convert PNG to AVIF
PNG is lossless and therefore tends to be heavy, even for simple images. AVIF supports transparency like PNG, but with far more efficient compression, often shrinking the file by 50–80%. For the modern web, converting PNG to AVIF is one of the highest-impact optimizations. Encoding runs in the browser.
Alpha preserved, weight at a quarter of the original.
Gains add up across interfaces with many icons.
Transparency is filled with white, because the JPEG format does not support an alpha channel. If you need to preserve transparency, convert to PNG or WebP. The tool automatically warns you when this situation occurs.
Yes. AVIF supports an alpha channel, so all partial transparency (shadows, soft edges) is preserved in the conversion.
For sharp text and screenshots, lossless PNG or lossless WebP are usually safer. Lossy AVIF can soften thin edges. Review the result before publishing.
Preset conversion: PNG → AVIF. Add your files below.
Your browser cannot encode this format. Pick another one. Otherwise the file would be saved with the wrong extension.
AVIF (not supported)
Converting a 6000px image without resizing is the classic mistake: the format changes but the file stays huge.
