How to watermark photos online — free, no upload

Add the same text watermark to one photo — or hundreds at once — in three simple steps, right in your browser. No sign-up, no software to install, and your photos never leave your device.

Watermarking is how you keep your name on your work: photographers credit their shots, small businesses brand product photos, and anyone sharing documents or screenshots can mark them confidential or sample. The problem is that most watermark tools make you edit photos one at a time, force an upload to someone's server, or hide the download behind a paywall.

Inkso does it differently: place one watermark, and it's applied to every photo you've added — automatically.

Watermark your photos in three steps

1. Add your photos

   Open the free watermark tool and drop your images anywhere on the page — one photo or a whole shoot at once. JPG, PNG and iPhone HEIC photos all work. Each photo appears in a filmstrip so you can flip through them.

2. Type and place your watermark

   Type your text — your name, brand, or © notice. Pick the font, make it bold or italic, add a ©, ® or ™ symbol, and set the colour, transparency and angle. Then just drag it where you want it and resize it with the corner handle. Want all-over protection? One click on Tile repeats it across the whole image.

3. Download

   Click Download. One photo saves as a single file; a batch saves as a ZIP with every photo watermarked. That's it — no account, no watermark on the watermark, no fee.

Built for batches: hundreds of photos in one go

This is the part that saves real time. You don't place a watermark on each photo — you place it once, and Inkso applies it to every image you've loaded. The position and size are stored proportionally, so the watermark lands in the same spot at the same relative size on every photo, whether it's a wide landscape, a square product shot, or a vertical phone picture.

• No per-photo editing — style it once, download all.
• Mixed sizes are fine — the watermark scales to each image automatically.
• One ZIP — a batch downloads as a single ZIP file, named and ready to share.
• Live preview — what you see on screen is pixel-for-pixel what you download.

Add a copyright © symbol to a photo

A proper copyright notice — © symbol, year, your name — is the clearest way to claim a photo as yours, and Inkso has it built in. Type your name as the watermark text, then click the © button in the toolbar (® and ™ are there too). You can attach the symbol at the start or the end of your text, and one more click makes it smaller and raised — the classic superscript look. The symbol automatically takes on the same colour and transparency as your text, so it always looks like one clean mark. Like everything else, it's applied to every photo in your batch at once.

Add a handwritten signature to your photos

Next to Watermark you'll find Signature mode: draw your signature once with your mouse, trackpad or finger, straight onto the photo — and it appears on every photo you've loaded, scaled to fit each one, just like the watermark. Choose the stroke style (pen, marker, pencil or calligraphy), the colour, the thickness and the transparency; Undo removes the last stroke if it goes wrong. It's the artist's way to sign a whole set of work in one go — and you can combine it with a text watermark on the same photos.

Your photos never leave your device

Everything — loading, watermarking, zipping, saving — happens locally in your browser. Your photos are never uploaded to a server, so there's nothing for anyone to store, scan, or train AI on. Close the tab and they're gone. That also makes it fast: no waiting for uploads and downloads of big image files.

Tips for a watermark that protects without ruining the photo

• Keep the transparency around 40–60% — visible enough to deter copying, subtle enough not to distract.
• Use Tile for photos you're posting publicly — a repeated watermark is much harder to crop or clone out than a single corner mark.
• Add the © symbol with the year and your name (e.g. “© 2026 Jane Doe”) — it signals ownership at a glance.
• A slight angle (30–45°) makes the watermark harder to remove automatically.
