Frequently asked questions
What is AVIF?
AVIF is a modern image format based on the AV1 video codec. Every modern browser supports it, which makes it great for websites: pages load faster.
Is transparency preserved?
Yes. AVIF stores an alpha channel, so transparent areas of the PNG stay transparent.
Is AVIF good for screenshots and logos?
For photos and complex illustrations, yes. Screenshots with small text and logos with sharp edges may show visible artifacts with lossy compression — keep those as PNG or raise the quality.
Why does encoding take so long?
The AV1 encoder works hard to find the best way to compress every part of the image. In the browser it runs on a single thread, so a large image can take tens of seconds.
Which quality should I choose?
The default of 75 is usually indistinguishable from the original on photos. Raise it for images with text and thin lines.
Is it safe to convert my images here?
Yes. The site only downloads the converter itself; your images are processed in your browser and are never sent to a server.
