How to convert AVIF to PNG
Add one or more AVIF files, pick a quality level if the option is shown, and press Convert. Each image is decoded, redrawn on a canvas and saved again in the PNG format. Converting several files at once is supported, and the results can be downloaded together as a ZIP archive.
AVIF and PNG compared
AVIF is based on the AV1 video codec. It commonly reaches the smallest file size of the mainstream web formats and keeps transparency and wide colour. It works best for modern websites that want the smallest possible images, and is a weaker choice for older browsers and desktop software that cannot open the format yet.
PNG stores images without losing a single pixel and supports a full alpha channel, so transparent areas stay transparent. It is the better fit for logos, icons, screenshots, line art and images that need transparency, while it is less suitable for large photographs, where the file size grows quickly.
Nothing is thrown away
PNG stores the image without discarding detail, so the result is pixel-for-pixel what came out of the decoder. Be aware that a lossless format cannot restore detail that was already lost in the source file.
What to check after converting
- Open the result at full size and look at edges, text and flat colour areas first — that is where compression artefacts appear.
- Compare the file size against the original. If a PNG file is larger than the AVIF source, lower the quality slider or reconsider the format.
- Check that the image dimensions are unchanged. Conversion never resizes an image; use the resizer tools for that.
Format support in browsers
Saving files relies on the image encoders built into your browser. PNG, JPG and WebP are available almost everywhere. AVIF encoding is only present in some recent browsers, and the tool will tell you clearly when the format you picked cannot be written on the device you are using, rather than producing a broken file.
