Convert AVIF to PNG — Free AVIF to PNG Converter
Free AVIF to PNG conversion, batches included — everything runs on your device.
Worth knowing before you start: AVIF can carry 10-bit color and HDR signalling, and this conversion cannot keep either. Everything runs through the browser's canvas, which is 8 bits per channel and sRGB, so a wide-gamut AVIF comes out as an ordinary 8-bit image. For a standard web photo that changes nothing. For an HDR still it's a real downgrade, and PNG has no way to represent what was there.

Why Convert AVIF to PNG?
AVIF is a cutting-edge format, but many applications, design tools, and workflows still do not support it. Converting AVIF to PNG gives you a universally compatible, lossless image that works in every editor, presentation tool, and print service.
PNG preserves every pixel without additional compression loss. Once converted, you can edit, crop, and re-save the image as many times as you need without any quality degradation. Transparency in the AVIF carries over to the PNG untouched.
The decode happens in the tab you already have open: LeanImg ships its codecs to the page instead of shipping your images to a server. Free, no account, nothing retained after you leave.
Keep in mind that PNG files are significantly larger than AVIF — that is what universal compatibility and lossless storage cost. If you need a smaller file that still works everywhere, AVIF to JPG is the alternative, and the PNG compressor can claw some bytes back afterward.
What changes going from AVIF to PNG
Decoding happens through the browser's own AVIF support first, and if that browser has none the converter falls back to a WebAssembly AV1 decoder, so this conversion works on an Edge or Safari release too old to display the file itself. Whatever the decoder produces is written as an 8-bit RGBA PNG and then compacted by oxipng at level 3 with no change to the pixels. Alpha comes through intact.
From here the image is lossless, which means the AV1 artifacts are now permanent residents. Smoothed textures and any banding in skies are stored exactly as decoded, and they'll survive every future save. The EXIF and XMP items an AVIF can hold are dropped, as is its ICC profile, so the PNG is untagged and reads as sRGB. An AVIF image sequence yields its first frame only.
Size moves further here than in almost any other direction on this site, because AVIF is the tightest source and PNG the loosest target for continuous tone: a photographic AVIF routinely comes back many times its size. You do this because the tool you're handing the file to can't read AVIF, which still covers a lot of design, print and office software. Don't do it to put an image on a web page, and don't expect a PNG to hold anything the canvas already squeezed out, such as 10-bit gradients or an HDR range.

What is a PNG file?
PNG became a W3C Recommendation in October 1996, designed after Unisys began enforcing the LZW patent that GIF relied on. It is lossless and only lossless: one compression method, deflate, applied after per-scanline filters. Every tool advertising a lossy PNG is really quantizing to a 256 color palette before writing an ordinary lossless PNG. Transparency comes in three grades: a real alpha channel at 8 or 16 bits, up to 256 alpha levels from a palette table, or a single keyed color.
| Released | 1996, W3C Recommendation. ISO/IEC 15948 since 2004 |
| Compression | Lossless only, deflate with per-scanline filters |
| Transparency | 8 or 16 bit alpha channel, a palette table or one keyed color |
| Animation | APNG, official only since the Third Edition in June 2025 |
| Color depth | Up to 16 bits per channel. Browser canvas APIs truncate that to 8 |
| MIME type | image/png |
How to open a PNG file
Nothing needs installing anywhere: Preview and Quick Look on macOS, Photos and Paint on Windows, and libpng as a base dependency on Linux mean GIMP, Krita and every GTK or Qt application read it. The interesting tools are the optimizers — optipng, oxipng and zopflipng rewrite the file losslessly, and LeanImg's compressor runs oxipng at optimization level 3 without ever changing a pixel.

Frequently Asked Questions
How to convert AVIF to PNG?
Drop an AVIF file — or a whole folder of them — onto the LeanImg converter and matching PNGs are written out on the spot. Everything runs client-side; there is no upload step, no queue, and no account.
Is it safe to convert AVIF to PNG online?
It is. The conversion code executes locally: your images are opened by your own browser, not by a remote service. Nothing is transmitted or retained — close the tab and every trace is gone.
How to convert AVIF to PNG on Windows?
On Windows, any of Chrome, Edge, or Firefox will run the converter. Drop the AVIF files in and save the PNGs — no codec packs, no Store extensions, no installs. Handy on machines where Photos cannot open AVIF at all.
Why are PNG files larger than AVIF?
Because PNG stores every pixel losslessly while AVIF's AV1 compression discards what the eye won't notice, the PNG re-encoding of an AVIF is usually several times bigger. You are trading bytes for a file every tool can open.
