Add Text Watermark to Photo — Local Browser Tool
Stamp typed text on a photo in your browser—opacity, rotation, and nine-grid position—not a logo file overlay. Steps: choose an image, enter text, tune size/color/opacity/angle, apply, download. Example: SAMPLE diagonal on a gradient — files stay on your device. For logo PNGs use Overlay Images.
How it works
Choose a photo, type watermark text, adjust style and position, apply, download.
Rules
Text is painted into pixels (not a CSS-only overlay). Anchors use relative positions; rotation is around the anchor.
- Font uses the browser default family at your size.
- Opacity applies via globalAlpha.
- JPEG export can flatten on a background color.
- Logo files belong on the Overlay Images tool.
Example
Sample places semi-transparent SAMPLE on a gradient at a diagonal angle.
Good fits
- Mark proofs as SAMPLE.
- Sign photos with a name/URL.
- Label screenshots before sharing.
