Why you end up with AVIF files
Some image services and websites serve pictures as AVIF because the files are small. When you save one of those images, you get an .avif file, and that is where the trouble starts: older photo viewers, office programs, some image editors and many upload forms do not know the format. Converting to JPG solves it in one step, and PNG is there when you need transparency.
Browser support
This converter uses the AVIF decoder that is built into your browser, so no extra download is needed. Chrome, Edge, Firefox and Safari all support AVIF in their current versions. On an older browser the image shows an error in the list instead of a result; update the browser and try again.
After converting
AVIF images from websites are often large in pixels. The image resizer brings them to the size you need, and the image compressor squeezes the JPG further for email. For WebP files, the WebP converter does the same job.

- 2Drop one .avif file or a whole batch on the box. They convert immediately.
- 3Download each file, or all of them in one ZIP.
Frequently asked questions
What is an AVIF file?
AVIF is an image format based on the AV1 video codec, from the Alliance for Open Media. According to Google's Chrome team, it gives significantly smaller files than JPG or WebP, so some websites and image services deliver their pictures as AVIF. Plenty of desktop programs and apps cannot open it yet.
Which browsers can convert AVIF?
Current versions of Chrome, Edge, Firefox and Safari can all open AVIF; for Safari that means iOS 16 or macOS Ventura and later. If your browser cannot read the file, the list shows a clear message, and updating the browser usually fixes it.
Should I choose JPG or PNG?
JPG, also called JPEG, for photos you want to share, upload or print, since the files stay small. PNG when the AVIF has a transparent background or you want to edit the image without adding compression.
Why do the colors look slightly different?
Some AVIF images use HDR or a wide color range. JPG and PNG from a browser are saved in standard sRGB colors, so very bright or saturated areas can look a little calmer after converting.
Are my images uploaded?
No. Your browser decodes the AVIF and writes the new file on your device. Nothing is sent to a server.
