Convert AVIF to JPG — Free, Fast & Private
People convert AVIF to JPG because something they use cannot open AVIF. The catches are transparency, a second lossy pass and a bigger file. Everything runs in your browser — nothing is uploaded.
Why an AVIF will not open
AVIF displays in Chrome 85+, Firefox 93+, Safari 16+ and Edge 85+, but many editors, older Windows apps and upload forms reject it. AVIF explained covers why, and AVIF vs WebP vs JPEG compares the formats.
Transparency becomes white
An AVIF can have an alpha channel; a JPG cannot. MiniPx fills transparent pixels with white. To keep transparency use AVIF to WebP or AVIF to PNG.
The JPG will usually be larger
AVIF is a more efficient codec than JPEG, so the same picture at similar quality usually takes more bytes as a JPG. The measured table below shows real examples.
Picking quality for the JPG
The JPG is a fresh lossy encode. The Smart preset is the default on this page and keeps the file reasonable; Gentle uses a higher quality when you plan to edit or print. AVIF files are small, so the JPG comes out bigger; the table below shows by how much on real files.
Check the JPG against the AVIF before you save
Each row shows the AVIF size, the JPG size and the output dimensions, with a before and after slider. Batches download as a ZIP.
Animation and metadata
An AVIF image sequence is written as its first frame, with a notice. EXIF is not carried into the JPG, and orientation is applied to the pixels.

Measured 2026-10-07 in Chromium 145.0.7632.6 by running this page's converter with its default setting (JPG) on each file. The photos and scans are CC0 or public-domain files from Wikimedia Commons; the screenshot is MiniPx's own; the AVIF photo is the phone photo halved and saved as AVIF quality 60; the screenshot AVIF is MiniPx's own screenshot saved as AVIF quality 60; the transparent AVIF is the measuring script's app icon saved as AVIF quality 60. Sizes are shown as the tool shows them (1 KB = 1,024 bytes).
