FAQ

What is AVIF?

AVIF is a modern image format based on the AV1 codec. It often delivers similar visual quality to JPEG or PNG at a much smaller file size.

Do you upload my images?

No. Conversion happens in your browser. Images stay on your device and are not sent to SinceNew servers.

Which formats can I convert?

JPEG, PNG, WebP, GIF, and BMP. Up to 10 images per batch. Animated GIFs are converted as a single frame.

Why is conversion slow on my phone?

AVIF encoding is CPU-heavy. Large images take longer on mobile. Try a lower quality setting or smaller source images.
