How it works

Protect your shots.
Before they leave your hands.

Designed around the photographer's workflow — from card to share without a single upload.

01

Open your photo

Drag & drop straight from your memory card or camera roll. PNG, JPG, or WEBP — loads instantly right in your browser. Nothing leaves your device.

02

Add your copyright mark

Type your name or studio, or upload your logo. Adjust font, size, opacity, and placement until it matches your brand exactly.

03

Download at full resolution

Save your watermarked photo directly to your device as a PNG or JPEG. Full quality, zero compression — ready to share or archive.

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.

No. Watermarkerly exports your watermarked image as a full-resolution PNG or JPEG — zero recompression beyond what the export format requires. Your original file is never modified.
Yes. Type any text you like — © 2026 Your Name, your studio name, your website — and style it with your preferred font, size, and opacity.
Yes. Open JPG or PNG files directly from your memory card or camera folder. Everything processes locally, so even large full-resolution RAW exports (converted to JPEG) work without slowdown.
Most photographers use the lower-right corner at around 25–35% opacity for a visible but non-intrusive mark. For sharing proofs, a tiled or centred watermark at higher opacity is more protective.
Yes. Batch mode lets you drop a full folder and apply your watermark to every image, then download them all in a single ZIP — all processed locally.
Never. There is no server involved. Your images are processed using the HTML5 Canvas API entirely in your browser. Open DevTools and check the Network tab — you'll see zero image uploads.
Yes — completely free with no usage limits, no account required, and no 'Watermarked by Watermarkerly' branding added to your output.
