Can the watermark be removed?

From an image, only by retouching, which leaves traces at 30 percent opacity across the whole picture. From a PDF, with an editor and effort; it is a deterrent, not encryption.

Does it support diacritics?

On images, any text. On PDFs the embedded Helvetica covers Western letters; ă, ș, ñ are replaced by their base letter.

Is the file uploaded?

No. Images are stamped on a canvas in your browser and PDFs are rewritten locally.

Watermark photos and documents before sharing

Updated October 29, 2026

Sending a scan of your ID to a landlord or a bank is normal; sending it with nothing written on it is how that scan ends up reused somewhere else. A visible watermark with the purpose and the date makes the copy useless for anything else.

The same trick marks drafts, proofs and photos you do not want reused. The watermark tool stamps text on images and on every page of a PDF, on your device.

ID scans: write the purpose on them

Choose "tile" position, 30 to 40 percent opacity and a text like "Copy for ACME rental contract, 12 March 2027". The text crosses the whole document, including the photo and the numbers, so it cannot be cropped out, yet everything stays readable.

Many institutions ask for exactly this; the rest accept it without comment. Keep the opacity low enough that the machine-readable zone stays legible.

Drafts and proofs

A large diagonal "DRAFT" or "NOT FOR DISTRIBUTION" at 20 percent opacity in the centre of each page prevents a working version from being mistaken for the final one. For a client proof of a design, use your studio name tiled at low opacity.

Photos

For a batch of photos, drop them all at once: the same text goes on each at the same relative size. Corner placement is enough when the point is attribution, not protection; tiling is for images you expect to be copied.

Tips

Dark text on light scans, light text on photos: pick the colour that stays visible.
Compress the watermarked PDF afterwards if it goes by email.
The watermark is drawn into the pixels (images) or as page content (PDF); it cannot be switched off by the recipient.
