AVIF to JPG — Convert in Your Browser

Why convert AVIF to JPG?

AVIF is the most efficient image format on the web and one of the least supported in desktop software. If a downloaded AVIF won't open in your editor, your CMS or your photo viewer, JPG is the format that ends the argument.

AVIF wraps the AV1 video codec around still images. It is the most efficient mainstream web image format today, often half the size of a comparable JPG at the same perceived quality.

When AVIF → JPG is the right move

Opening a saved AVIF in software that has no AV1 decoder.
Uploading to a platform whose validator only recognises JPG and PNG.
Sharing an image with someone on an older device or browser.

Quality, size and what changes

This is a lossy-to-lossy re-encode at high quality, so expect no visible change but a larger file — often twice the size, because JPG simply cannot compress as efficiently. Transparency, if present, is flattened.

What you gain with JPG: Small photographic files that open literally everywhere, from a print shop kiosk to a decade-old phone.

How it works

Drop your AVIF file above and Morphio decodes it locally, then re-encodes it as JPG using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

AVIF to JPG — frequently asked questions

How do I convert AVIF to JPG without uploading the file?

Open the AVIF to JPG page, drop your image on the drop zone and press convert. Morphio runs an in-browser image pipeline built on Canvas and WebAssembly codecs, so the AVIF data never leaves your device and no server ever receives a copy.

Does converting AVIF to JPG lose quality?

Colour profile and pixel dimensions are preserved; you choose the quality level before the file is written. Converting AVIF to JPG only rewrites the container and encoding you asked for — the source file on your disk is never modified.

Is the AVIF to JPG converter free, and how big can the file be?

Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.

Why can't I open AVIF files?

AVIF needs an AV1 decoder. Browsers ship one; many desktop viewers and older editors still do not.

Is JPG worse than AVIF?

Technically yes — AVIF is far more efficient at the same quality. JPG wins purely on compatibility.
