Convert AVIF to PNG

How to convert AVIF to PNG

1. Drop your AVIF files into the box above, or click to browse. You can also paste with Ctrl+V.
2. Adjust quality or resizing under Conversion settings if you need to. The defaults suit most photos.
3. Conversion starts automatically and runs on your device — watch the progress bar for each file.
4. Download files individually, or grab everything as a ZIP.

What changes when you convert AVIF to PNG

This is the route to take out of AVIF when the image has transparency, because JPEG cannot carry an alpha channel and PNG can. It is also the route that produces the most dramatic increase in file size on this entire site.

AVIF is built on AV1, a 2018 video codec, and it is the most efficient still-image format in general use. PNG is a lossless format from 1996 that stores every pixel exactly. Converting between them means going from the most aggressive compression available to none at all, and a factor of twenty is normal — a 312 KB AVIF becoming an 11 MB PNG is not an error.

What you gain is compatibility with everything. PNG has been readable by every piece of image software since the late 1990s, whereas AVIF support outside browsers remains patchy: Windows 10 needs an extension installed, and a great deal of professional and corporate software still cannot open one.

What you do not gain is quality. AVIF is usually lossy, so detail was discarded when the file was created. PNG then stores those already-degraded pixels with perfect fidelity. Nothing is recovered — you get an exact, very large copy of a lossy image.

Two things are genuinely lost. AVIF supports 10-bit and 12-bit colour, where standard PNG output is 8-bit; on photographs the difference is invisible, but long smooth gradients can develop visible banding as 1024 steps per channel become 256. And HDR, which AVIF can carry and PNG has no mechanism for, is mapped down to standard range permanently.

If you need lossless and smaller, WebP's lossless mode sits between the two: roughly 25% below PNG on the same image, with identical alpha support, and readable by every current browser.

What is preserved

• The alpha channel exactly — both formats carry full per-pixel transparency
• Every decoded pixel, since PNG adds no compression loss of its own
• Pixel dimensions

What is lost

• HDR: AVIF can carry genuine high dynamic range, PNG cannot represent it
• 10-bit and 12-bit colour depth, reduced to 8-bit in the standard PNG path
• Animation, where the AVIF holds an image sequence
• EXIF and XMP metadata, which PNG handles poorly

What is altered

• File size grows sharply — typically eight to twenty times, because AVIF is exceptionally efficient
• Smooth gradients that relied on 10-bit precision may show banding at 8-bit

When not to convert AVIF to PNG

Do not convert if the destination reads AVIF. Every current browser does. For anything going onto a web page this is a downgrade in size by more than an order of magnitude.

Do not convert a photograph without transparency. Use JPG or WebP instead — either will be several times smaller with no visible difference, and PNG's losslessness buys you nothing on an image that was already lossy.

Do not convert an HDR AVIF and expect the highlights to survive. They are mapped to standard range and cannot be restored.

Do not use this as a way to make files smaller. AVIF is already better at that than anything PNG can do.
