Lightning Fast

Convert multiple images at once — encoding runs in a background worker so the page never freezes.

Any-to-Any Conversion

Turn JPEG, PNG, GIF, AVIF, WebP, BMP or TIFF into JPG, PNG, WebP, AVIF or GIF — pick any output format.

Smaller File Sizes

WebP and AVIF typically deliver 25–50% smaller files than JPEG at the same visual quality.

Why convert PNG to AVIF?

Large PNGs are one of the most common causes of slow pages, and AVIF is the strongest fix: screenshots and graphics regularly compress 80–90% smaller while transparency survives intact. Drop PNG files below and the WebAssembly AVIF encoder converts them in a background worker — the files never leave your machine.

Frequently Asked Questions

Does AVIF support PNG transparency?
Yes. AVIF has full alpha-channel support, so transparent and semi-transparent pixels in your PNG are preserved in the converted file.
How much smaller will an AVIF be than my PNG?
It depends on the content, but 80–90% savings are common for screenshots and UI graphics at the default quality. Even complex images usually shrink by well over half.
Is AVIF good for logos and sharp-edged graphics?
Yes, at high quality settings. If you notice softness around crisp edges, raise the quality slider — the file will still be far smaller than the PNG original.
