Convert AVIF to JPG for Universal Compatibility

Where AVIF comes from and why you have one

AVIF was published by the Alliance for Open Media in 2019 and rolled out across browsers between 2020 and 2023. Because it is royalty-free and compresses extremely well, large publishers and CDNs adopted it quickly. If you saved an image from a news site, a stock library or a modern e-commerce store and got a .avif, that is why.

Outside the browser the picture is different. Windows needs an extension from the Microsoft Store, many versions of Photoshop need a plugin, and a great many web forms, print services and marketplace uploaders reject the extension without explanation.

What the conversion costs

For an ordinary photograph destined for email, a document or a listing, none of those losses are visible. For HDR photography you are genuinely losing range, and it is worth keeping the AVIF as the master.

AVIF, WEBP or JPG for your own site

• AVIF — best compression, best for large hero photographs, slower to encode.
• WEBP — nearly as small, encodes fast, supported slightly more widely in tooling.
• JPG — the fallback everything understands. Always keep one.

Privacy

Nothing is uploaded. The file is decoded and re-encoded by your own browser using the Canvas API, so the image never leaves your device and there is no queue, no size cap and no account.
