These sections explain the job in plain language and set expectations for what the tool should do well.
To convert a PNG to AVIF, upload one PNG and set the AVIF quality, then export. The converter produces a single AVIF still image, aiming to keep the visual behavior of the original while shrinking the file where AVIF is supported.
When the runtime and destination support AVIF alpha, transparency is preserved in the export, so transparent PNGs can become transparent AVIF images. This makes PNG to AVIF a useful step for lightening web assets without losing their look.
All conversion happens locally in your browser, so the PNG stays on your device and nothing is sent to a server.
AVIF can shrink still-image payloads significantly compared with PNG, which helps when you want lighter assets on the web and your audience's browsers support AVIF. The quality slider lets you trade a little detail for a smaller file when that tradeoff is acceptable.
This page focuses on one still-image conversion at a time rather than processing large photo libraries in bulk. Before deploying AVIF widely, confirm that the destinations where the image will appear support the format.
