About the Watermark Image
A watermark marks an image as yours. It will not stop a determined person from removing it, and it is not meant to — its job is to make casual reuse obviously attributed and to make the original owner traceable when the image travels.
This stamps text across a picture, once in a chosen position or tiled across the whole surface, with control over size, colour, opacity and rotation.
Placement is the trade-off. A small mark in a corner is unobtrusive and is also the easiest thing in the world to crop out. A tiled watermark across the whole image survives cropping and is far harder to remove, at the cost of being visible over the subject. Which you want depends on whether the image is a portfolio piece being shown or a proof being sent to a client who has not paid yet — and the answer genuinely differs between those two.
Opacity does more work than size. A watermark at fifteen or twenty per cent is legible when looked for and does not fight the image; the same text at full strength ruins the picture for the person you wanted to impress. Diagonal rotation across the frame is harder to clone out than horizontal text, because it crosses more varied content.
Batch processing applies the same watermark to every image, which is the usual case for a set of proofs or a portfolio upload.
If the goal is provenance rather than deterrence, the steganography tool on this site embeds text invisibly, which survives cropping in the middle of the image and is not visible to remove.
How to use it
- 1Drop in the images to be marked.
- 2Enter the watermark text — a name, a domain, or a status such as “proof”.
- 3Choose a single placement or tile it across the image, depending on whether cropping is a concern.
- 4Set the opacity low, around fifteen to twenty-five per cent, so the mark reads without overwhelming the picture.
Questions
- Can a watermark be removed?
- Yes, with effort — cropping removes a corner mark and content-aware fill can take out a tiled one. It raises the cost of casual reuse rather than preventing determined theft, which is what a watermark has always been for.
- Corner or tiled?
- A corner mark for work you are showing off, where the image should look good. Tiled for proofs and previews, where the point is that the file is not usable until it is paid for.
- What opacity works best?
- Between fifteen and twenty-five per cent for most images. Legible when looked at, invisible enough not to fight the subject. Full opacity protects the image by ruining it.
- Is there an invisible option?
- The steganography tool on this site hides text in the image data itself, which survives cropping through the middle and cannot be seen to be removed. It is the better choice when the goal is proving ownership rather than deterring reuse.
