JPG to AVIF Converter

About JPG to AVIF

JPG to AVIF takes a JPEG photo and rewrites it in the newer AVIF format, which typically reaches the same visual quality in a noticeably smaller file. It is a good fit for photo-heavy pages where JPEG weight slows loading. Since a JPEG has no transparency, the result is an opaque image.

How to use it

1. Drop a JPG or JPEG file onto the Drop a JPG file here area, or browse for it.
2. Look at the preview and the original size shown beneath the file name.
3. Choose a value on the Quality slider (it starts at 85) and press Convert to AVIF. Encoding takes a little longer than JPG output.
4. Inspect the Output, then press Download AVIF to save it, or copy it with the Copy button.

What to expect in file size

A 2.4 MB, 4032 x 3024 phone photo in JPG format

An AVIF at the same pixel dimensions, usually a good deal smaller than the JPEG. The actual figure depends on the picture, so compare the two file sizes yourself.

When to use it

• Reducing the weight of a photo gallery before publishing it on a website.
• Converting a hero photograph so the largest element on a page loads faster.
• Testing AVIF output against your existing JPEG files before a wider rollout.
• Creating a compact copy of a portrait for a newsletter template that supports modern formats.

Questions about JPG to AVIF

Does converting JPEG to AVIF lose more quality?

Yes, slightly. A JPEG already discarded some data, and AVIF discards more at lower slider values, so repeated conversions accumulate artifacts. Convert from the original camera file when possible and keep the JPEG as a backup.

What happens to EXIF data, such as GPS location?

It is not carried over. The picture is redrawn on a canvas and encoded fresh, so camera details and location tags are dropped, which is a side benefit if you plan to publish it.

Why does the first conversion take a moment longer?

The tool uses your browser's own AVIF encoder when it has one and otherwise fetches a WebAssembly encoder the first time you convert. Once loaded, it stays ready for the rest of your visit to the tab.

Will the AVIF display everywhere?

Recent versions of the major browsers can show AVIF, but older browsers, some email clients and many editing programs cannot. Keep a JPEG fallback for those audiences.
