Add Watermark to Image

Stamp your name or logo onto any photo in seconds. Everything happens in your browser — your image is never uploaded anywhere.

Or use a logo image (PNG with transparency works best) instead of text:

Where should a watermark go?

The classic spot is the bottom-right corner — it's out of the way of faces and the main subject, and it's where viewers expect a credit line. The catch: corners are also the easiest part to remove. Anyone can crop a few percent off the edge of your photo and your watermark disappears with it. That's fine when the mark is just a polite credit, but not if you're trying to stop people from reusing the image.

For real protection, put the mark over the subject (center) or use tiled mode, which repeats your text or logo diagonally across the whole frame at low opacity. A tiled mark can't be cropped away and is genuinely hard to clone out — which is why stock photo sites use it for previews.

Corner credit vs. tiled protection

It's a trade-off between looks and security. A small corner mark at 40–60% opacity keeps the photo enjoyable and works well for portfolios, blogs, and social posts where you mainly want attribution. A tiled mark at 15–25% opacity makes the image clearly "sample only" — great for client proofs, previews, and drafts, but you wouldn't publish your final work that way. A good rule: corner for sharing, tiled for proofing. Keep the size modest too — around 4–6% of the image width reads clearly without shouting.

A watermark is attribution, not protection

Worth being straight about, because the word "protection" gets used a lot and it sets the wrong expectation. A watermark does not stop anyone taking your image. It makes taking it inconvenient and traceable, which is genuinely useful, but it is a different thing.

What a determined person can do, in rising order of effort:

None of which makes watermarking pointless. It stops casual reuse, and casual reuse is most reuse. It keeps your name attached as an image travels. And if ownership is ever actually disputed, what settles it is the original file — full resolution, metadata intact, dated, stored somewhere you control — not the mark on the copy. Watermark for credit; keep the original for proof.

Frequently asked questions

Is my photo uploaded to your server?

No. The photo and your logo are opened and combined entirely inside your browser on your own device — nothing is sent anywhere. You can even use this page offline once it's loaded.

Does adding a watermark reduce image quality?

The pixels under and around the watermark are the only ones that change. The image is re-saved once (JPEG at 92% quality, or PNG losslessly if your original was a PNG), which is visually identical to the original for normal viewing.

Can I use my logo instead of text?

Yes — pick a logo file in the "use a logo image" field and it replaces the text. A PNG with a transparent background looks best; a JPEG logo will show as a solid rectangle because JPEG can't store transparency.

White or black watermark — which should I pick?

White works on most photos because the bottom corners are often darker areas; black suits bright, light backgrounds like snow or sky. If neither stands out, lower the opacity a little and pick a busier corner — or use the color picker to match your brand.
