JPEG has no alpha channel, so transparent pixels are composited onto the fill colour below and cannot be separated out again.
AVIF to JPEG converter
Get an AVIF into the one format nothing rejects — compact, and with a fill colour of your choosing behind any transparency.
- Free, no signup
- Runs in your browser
- Nothing uploaded
- JPEG cannot store transparency — transparent areas are filled with the colour you choose below.
- AVIF decoding requires a reasonably current browser; an older one will report a decode error instead of producing a wrong file.

Why this conversion
When AVIF to JPEG is the right move
When an AVIF needs to go somewhere old — a print workflow, a legacy CMS, an email attachment, a form written a decade ago — JPEG is the format with the fewest ways to fail. It is not efficient by modern standards, but it is understood absolutely everywhere, which is the only property that matters when something on the other end is refusing your file.

Two things change on the way. The alpha channel disappears, since JPEG has never supported transparency, so anything see-through is painted onto a solid colour first. And because AVIF is generally lossy already, this is a second lossy pass over the same picture — keep the quality high and it stays close to invisible.
Reach for it when
- The destination accepts JPEG and little else.
- The image is photographic, which is what AVIF is usually used for anyway.
- You need a small file and do not need transparency.
The trade-off
What you gain and lose going AVIF to JPEG
JPEG sits between the two. Expect the file to grow relative to the AVIF — AVIF's whole purpose is beating older codecs — but nothing like the growth a lossless PNG would bring.
AVIF is normally lossy, so JPEG encoding compresses an already-compressed picture. Quality above 85 percent keeps the two sets of artefacts from compounding visibly.
How it works
Converting AVIF to JPEG, step by step
1Choose your AVIF file
Browse or drop it onto the panel. Up to 25 MB. The file is decoded by your browser and is never uploaded anywhere.
2JPEG is already selected
The target is preset to JPEG for this conversion. Only formats your browser can genuinely encode are offered, so nothing hands you a renamed PNG.
3Set quality and background
JPEG is lossy and cannot store transparency, so the dial trades size against detail and the colour picker decides what fills any transparent areas.
4Compare, then download
Original size, converted size and the percentage difference are all shown before you commit — including the cases where converting makes the file bigger.
AVIF to JPEG questions
Pick a question to see the answer.
Compatibility, almost always. AVIF is the better format on every technical axis, but it is barely a few years old and a great deal of software has not caught up. JPEG is the lowest common denominator that everything accepts.
Usually somewhere between 30 percent and double, depending on content and the quality setting. AVIF is roughly twice as efficient as JPEG at matched visual quality, and that gap is what you are giving back.
The transparent areas are composited onto your chosen fill colour before encoding. White is the default; converters that skip this step produce black, which is why logos so often arrive on a black rectangle.
