Why convert WebP to AVIF?
Both WebP and AVIF use either lossy or lossless compression, depending on settings, so the conversion mainly changes compatibility, not quality. The main reason to convert WebP to AVIF is compatibility: AVIF opens in every browser, image viewer and design tool without a plugin, while WebP doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, AVIF is usually the safer target.

Will I lose quality converting WebP to AVIF?
AVIF is next-gen format with the best compression available today, growing browser support. We use the highest-quality encoder settings by default so visual or data loss is minimized.

No, not by default. You choose a retention window at upload — immediate, 1 hour, 24 hours or 7 days — and the file is permanently deleted after that.
What is WebP?
Modern format with smaller file sizes than JPEG or PNG at equivalent quality.
