AVIF to PNG converter

When PNG is the right target

Converting AVIF to PNG makes sense when you want to edit the image or need transparency in a format that everything understands. PNG is supported by every image editor, design tool and operating system, and because it is lossless, you can make changes and save repeatedly without the image getting worse.

Typical cases include product cut-outs and logos downloaded from a website that serves AVIF, illustrations you want to retouch, or images you need to drop into a presentation or a design tool that does not import AVIF yet.

Size expectations

AVIF achieves its small files by discarding detail in ways that are hard to see. PNG keeps every pixel, so the converted file is much larger, especially for photos. The output is passed through oxipng, which picks the most compact lossless encoding without changing any pixels, but that cannot close the gap entirely. If you just need a photo that opens everywhere and transparency does not matter, AVIF to JPG produces far smaller files.

You can reduce the size by scaling the image down: enter a maximum width or height and the image is resized with a Lanczos filter, keeping its proportions.

Limits

The converter handles still images in standard 8-bit color. Animated AVIF files are not converted as animations, and HDR images are converted to standard range without tone mapping.

Private and local

Decoding (libavif) and PNG optimization (oxipng) run as WebAssembly in a background worker in your browser. Your images are never uploaded to a server.
