Nothing is uploaded. Your files are decoded, converted and re-encoded by WebAssembly running inside this tab, then handed straight back to you. The first conversion of a kind downloads that engine (a few MB for images, ~12–30 MB for video/audio) — later ones are instant.
Your files never leave this device — there is no upload and no server to delete them from.
About this tool
Re-encodes each image with MozJPEG, oxiPNG or the WebP encoder at the quality you choose. Format stays the same, so links and filenames keep working — only the bytes change.
