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 to H.264 at a constant quality level. Unlike a fixed target size, constant quality spends bits where the picture needs them — a static talking head ends up far smaller than an action scene at the same setting.
