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

Krymp's watermark tool lets you add branded text or a logo overlay to any image — individually or in bulk. Adjust font size, opacity, color and placement to match your visual identity. Everything runs locally in WebAssembly so your original photos stay private.

Free for unlimited use — no account, no cap on images, no hidden watermark added on top of yours. Works on Mac, Windows, iPhone and Android.

FAQ

Can I watermark multiple images at once?
Yes — Krymp supports batch watermarking. Drop several images and the same watermark is applied to all of them.
Is my image uploaded to a server?
No. Watermarking runs entirely in WebAssembly inside your browser — files never leave your device.
Can I use a logo instead of text?
Yes. Upload a PNG logo (ideally with a transparent background) and position it anywhere on the image.
Which image formats are supported?
JPG, PNG and WebP as input. Output can be JPG or PNG depending on whether you need transparency.
Is it free?
Fully free — no account, no watermark on the watermark, no daily limit.
