Add a Text Watermark to PNG
Drop PNG files (or JPG / WebP) and stamp the same text watermark on each — DRAFT, © your name, your handle, a URL. Pick a position (centre or one of four corners), font size, colour, and opacity. Same text and styling applied to every file in the batch.

Common settings
- DRAFT stamp: centre · 120 px · red or grey · opacity 0.3.
- Photo copyright corner: bottom-right · 24 px · white · opacity 0.7 with shadow (not configurable here — pick a contrasting colour).
- Brand handle: bottom-right · 16–24 px · white · opacity 0.6.
- "PROOF" / "SAMPLE": centre · 80 px · red · opacity 0.4. Easier to remove than DRAFT, deliberately.
- Heavy anti-theft watermark: centre · 100 px · brand colour · opacity 0.5. Crops would be obvious.
Watermarking is deterrence, not security
A text overlay can be cropped out, painted over, or in some cases AI-removed. It signals ownership and discourages casual reuse — it doesn't prevent theft. For real provenance, use C2PA / digital signatures (out of scope here).
Tips for making the watermark readable
- Contrast matters more than colour. White on dark, dark on light. Picking the "right brand colour" is secondary.
- Opacity 0.3–0.5 for centre overlays. 0.5–0.8 for corner attribution.
- Font size scales with image. 24 px on a 1080 image is small. On a 4000 px photo, use 60+.
- Don't put it where it disappears. Bottom-right on white-skies sky photos vanishes. Pick centre or use a contrasting colour.
FAQ
Does the tool add its own branding to my image?
No. The only mark on the output is the text you type — there's no app logo, no "made with" stamp, and no ads. Files are watermarked in your browser and never uploaded, so unreleased photos stay private.
Logo / image watermark instead of text?
Not in this tool — text only. For an image overlay, two-step: composite externally (or use Sprite sheet with the photo + the logo as the second cell), or use a desktop editor.
Why does my white watermark disappear on a white background?
White-on-white. Pick a contrasting colour, lower opacity won't help. For mixed backgrounds, corners with predictable colour tend to work best.
Tiled / diagonal watermark?
Not yet — single position only. For a heavy anti-copy mark, use the centre position with high opacity.

Every network crops differently. Start from the size chart rather than guessing and reposting.

Part of: Build a starter brand kit from one logo
Everything downstream wants a different shape of the same mark. Make the square master once and derive the rest from it.
