Protect your photos in seconds. Your files never leave your device.
Add custom text or logo watermarks to any image — right in the browser. No account, no server, no data collected. Ever.
How it works
No learning curve. No settings to configure. Just open the tool and go.
Drag & drop or click to open any photo — PNG, JPG, WEBP, or GIF. It loads instantly right in your tab. Nothing is sent anywhere.
Type your text or upload a logo. Adjust size, opacity, rotation, and position with simple controls. Preview updates live.
Hit download. Your watermarked image saves directly to your device as a PNG or JPEG. Full quality, zero compression.
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.
