About Add Watermark
Protect your creative work with a professional text watermark. CocoConvert renders your custom text directly onto the image pixels — it becomes a permanent part of the file, making it impossible to remove without visible traces. Choose from 5 positions (center, corners), 4 sizes, 4 colours, and adjustable opacity (10-100%).
For photographers sharing proofs, designers posting portfolio samples, or businesses distributing branded materials, batch watermarking is a game-changer. Pro users can watermark up to 100 images in a single batch — upload your entire shoot and have every photo branded in seconds.
The watermark text is sanitised to prevent SVG injection and encoded safely into an SVG overlay composited at render time. This means your text can include accented characters, CJK scripts, and symbols without breaking.
Every image is processed in an isolated sandbox, never stored beyond 24 hours, and never analysed. No account needed.

Frequently Asked Questions
Can the watermark be removed?
The watermark is rendered directly into the image pixels — it is permanent. It cannot be removed without visible traces or photoshop-level editing.
Can I batch watermark multiple photos?
Yes! Pro users can watermark up to 100 images at once with identical settings. Perfect for photography proofs.
Does watermarking reduce image quality?
No. The image is re-exported at high quality (95%). The only change is the addition of the watermark overlay.
