Common use cases

People convert AVIF to JPG or PNG when their image's container format is rejected by the next tool, platform, or recipient in their workflow. AVIF ships smaller files than WebP or JPEG at the same visual quality and is now natively rendered by every evergreen browser, but the support story outside the browser is still patchy. Adobe Photoshop didn't open AVIF until version 24 (October 2022), Microsoft Office still has gaps, mainstream e-commerce uploaders (Shopify, Etsy, eBay listing tools, Amazon Seller Central, print-on-demand services like Printful and Printify) don't accept AVIF in product listings, most CMS plugins for older WordPress builds reject it, and email clients running on Outlook 2019 or earlier render the attachment as a broken-image icon. The cheapest fix is to swap the container — JPG when the recipient cares about file size, PNG when transparency or lossless reproduction matter. Doing the conversion in the browser (no upload, no signup, no watermark) keeps confidential mockups, design comps, screenshots, and product photos off third-party servers, and the tool batches up to 50 images at once so a folder of AVIFs from a stock photo site or a designer hand-off becomes one drag-and-drop step rather than 50 separate uploads to a converter that holds onto your files for "performance reasons."

Questions

AVIF Converter — Free, In Your Browser FAQ

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

Most platforms outside browsers still don't ingest AVIF. Shopify lists JPEG, PNG, GIF, WebP, HEIC, and several other formats for product media but does not list AVIF. Etsy supports `.jpg`, `.gif`, `.png`, `.svg`, and `.heic`, with no AVIF in the accepted list. Photoshop opens AVIF natively from version 24 (October 2022); earlier builds throw a "could not parse" error and refuse to import the file. Converting to JPG (smaller) or PNG (lossless) is the fastest unblock — the receiving platform usually re-compresses anyway, so it can't tell the difference between a JPG you handed it and a JPG it would have produced from your AVIF.

Does converting AVIF to JPG lose image quality?

There is one lossy step. The AVIF is decoded by the browser into a canvas, then re-encoded as JPG at quality 0.92 — the same setting iOS uses when it shares a photo to non-Apple devices. For ordinary photographs the result is visually indistinguishable from the source, but it is not bit-for-bit identical. If you need lossless preservation, pick the PNG output instead — PNG re-encoding from the canvas is lossless and preserves any alpha channel from the source AVIF.

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 the PNG output. JPG does not support an alpha channel, so any transparent regions in the source AVIF flatten to white when exported as JPG. Pick PNG to keep transparency intact — the alpha is round-tripped losslessly through the canvas re-encode. If your AVIF is a photograph with no transparency, JPG produces a much smaller file with no visible quality loss.

Will this tool stay free?

The basic workflow is designed to stay free. Paid upgrades later will focus on bigger limits, batch work, OCR, saved presets, and ad-free use.
