Convert AVIF to PNG

PNG is the safe universal destination for an AVIF you need to open elsewhere: it keeps the alpha channel and is readable by everything. The trade-off is size — a lossless PNG of a photograph is dramatically larger than the AVIF it came from.

Best for: Getting AVIF images with transparency into editors and tools that reject AVIF.

What to know

  • Transparency is preserved in full.
  • Expect a very large increase in file size — often ten times or more for photographic content.
  • OxiPNG optimisation runs automatically to minimise the result.

About AVIF

Built on the AV1 video codec and standardised in 2019 — currently the strongest compression available in a widely supported still image format.

  • Encoding is genuinely slow: seconds per image rather than milliseconds.
  • Not supported by Safari before version 16, nor by much desktop software.
  • At aggressive settings it smooths fine texture rather than adding blocky artefacts, which some find worse.
Support:
Chrome, Edge, Firefox, Opera and Safari 16+. Roughly 93% of users.
Transparency:
Full alpha, efficiently compressed.

About PNG

A lossless format built for graphics, screenshots and anything needing a real alpha channel.

  • Pixel-exact: what goes in comes out, byte for byte.
  • Full 8-bit alpha channel with no fringing.
  • The right answer for screenshots, logos, line art and UI assets.
Support:
Every browser ever shipped.
Transparency:
Full 8-bit alpha.

Frequently asked questions

Why is the PNG so much larger than the AVIF?
AVIF is a highly efficient lossy codec; PNG is lossless with 1990s compression. For a photograph the difference is routinely tenfold or more. This is expected, not a fault of the conversion.
