Watermark Image
Corner or tiled — the only decision that matters
A watermark in the corner is polite and nearly useless: it crops off in one move. A watermark tiled across the whole picture is genuinely awkward to remove, because taking it out means reconstructing what is underneath it everywhere. The cost is that it sits between the viewer and the photograph.
Most people want the corner for a portfolio and the tile for proofs and previews — the versions sent to a client before payment. Both are here; the trade-off is real and there is no setting that avoids it.
Making it readable on any photo
White text vanishes on a bright sky and black text vanishes in shadow. The shadow option draws a soft dark edge behind the mark so it stays legible over both, which is why it is on by default. Around 30 to 40 percent opacity is usually enough to be clear without dominating.
Size is a percentage, deliberately
A watermark set in pixels looks right on one photo and wrong on the next. Here the size is a share of the image, so the same setting carries over from a phone snap to a 24 megapixel file.
What this is not
It is a visible watermark, drawn into the pixels. There is no hidden or forensic mark, no embedded identifier, and nothing that survives someone painting over it. Anyone claiming a web page can add theft-proof protection is overselling it.

Frequently Asked Questions
No. The image is drawn onto a canvas in your browser and saved from there. Nothing is sent to a server, which matters when the thing you are marking is an unpublished photograph or a document.
It raises the effort, nothing more. A corner mark can be cropped off in seconds and a faint one can be painted out. A watermark tiled across the middle of the picture is far harder to remove, at the cost of being harder to look past — that is the real trade-off, and it is yours to make.
Because the size is set as a share of the image, not in pixels, so the same setting looks the same on a phone snap and a 24 megapixel file. Raise the size slider rather than expecting a fixed number to suit every picture.
Yes. A PNG with a transparent background works best; anything else keeps its own background, which usually looks wrong over a photo.
A visible watermark does, because it is part of the pixels. It is not an invisible or forensic watermark, and it carries no hidden data — it is exactly what you see.
The image is re-encoded, and a photo re-saved as JPEG at high quality can come out larger than a well-optimised original. Lower the quality slider if size matters.
