Convert AVIF to PNG
Pulling an AVIF into an editing or design pipeline calls for a format that adds zero further compression and keeps the alpha channel - PNG on both counts. This converter is free without restriction and does the whole decode-and-save locally, so the picture stays private to your device throughout.

How it works
- Add AVIF files - the checkerboard preview reveals any transparency they carry.
- Confirm the decoded result looks right at full size.
- Export as PNG, individually or batched into a ZIP.
Worth knowing
Think of this direction as extraction rather than conversion: the AVIF is a tightly packed delivery capsule, and the PNG is its contents laid out exactly, ready for work. Every pixel value the AV1 decoder produces is written to the PNG without modification, and because PNG is lossless, the file can then survive unlimited rounds of opening, editing and re-saving with nothing degrading. That stability is the entire point when an image is headed into retouching, compositing, annotation or version control.
The alpha channel is the second reason to land on PNG rather than JPG. AVIF supports full transparency, and design assets increasingly ship with it - cut-out product renders, logos, UI elements. Convert those to JPG and the transparency is flattened forever; convert here and each pixel's opacity crosses over intact, soft edges and partial translucency included. If your AVIF came from a designer or an asset library, this is nearly always the direction you want.
Two expectations are worth setting honestly. First, size: AVIF is among the densest formats ever deployed and PNG is among the most generous, so a photographic AVIF can easily grow ten-fold or more as a PNG. That is not a malfunction - it is the cost of a losslessly editable copy, and flat graphics grow far less dramatically. Second, fidelity: the PNG is a perfect record of what the AVIF decodes to, which for a web-optimised AVIF already includes that file's own compression choices. Perfect preservation of an imperfect source is still perfect preservation.
A practical pipeline note: do your edits on the PNG, then export the final result back to AVIF or WebP for delivery. Round-tripping through lossy formats between edits is the mistake this conversion exists to prevent.
AVIF alpha is stored as a separate auxiliary image item inside the file, and it may be encoded lossily even when it looks clean - converting to PNG snapshots the decoded mask into a truly lossless form, so repeated edits can never further erode partially transparent edges the way repeated AVIF re-encodes would.
What this tool will not do
- It will not shrink files - the PNG output is dramatically larger than the AVIF, especially for photographs, because lossless storage is the point.
- It cannot reconstruct detail the AVIF encoder discarded upstream; the PNG mirrors the decoded AVIF exactly, no more.
- It exports 8-bit PNG output - a 10-bit or HDR AVIF is tone-mapped down to standard range rather than preserved at full depth.
Questions people ask
Does AVIF to PNG keep transparency?
Yes, fully - AVIF alpha maps directly onto PNG alpha, with all 256 opacity levels per pixel carried across. Soft shadows and feathered edges arrive exactly as the source decodes them, verifiable against the checkerboard preview.
Is this conversion truly lossless?
The conversion adds no loss whatsoever: the PNG records the decoded AVIF pixel-for-pixel. Any compression the AVIF itself already contained is preserved as-is - nothing new is lost and nothing already lost can be invented back.
Why did my 300 KB AVIF become a 4 MB PNG?
That ratio is normal for photographic content. AVIF compresses about as hard as any format in existence, and PNG declines to discard anything, so the gap between them is the widest of any common conversion. Graphics and logos expand far less.
Which format should I convert AVIF to - PNG or JPG?
PNG when you will edit the image, need transparency, or want an archival copy that never degrades. JPG when you just need the picture viewable in older software and small enough to email. Editing suggests PNG; sharing suggests JPG.
Can I edit an AVIF file directly instead of converting?
Editor support remains inconsistent - some current tools open AVIF, many plugins and older versions do not, and repeatedly re-saving to AVIF stacks lossy generations. Converting to PNG once and editing there is the workflow that avoids both problems.
Does this work with AVIF images that have HDR or 10-bit colour?
They decode and convert, but the output is standard 8-bit PNG, so extended dynamic range is tone-mapped down. For SDR images - the vast majority on the web - the conversion is exact; for HDR masters, keep the original alongside the PNG.
