Modern Formats
AVIF Converter
Convert AVIF to JPG, PNG or WebP — or encode JPG/PNG/WebP into AVIF. Everything runs locally in your browser: free, private, unlimited.
Your files never leave your device — conversion runs locally in your browser.
To convert AVIF, drop files above — AVIF decodes to JPG, PNG or WebP, and JPG/PNG/WebP encode into AVIF, all in your browser with no upload. Encoding to AVIF is the slow direction (that is where the small files come from); a progress bar keeps you posted. Decoding back out is quick.
Honest limits
- Encoding to AVIF is slow by design — a progress bar tracks it; decoding is quick.
- HDR and 10-bit sources come out as standard 8-bit SDR.
- EXIF survives only into JPG output.
Need more than a browser can do? Desktop browsers go further than phones — and Media Moana converts at scale on hosted infrastructure.
How it works
Drop your files
Drag AVIF files into the drop zone, click to browse, or paste from the clipboard. Whole folders work too.
Convert locally
Each file is decoded and re-encoded to JPG right in your browser — no upload, no queue. Adjust quality or size first if you like.
Download
Save converted files one by one, or download the whole batch as a ZIP. Originals stay untouched on your device.
About the formats
AVIF — AV1 Image File Format
AVIF is a modern royalty-free image format based on the AV1 video codec, championed by Netflix, Google and Mozilla. It delivers noticeably smaller files than JPEG and WebP at the same visual quality and supports HDR and transparency. Browsers now display AVIF natively, but most desktop software, CMSs and upload forms still don't accept it — so files saved from the web often need converting back to JPG or PNG.
JPG — JPEG
JPEG (.jpg) is the most universally supported image format in existence. Every browser, OS, app, printer, government form and photo lab accepts it. It uses lossy compression tuned for photographs, supports EXIF metadata, and at quality 85–95 is visually indistinguishable from the source for most photos — the safe default whenever compatibility matters.
Frequently asked questions
Is this safe? Do my photos get uploaded?
No upload happens — ever. Converting AVIF to JPG runs entirely inside your browser using WebAssembly. Your files never leave your device, nothing is stored on any server, and the tool even keeps working if you go offline after the page loads. That's also why there are no file size limits, no queues and no sign-up.
Which output format should I pick for AVIF files?
JPG is the safe default — small files that open absolutely everywhere; PNG is lossless and keeps transparency, the right base for further editing; WebP gives the smallest files for the web; AVIF shrinks images even further where it's accepted. You can switch the output format and re-convert the same batch without re-adding files — nothing re-uploads, because nothing was uploaded in the first place.
Can I convert multiple AVIF files at once?
Yes — drop in as many files as you like. Because conversion happens on your own computer instead of a server, there is no per-file fee, no daily cap and no waiting in line. Files are processed one after another, and you can download each JPG file as it finishes or grab the whole batch as a single ZIP.
Why does encoding to AVIF take longer than decoding?
AV1 encoding is computationally heavy by design — that's where AVIF's small file sizes come from. Decoding (opening AVIF files) is quick, but encoding a large photo to AVIF can take several seconds. A progress indicator keeps you posted, and your machine does the work, so there's still no upload and no queue.
Is there a file size or quantity limit?
There is no hard limit. Server-based converters cap uploads because your files consume their bandwidth and CPU; here converting AVIF to JPG happens on your machine, so the only practical limit is your device's memory. Desktop browsers comfortably handle very large files and big batches.
