Common use cases

People convert AVIF to JPG or PNG when the next tool, platform or recipient rejects AVIF. Current browsers can display AVIF, but support outside the browser is still patchy. Adobe Photoshop did not open AVIF until version 24 (October 2022). Some office apps and upload forms still reject it. Choose JPG for photographic content. Choose PNG when you need transparency or lossless output from the decoded pixels. JPG does not support transparency, so the tool fills transparent areas with white. The conversion runs in your browser, with no sign-up or watermark. This keeps confidential mock-ups, screenshots and product photos off third-party servers. You can convert up to 50 images in one batch. Select one output format for the batch, then download each file or a ZIP. The preview shows each converted file before download. You can remove files before conversion. Keep the AVIF source when you might need its original data later.

Questions

AVIF Converter: common questions

Why won't Shopify, Etsy, or Photoshop open my AVIF?

Many platforms outside browsers do not accept AVIF. Shopify lists JPEG, PNG, GIF, WebP, HEIC and several other formats for product media, but not AVIF. Etsy supports `.jpg`, `.gif`, `.png`, `.svg` and `.heic`. Photoshop opens AVIF from version 24 (October 2022). Earlier builds can refuse the file. Convert to JPG or PNG when the destination needs one of those formats.

Does converting AVIF to JPG lose image quality?

There is one lossy step. The browser decodes the AVIF into a canvas, then encodes a JPG at quality 0.92. The result is not bit-for-bit identical to the source. Check the output before you replace the original. Choose PNG when you need alpha transparency and no added lossy encoding.

Which browsers can run this AVIF converter?

The tool relies on the browser's native AVIF decoder, so it needs a current evergreen browser. AVIF support landed at Chrome 85 (August 2020), Firefox 93 (October 2021, enabled by default), Safari 16 (September 2022, still images), and Microsoft Edge 121 (January 2024). Older builds — including Edge 85–120, which use the older codec set — can't decode AVIF in any in-page surface, and the tool surfaces a clear error rather than silently producing broken output. If decode fails the workaround is to update to a current Chrome, Edge, Firefox, or Safari — the underlying issue is the missing decoder, not the tool.

Is there a file size or batch limit for AVIF conversion?

Each AVIF must be under 100 MB and a single batch can hold up to 50 images. Those caps protect lower-RAM devices from running out of memory during decode, since the browser materialises the full pixel grid into a canvas before re-encoding. If your batch is larger, split it into runs of 50 — each batch produces one ZIP, and you can stack the ZIPs afterwards.

Will the converter preserve transparency in my AVIF?

Only if you pick PNG output. JPG does not support an alpha channel, so transparent regions become white. Pick PNG to keep transparency. Pick JPG for photographs and other images that do not need transparency.

Will this tool stay free?

Yes. Everything this tool does is free. On some tools, a Day or Project Pass raises the file-size and batch limits if you need more.
