Note: The tool UI is in Swedish, but the workflow is purely visual — drag, pick a level, download. File processing is identical.

Krymp compresses images locally using WebAssembly. Photos shrink 40–70 % without visible quality loss; PNGs with transparency typically save 20–40 %. Everything runs on your device, so confidential screenshots, ID documents and product photos stay private.

Free for unlimited use — no daily caps, no watermark, no account. Works on Mac, Windows, iPhone and Android in any modern browser.

Private. Files are processed in your browser. Nothing is uploaded.
