Why convert AVIF to JPG?

AVIF is one of the newest image formats — released in 2019 and based on the AV1 video codec. It produces files roughly 30–50% smaller than JPG at the same visual quality. The catch is compatibility: many image editors, older browsers, social media platforms, email clients, and printing services still don't accept AVIF files.

JPG is the opposite — it's been around since 1992 and works literally everywhere. Every photo viewer, every website upload form, every printer, every messaging app supports JPG natively.

If you've downloaded an AVIF and a friend or service can't open it, converting to JPG instantly solves the problem. You'll trade some file size for universal compatibility.

About AVIF

AVIF (AV1 Image File Format) was developed by the Alliance for Open Media and released in 2019. It uses the same compression engine as the AV1 video codec, supports HDR and wide color gamuts, and is the most efficient widely-supported image format available today. Browser support is solid in Chrome, Firefox, and Safari 16+, but legacy software still struggles with it.

About JPG

JPG (Joint Photographic Experts Group) was standardized in 1992 and has been the default photo format for three decades. It uses lossy compression that's optimized for photographic content and is supported universally — every operating system, browser, image editor, and online service handles it natively.

Quality and file size

Going from AVIF to JPG means re-encoding with an older, less efficient compression algorithm. Expect the output JPG to be 2–4 times larger than the source AVIF at comparable quality. There's a small additional quality loss from the second encoding pass, but it's almost never visible on photographic content.

Expect the file to grow. Re-encoding a 325 KB AVIF produced a 1,321 KB JPG — 4.1× larger at comparable visual quality.

That gap is the whole point of AVIF — you’re giving up its efficiency to gain compatibility with software that can’t read it. There’s a second round of lossy compression here too, invisible on photographs but worth avoiding on anything you’ll re-edit. Note that the PNG and JPG above are re-encoded from this AVIF rather than from the original photo, so both land smaller than the same shot converted from a camera JPG — AVIF has already discarded the detail they would otherwise have to store.

JPG has no channel for transparency, so anything transparent is filled — usually white — the moment you convert. There is no undoing it afterwards: keep the original if you need the cut-out.

The same crop encoded to the same file size: JPG at quality 82 (90 KB) and AVIF at quality 92 (83 KB) — This is what you give up going the other way. At equal file size JPG bands the smooth sky where AVIF holds it — so if you convert to JPG, use a generous quality setting and accept the larger file rather than matching the AVIF’s size.

Frequently asked

Why is the JPG file bigger than the AVIF?

AVIF uses a more modern, efficient compression method (AV1) that produces smaller files than JPG at the same visual quality. When you convert AVIF to JPG, you're moving to a format that needs more bytes to represent the same image.

Will the photo look worse?

Not in any way you can see. There's a tiny re-encoding loss but JPG at standard quality settings preserves photographic detail extremely well.

Why doesn't my photo editor open AVIF directly?

AVIF is recent enough that older versions of Photoshop, GIMP, and many other editors don't support it yet. Converting to JPG is the fastest workaround until your software updates.
