Convert AVIF to JPG
100% private — runs on your device, never uploaded. Works offline once loaded.
Convert modern AVIF images into universally supported JPG files that open everywhere. Runs entirely in your browser — no uploads.
What AVIF actually is
AVIF (AV1 Image File Format) stores pictures using the same compression technology as the AV1 video codec, which is why a AVIF file can look nearly identical to a JPEG while taking up a fraction of the storage space. It supports 10-bit and 12-bit colour, HDR, and transparency — features JPEG has never had. The trade-off is that AVIF is a relatively young format, and support for opening or editing it is still patchy outside of Chrome, recent versions of Safari, and a handful of image apps.
That patchiness is the whole reason this converter exists: a photo that renders perfectly on the website you downloaded it from can show up as a blank icon or a "file not supported" error the moment you try to open it in an older photo viewer, a design tool, or a document editor.
When you actually need this
The most common trigger is downloading a product photo or blog image from a modern site that serves AVIF for bandwidth reasons, then discovering it won't attach to an email, upload to an e-commerce listing, or import into Microsoft Word or PowerPoint. Print shops and photo labs are another frequent case — most consumer and commercial printing software still expects JPEG or PNG and will simply reject an AVIF file outright.
Older Android phones, Windows 10 builds without the AV1 extension installed, and many CMS platforms and forum upload forms are also still JPEG-only. Converting once, up front, avoids a failed upload later.
What changes during conversion
JPEG uses its own lossy compression, so re-encoding an AVIF into JPEG involves a second round of lossy compression on top of the first. For photographic images the visible difference is usually small, but it isn't lossless — fine gradients and busy textures can pick up mild JPEG artefacting compared with the source. JPEG also has no alpha channel, so if the source AVIF has a transparent background, that transparency is flattened to a solid colour (typically white) in the output; use the AVIF-to-PNG converter instead if you need to keep it.
- AVIF's HDR and wide colour data is compressed down to standard JPEG colour
- Transparent areas become solid white in the JPEG output
- File size typically grows compared to the original AVIF, since AVIF is the more efficient of the two formats
Batch conversion tip
If you're clearing out a folder of AVIF exports from a phone or a screenshot tool, drop the whole batch in at once — each file converts independently and you get a single ZIP back, which is much faster than converting and re-downloading one image at a time.
Frequently asked questions
Why convert AVIF to JPG?
AVIF is very efficient but not yet supported everywhere. Converting to JPG makes the image compatible with any app or device.
Are my images uploaded?
No — everything runs in your browser and your files stay on your device.
Will the JPEG look worse than the original AVIF?
There may be a very slight quality loss because JPEG applies its own lossy compression on top of what AVIF already did, but for typical photos the difference is not noticeable to the eye.
What happens to transparent backgrounds?
JPEG does not support transparency, so any transparent pixels in the source AVIF are filled with a solid white background in the converted file.
Why is my converted JPEG bigger than the AVIF?
AVIF is generally more space-efficient than JPEG at the same visual quality, so it's normal for the JPEG version to have a larger file size.
Can I convert several AVIF files in one go?
Yes, drag in multiple files and each is converted independently, then bundled into a single ZIP for download.
Will animated AVIF images keep their animation?
No, JPEG is a static format, so only a single frame is kept if the source AVIF was animated.
Do I need any software installed to open AVIF first?
No, the browser handles decoding AVIF directly, so you don't need a codec pack or separate viewer just to run the conversion.
