Convert to WebP
Re-encode images as WebP, typically 25–35% smaller than JPEG.

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
WebP handles photographs and flat graphics well, keeps transparency, and is supported by every current browser. A good default for anything going on a website.
