Converting your WEBP file to AVIF happens in three steps, entirely on your device: your browser reads the WEBP file into memory, decodes and re-encodes it as AVIF using built-in browser technology (Canvas and WebAssembly), and hands you the finished file as a direct download.
At no point does the file get sent to a server. There’s no upload step to intercept, no account that could be breached, and nothing stored after you close the tab — the conversion simply couldn’t leak your file even if something went wrong, because it never left your browser in the first place.
