif to jpeg online takes seconds rather than opening each photo individually in an editor.
Conversion runs sequentially, which keeps memory use predictable even for a large batch. A set of a few dozen typical photos finishes in a few seconds on ordinary hardware, assuming the browser can decode AVIF at all.

How to convert AVIF to JPG
- 1
Check the browser notice
Look for a warning at the top of the tool if your browser cannot decode AVIF.
- 2
Add your AVIF files
Drag one or more AVIF images onto the drop area, or click it to browse.
- 3
Set quality and background
Choose the JPG quality and the colour that should replace any transparency.
- 4
Convert and download
Press convert, watch the progress bar, then download each JPG or the whole batch.

Frequently asked questions
Common questions about the avif to jpg converter.
AVIF decode support depends entirely on your specific browser and its version. If you are on an older browser release, or one that has not added AVIF support, the browser itself has no way to read the file, which this tool detects and reports clearly rather than failing silently.
Current versions of Chrome, Firefox, Edge and Safari all decode AVIF natively as of this writing. Support was added at different times across these browsers, so keeping your browser updated is the most reliable way to ensure AVIF files open correctly.
Both formats are lossy, so converting cannot restore any detail the original AVIF encoder already discarded, and the JPEG re encoding step introduces its own small loss at the quality you choose. At 80 to 90 quality this is generally not visible at normal viewing size.
AVIF's codec is generally more efficient than JPEG's at a matched visual quality, so it is normal and expected for the resulting JPG to be somewhat larger than the source AVIF file. This is the trade off you make in exchange for universal compatibility.
No. On a browser that can decode AVIF, the entire conversion happens locally using the canvas element, and the file is never transmitted to a server. You can confirm this by watching your browser's network panel during a conversion and seeing no outgoing request.
They are filled with the background colour you choose before encoding, because JPEG has no alpha channel to store transparency in. White suits most documents. If the transparency genuinely matters, keep the file as AVIF or convert to PNG instead.
