More about converting PNG to AVIF
AVIF is a modern image format built on the AV1 codec that reaches noticeably smaller file sizes than PNG and even WebP, while still supporting transparency and high quality. Converting PNG to AVIF is a simple way to cut page weight and speed up loading.
The conversion happens entirely in your browser using the Canvas API and the browser's built-in AVIF encoder. Nothing is uploaded, there is no signup and no watermark. You can convert up to 20 PNGs at once and download them as a ZIP.
Keep in mind that AVIF is best for websites and modern apps. If a file has to open on older software or an exam portal that only accepts JPG or PNG, convert to those formats instead using our Image Converter.
