Protect your art from theft before posting online. Nothing leaves your device.
Add your artist signature or logo to any digital artwork right in the browser. No server, no upload, no account — just open and protect your work.
How it works
Add your artist signature or logo to your work before posting anywhere — your artwork stays entirely on your device.
Load your digital painting or illustration directly — large high-resolution canvases work without any upload or server.
Type your name or upload your artist logo. Set opacity for a subtle mark or a bold statement — full control.
Export your watermarked artwork at full resolution. Post to ArtStation, Behance, or social — protected and signed.
Privacy
Most tools upload your photos to a server. We don't — because there's no server to upload to. Everything runs locally, right in your browser.
Your photos are processed using the HTML5 Canvas API — entirely in your browser's memory. They never touch a server, never transit a network, never leave your machine.
We use zero cookies. No analytics scripts watching what you do. No fingerprinting. No ad networks. We genuinely don't know who you are — and that's the point.
We store nothing about you or your images — not on our servers, not in any database. Your watermark text preference may be saved in your own browser's LocalStorage, which only you can access.
Once the page loads, you can disconnect from the internet entirely. Watermarkerly keeps working. It's just your browser and your files — no dependency on any external service.

Features
Built for photographers, creators, and anyone who wants to protect their work without jumping through hoops.
No upload wait times, no server queues. Your image is processed locally the instant you make a change — preview updates are real-time.
Privacy isn't a marketing claim — it's the architecture. With no server to send data to, your images literally cannot be accessed by anyone but you.
Open the tool and start immediately. No email, no password, no subscription tier to choose. We don't even want your data — that's the whole point.
Once the page loads, disconnect from the internet. Watermarkerly keeps working, because it doesn't need a connection to do its job. Full offline capability.
