AVIF to JPG Converter

This converts between two lossy formats, so a second round of compression is applied to an image that has already lost detail. The default of 90 is set high because compatibility, not file size, is the reason to do this.

• 95–100 — Visually identical. Large files. Worth it before editing or printing.
• 85–94 — The default range, and where most people should stay.
• 70–84 — Noticeably smaller, but you are stacking two rounds of visible compression.
• Below 70 — Artefacts from both formats compound.

Expect the JPG to be considerably larger — often two to three times. AVIF is the more efficient format by a wide margin, so the same picture needs far more room as a JPG. That size increase is exactly what you are paying for universal compatibility.

Transparency needs a decision. AVIF supports an alpha channel and JPG does not, so any transparent area is painted onto the background colour you choose. White suits most uses, but match it to the destination if the image is going somewhere dark — a white rectangle around a logo cannot be removed afterwards. If you need to keep transparency, convert to PNG instead.

Animated AVIF becomes a single still image. JPG holds one still image.

Where AVIF files come from

Almost always from a website. Sites increasingly serve AVIF because it loads faster, and when you right-click and save an image you get whatever the site served — so you end up with an .avif file you did not ask for and cannot open.

You may also meet them from image optimisation pipelines, some newer phone cameras, and design tools that have added AVIF export.

When to choose a different target

• The image has transparency you need — PNG keeps it. JPG cannot.
• It is going on a website — consider keeping the AVIF, or converting to WebP, both of which are far smaller than JPG.
• You will edit it repeatedly — PNG, so repeated saves cost nothing.

Should you avoid AVIF?

Not at all, and this is worth saying on a page about converting away from it. AVIF is royalty-free, produces the smallest files of any common format, and is supported by every current browser. For images you publish yourself it is an excellent choice.

The gap is in non-browser software, and unlike HEIC's licensing problem it is closing steadily on its own. Converting to JPG is the right answer for a file you need to use elsewhere today, not a verdict on the format.
