About us

Tool is a set of image utilities that run in your browser. Resize, convert, or watermark without first uploading photos to an unknown server.

Why browser-side processing

Modern browsers ship Web Workers, Canvas, and WASM capable enough for everyday encode/decode work. Local processing means lower privacy risk and less round-trip delay, and we do not need a heavy image farm. The trade-off is that device performance affects large batches — we surface that honestly in the UI.
