How to Convert AVIF to JPG

Why Convert AVIF to JPG?

AVIF is an excellent format for the web, but when you need to share images via email, upload to platforms with limited format support, or print photos, JPG remains the universal standard. Converting AVIF to JPG ensures your images work everywhere — on every device, in every app, and with every service.

JPG has been the dominant photo format for decades. Email clients, social networks, messaging apps, and print services all handle JPG files without issues. The quality is excellent for photographs, and file sizes are reasonable.

Both the AVIF decode and the JPG encode run inside your browser tab. LeanImg never receives the photos, keeps no copies, and asks for no account — and it costs nothing regardless of how many files you feed it.

Note that JPG does not support transparency. If your AVIF image has transparent areas, they will be filled with white. For transparency support with wide compatibility, convert to PNG instead. A pass through the compressor afterward trims the JPG further.

What changes going from AVIF to JPG

The AVIF is decoded to 8-bit pixels, composited onto a hard-wired white where it was transparent, and re-encoded by MozJPEG at quality 85 as a progressive JPEG. There's no background color picker on this page, and no way to keep the alpha; if the picture needs both reach and transparency, PNG is the right target.

You're re-compressing a lossy image with a weaker coder, so the JPEG carries AV1's smoothing plus its own ringing around edges. At quality 85 that's hard to see on a photo at normal size. What you'll notice is the file size, which often lands somewhere near double the AVIF at that setting, since the two formats sit roughly a factor of two apart at matching quality. Lowering the slider narrows the gap at the usual cost.

Metadata is dropped wholesale: EXIF, XMP, the ICC profile and any HDR signaling, which means a wide-gamut AVIF leaves as a plain sRGB JPEG with nothing to say about where its colors came from. In exchange the file opens in Windows Photos with no extension installed, in every email client, on iOS 15 and in photo printing kiosks that have never heard of AV1. Don't convert an HDR or 10-bit original this way if you can keep the AVIF; the JPEG can't be upgraded back later.

AVIF vs JPG

What is a JPG file?

JPEG is the photographic standard the Joint Photographic Experts Group published in 1992, as ISO/IEC 10918-1 and ITU-T T.81. It cuts the image into 8x8 blocks, runs a discrete cosine transform over each one, then discards the coefficients your eye is least likely to miss — and almost every encoder throws away three quarters of the color resolution first, which is why colored text and thin diagram lines suffer. No JPEG mode has an alpha channel, so transparency has to be flattened onto a solid color.

How to open a JPG file

Every operating system opens a JPEG with no help at all: Preview, Photos and Quick Look on macOS, Photos and Paint on Windows, GIMP or Eye of GNOME on Linux, and every browser on every platform renders a .jpg inline. For scripted work, libjpeg-turbo ships cjpeg, djpeg and jpegtran, and jpegtran can rotate or crop without re-encoding on 8 pixel boundaries.
