Drop AVIF files here — or any picture

One file or a whole folder. Each one is converted on its own terms.

Paste works too, or drop a whole folder.

Drop AVIF files saved from the web or exported from a phone. Each is written as JPEG at matched quality. Transparent AVIFs wait for a background colour, because JPEG cannot hold transparency.

Why AVIF needs converting

AVIF is the newest format a browser commonly serves, and much software has not caught up: older Windows photo viewers, office suites, many upload portals and some messaging apps refuse it. JPEG opens everywhere. The AVIF is decoded by this browser's own decoder — current Chrome, Edge, Firefox and Safari all have one; the empty converter shows whether this one does.

What changes

AVIF can store 10 or 12 bits per channel and wide-gamut colour. A browser decodes to 8 bits per channel in sRGB, so the JPEG is 8-bit sRGB; extra depth and any HDR rendition do not survive. JPEG is lossy, so the quality is searched until the JPEG measures visually identical to the decoded AVIF (0.990 at 512 px). Expect the JPEG to be larger than the AVIF — that is the cost of a format everything opens.

Questions about AVIF to JPG

Why can't I open AVIF files?
AVIF is recent, and much desktop software, many portals and some apps have not added support. Converting to JPG gives a file every app opens.
Does AVIF to JPG lose quality?
JPEG is lossy, but the quality is searched until the JPEG measures visually identical to the decoded AVIF by multi-scale structural similarity, and the score is shown.
What happens to 10-bit or HDR AVIF?
The browser decodes it to 8 bits per channel in sRGB before anything is written, so the JPEG is a standard 8-bit picture. The extra depth is not carried over.
What happens to a transparent AVIF?
You choose white, light grey or black for the transparent areas before the JPG is written.
Are my files uploaded?
Nothing is uploaded: the picture is read, converted and checked in this browser tab.
