How it works

Upload your logo.
Stamp it on any photo.

Use your actual brand mark — not just text — as a watermark on any image, with full opacity and position control.

01

Open your photo

Drop any PNG, JPG, or WEBP image into the tool. It loads straight in your browser — locally, privately.

02

Upload and position your logo

Upload your PNG or SVG logo. Resize it, set the opacity, and drag it to exactly the right spot on your image.

03

Download your branded photo

Save your logo-watermarked image at full quality. Your brand is on the photo — and your files stayed entirely private.

Privacy

Your images stay
on your device.

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.

No uploads. Ever.

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.

Verified: zero network requests for images

No tracking.

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.

No cookies · No analytics · No tracking

No data stored.

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.

Data stored only in your own browser

Works offline.

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.

FAQ

Common questions.

PNG and SVG. PNG is best for logos with a transparent background. SVG scales to any resolution without becoming pixellated, which is ideal for large images.
Use the size slider to scale your logo proportionally and drag it to any position on the image. You can also use the alignment shortcuts to snap it to corners or centre.
Yes. The opacity slider lets you go from a nearly invisible 5% to a fully opaque 100%. Most professional uses sit between 30–60%.
It works best with transparency — a PNG with a transparent background will sit cleanly on any image. A logo on a white square will show the white box unless you export as PNG with alpha.
Settings persist while the browser tab is open, but are not saved between sessions. For repeated use, keeping a dedicated Watermarkerly tab open during a work session is the simplest workflow.
No. Your logo and every image you open are processed entirely in your browser. Neither file is transmitted anywhere.
Yes — completely free with no account, no subscription, and no per-image fee.
SVG is ideal if you have it — it stays crisp at any scale. PNG with transparency is the most common and fully supported. Avoid JPG for logos, as it doesn't support transparency.
