AVIF to JPG Converter - Convert AVIF to JPG Online Free

Convert AVIF images to JPG in your browser, one at a time or in batches. Decoding depends on your browser's built-in AVIF support, and nothing is uploaded to a server.

What AVIF to JPG Does

This tool hands each AVIF file to your browser to decode, draws the result onto an in-browser canvas, and re-encodes those pixels as a JPG using the browser's own JPEG encoder. Nothing is uploaded — the whole cycle runs on your machine. That architecture has one hard dependency worth stating up front: there is no bundled AVIF decoder here, so the conversion only works if your browser can already read AVIF. That means Chrome 85 or newer, Firefox 93 or newer, or Safari 16 or newer. On anything older the file simply fails to decode and no JPG is produced, and the fix is updating the browser rather than changing any setting on this page. Beyond that, the two formats differ in ways you will see in the output. AVIF carries a full alpha channel and JPG has none, so transparent and semi-transparent pixels are composited onto white before encoding, and converting the JPG back to PNG later will not recover them. AVIF is also usually lossy, which means the JPG encoder is compressing an image that already had detail discarded once; the two passes stack rather than cancel, and low Quality values compound artifacts around text and hard edges. Expect the JPG to come out larger than the AVIF, often substantially — AVIF's encoder is far more efficient at the same perceived quality. Converting here buys compatibility, not smaller files.

Why You'd Convert AVIF to JPG

Almost always because something downstream won't open the AVIF you already have. AVIF is still new enough that support outside modern browsers is thin.

How to Convert AVIF to JPG

Four steps, and quality is the only real decision. If the upload step reports a decode failure, check your browser version first.

1

Add one AVIF file or drop in a whole folder — every file in a batch uses the same settings

2

Set the Quality slider; 92 is the default and suits most photos, lower it only when size matters more than detail

3

Click Apply to start — the button reads "Converting..." while the browser encodes each file

4

Download the JPGs individually, or grab the whole batch as a single ZIP

Frequently Asked Questions

AVIF is an image format built on the AV1 video codec. It compresses far better than JPG at the same perceived quality, so a growing number of sites publish photos in it to speed up page loads. Your browser saves whatever the server actually sent, so the file lands on disk as .avif even though it looked like an ordinary photo in the page. Nothing went wrong with the download — it's just the format the site chose.
Most likely your browser can't decode AVIF. This tool has no bundled decoder — it relies entirely on the browser's own AVIF support, which arrived in Chrome 85, Firefox 93, and Safari 16. On anything older the decode step fails before encoding ever starts, so no output is produced. Updating to a current version of Chrome, Firefox, Edge, or Safari resolves it. No quality setting or file change will work around a missing decoder.
Chrome 85 and later, Edge on the same Chromium base, Firefox 93 and later, and Safari 16 and later, on both desktop and mobile. Anything released in roughly the last three years is fine. Older builds, some embedded in-app browsers, and a few long-term-support corporate installs still lack AVIF decoding and will fail here. If you're unsure, the fastest test is to open one AVIF file and see whether it converts.
Because AVIF compresses much more efficiently than JPEG — commonly around half the size at comparable visual quality. When you re-encode the same pixels as JPG you give up that efficiency, so growth is the normal outcome, not a fault in the conversion. Lowering Quality shrinks the JPG, but it buys those bytes with visible artifacts layered on top of what the AVIF pass already removed. Converting to JPG is a compatibility move; if you want smaller files, keep the AVIF.
Usually a little, yes. Most AVIF files are lossy, meaning detail was already discarded once when the file was created. The JPG encoder then compresses that result a second time, and the two passes stack rather than cancel out. The losses appear first as softening or ringing near sharp edges, text, and flat color boundaries. At Quality 92 the second pass is hard to spot on typical photographs. At low settings it becomes obvious, especially on screenshots and graphics.
Start with the default of 92 — close to visually lossless on photos while keeping file size reasonable. Drop toward 80 when size matters more than fine detail, such as email attachments or web thumbnails. Push to 95 or above if the JPG will be printed or edited further, since every later re-save compounds the loss. Below roughly 70, blocking and color banding show clearly on anything containing text or hard-edged graphics.
It becomes white. AVIF supports a full alpha channel, JPG supports none, so transparent and semi-transparent pixels have to be flattened onto an opaque background before the encoder will accept them, and white is what this tool fills with. Semi-transparent edges blend toward white rather than being cut off, which can leave a pale fringe around logos and cutouts. If you need the transparency kept, convert the AVIF to PNG or WebP instead.
No upload, and yes to batches. Decoding and encoding both happen inside your browser through the canvas API, so image data never leaves your device - no account, no server storage. Add as many AVIF files as you like; they run through the same Quality setting in one pass and download individually or as a ZIP. The practical limit is your machine memory and CPU rather than an upload cap.
