How it works
- Drop your AVIF files here, or select them from a folder.
- Each AVIF is decoded and re-encoded as JPG — right in your browser.
- Adjust the quality slider if you want a smaller JPG.
- Download the JPGs individually, or as one ZIP file.
AVIF is the newest mainstream image format — many large websites and CDNs now serve it by default because it compresses photos roughly twice as tightly as JPG (JPEG) at the same visual quality. The catch: Windows Photos needs the AV1 extension installed, and any Photoshop before 2023 can't open AVIF at all, so people increasingly receive AVIF files they can't do anything with. This tool decodes AVIF and re-encodes it as JPG entirely in your browser — no upload, no install, no plugin. At the default quality the JPG looks visually identical to the AVIF; note the file will typically be larger, since you're trading AVIF's newer compression for JPG's older one.
Why use convert.pics?
- Opens files that Windows Photos, older Photoshop, and many apps still reject.
- No upload: AVIF decoding and JPG encoding both happen locally.
- Batch conversion for a whole folder of AVIF files at once.
- No account, no watermark, no daily limit.
Frequently asked questions
What is an AVIF file and where did it come from?
AVIF is an image format built on the AV1 video codec, standardized in 2019 and now used by default by many major websites and content platforms because it compresses photos significantly better than JPG or WebP at the same visual quality. You're seeing more of them simply because more of the web quietly switched to sending them.
Why won't Windows Photos (or Photoshop) open my AVIF file?
Windows needs the free AV1 Video Extension from the Microsoft Store before Photos will display AVIF, and any Photoshop version released before 2023 has no AVIF support at all, even with a plugin in some cases. Converting to JPG sidesteps both problems at once.
Does converting AVIF to JPG lose quality?
Yes, technically — JPG re-encodes the pixels rather than copying AVIF's compressed data. At the default quality setting the difference is not visible to the eye, but it's a real re-encode, not a lossless copy.
Why is the JPG bigger than the AVIF was?
AVIF's compression is noticeably more efficient than JPG's at equivalent visual quality — often by a wide margin. Converting to JPG for compatibility means giving up some of that efficiency; the JPG will typically be larger than the AVIF it came from.
How do I stop websites from giving me AVIF files?
You generally can't — the website's server decides the format it sends, not the visitor. The practical fix is converting the files you receive rather than trying to opt out of AVIF.
What happens if my AVIF file is animated?
AVIF can be animated, but JPG never can — so even a perfect converter would have to pick just one frame. This tool takes the first frame and flags it clearly in the result; if you need the animation itself, keep the original AVIF or export a GIF or video instead.
