Use native browser AVIF decoding to convert single images or batches to JPG. Choose quality and an explicit background for transparent AVIF pixels, then compare output sizes and download locally.
Simple workflow
How to use AVIF to JPG
- 1Choose AVIF files supported by your browser.
- 2Set JPG quality and the transparency background colour.
- 3Convert locally and download one JPG or the complete ZIP.

Frequently asked questions
Why might an AVIF fail?
AVIF decoding depends on the browser. A current browser may still reject corrupt files or AVIF features it does not support.
What happens to transparency?
JPG cannot store alpha transparency, so transparent pixels are composited onto the background colour you explicitly choose.
Are AVIF files sent anywhere?
No. Native decoding, canvas output and ZIP creation stay on this device.
Practical guide
Choose the JPG background explicitly
AVIF decoding uses the browser's native image engine, so support can vary by browser and AVIF feature. The conversion remains local and does not add a second decoder to shared bundles.
JPG has no alpha channel. Transparent AVIF areas are composited onto the background colour shown in the settings, so the choice is visible and repeatable.
Worked example
Export transparent artwork
- Start with
- art.avif has a transparent border.
- Choose
- Choose a white background and 90% quality.
- You get
- The JPG keeps the decoded dimensions and replaces alpha with white.
Tips for a useful result
- Use a current browser for AVIF input.
- Match the background to the final page.
- Keep the AVIF if transparency may be needed later.
