Understanding Image Watermarking

Protect Your Work

Add a visible copyright or attribution mark to photos before sharing them online.

Adjustable Opacity & Position

Choose how prominent the watermark is and which corner (or center) it sits in.

Custom Text

Use your name, brand, website, or copyright symbol — any short text works as a watermark.

Local Processing

Watermarking happens entirely in your browser using the Canvas API — your image is never uploaded.

Watermarks Are a Deterrent, Not a Lock

A visible text watermark discourages casual reuse and signals ownership, but it can be cropped or edited out by a determined user — it isn't a substitute for proper copyright registration or licensing terms if you need enforceable protection.

Key Takeaways

Custom Text & Position: Place your watermark text in any corner or the center of the image.
Adjustable Opacity: Balance visibility against how much the watermark distracts from the photo.
Client-Side Only: All watermarking happens locally in your browser — no data is ever sent to a server.
