Stamp a Text Watermark Across Your Images
Overlay your own wording in a chosen position, size, colour and opacity — including a tiled diagonal pattern.
About the Watermark Image Tool
Type the text you want and choose where it sits: any of the four corners, the centre, or tiled diagonally across the whole frame. Size is set as a percentage of the image width, from 1 to 20 with 4 as the default, which keeps the mark proportionate whether it lands on a small web image or a full-resolution export. Colour and opacity are separate controls, the latter running from 5 to 100 percent and starting at 55, so the mark can sit anywhere between a faint tint and fully solid.
The tiled option is the one to reach for when the goal is deterrence rather than attribution. A single corner mark can be cropped away in seconds; a diagonal repeat covering the entire picture cannot be removed without destroying the image underneath it. Marks are applied in your browser, which matters when the work being protected has not been released or paid for yet.
Key Features
- Six placement options: Four corners, dead centre, or a diagonal tile that repeats across the whole image.
- Size relative to width: Setting the size as a percentage keeps the mark proportionate across images of different resolutions.
- Independent opacity: Opacity from 5 to 100 percent lets the mark be subtle enough to read past, or emphatic enough to deter reuse.
- Any colour: A picker sets the text colour so the mark can be light on dark photographs or dark on pale ones.
- Legible on busy images: Corner and centre marks carry a soft shadow so they stay readable over a light or cluttered background.
How to Use the Watermark Image Tool
- Add the images you want to mark.
- Type your watermark text — the tool will not run with the field empty.
- Choose a position, then set size, colour and opacity while watching the preview.
- Pick tiled if the mark needs to survive cropping, then export.
How It Works
The mark is drawn as canvas text in a bold weight, sized at your chosen percentage of the image width with a floor of 12 pixels so it never becomes illegible on small files. Corner and centre placements are inset by a padding derived from the font size and given a soft drop shadow to hold up against a light background. The tiled mode rotates the canvas by thirty degrees and repeats the text on a grid whose spacing is calculated from the measured text width. Two things to be aware of: this stamps text only, so a logo image cannot be used as the mark, and the result is a visible overlay rather than an invisible forensic watermark — it deters casual reuse but is not a cryptographic claim of ownership.
When You Need It
An illustrator sends concept artwork to a client for approval before the invoice is settled. Marking each piece diagonally across the whole frame means the roughs can be reviewed and circulated internally without being usable as finished assets. The artwork is unreleased commissioned work, and uploading it to a watermarking site would put an unpaid commission on somebody else's server — the precise scenario the watermark exists to guard against. Photographers issuing proofs and consultants circulating draft plans mark their files for the same commercial reason.
