💧 Why add a watermark?
A watermark overlays your name, business, or social handle onto a photo to deter unauthorized use and mark ownership. It's widely used for blog photos, product images, portfolios, and ID/document copies submitted for verification.
🛡️ Tips for an effective anti-theft watermark
- Turn on tile repeat to scatter the text across the whole photo, making it harder to crop out.
- Lowering opacity to 20–40% keeps the mark visible without obscuring the photo too much.
- Placing it over an important part of the subject (a face, logo) makes cropping it out harder.
- Upload multiple images to apply the same watermark to all of them at once — handy for bulk work.
🪪 Marking ID or document copies
When submitting an ID or bank statement copy, overlaying text like "For [purpose] only" reduces the risk of it being reused elsewhere. Everything runs in your browser only, so sensitive copies are never sent to a server.
💧 Placement strategies
Where and how you place the watermark changes its effect.
| Placement | Effect & use |
|---|---|
| Large, single spot | Copyright or source mark — center or a prominent area |
| Tiled repeat | Anti-theft — repeated across the image so it is hard to crop out |
| Small, in a corner | Branding — a clean finish that does not disturb the image |
| Opacity guide | 10–20% for readable documents; 30–50% for theft protection |

💬 Frequently Asked Questions
- Can I repeat the watermark across the whole photo?
- Yes. Turn on "Tile repeat" and diagonal text is repeated across the entire image — effective against unauthorized use.
- Can I adjust opacity and color?
- Yes. Freely adjust text size, opacity, color, rotation, and position, and check the result in a live preview.
- Can I apply it to multiple photos at once?
- Yes. Upload several images and the same watermark is applied to all of them, downloadable in one batch.
- Can I add an image (logo) watermark?
- Only text watermarks are supported for now — text, font, color and rotation are all adjustable.
- Can a watermark be removed later?
- The watermarked file saves as a new file and the original stays unchanged. Keep the original to redo it anytime.
