What is Image Watermarker?

A watermark is a semi-transparent text or logo overlay placed on an image to identify the creator, prevent unauthorized use, and deter content theft. Photographers watermark portfolio images before sharing so work cannot be used without attribution. Businesses overlay logos on product preview images to maintain brand visibility. Document watermarks (CONFIDENTIAL, DRAFT, SAMPLE) communicate status visually.

This browser-based watermarker overlays text (custom font, size, color, opacity) or an image (your logo file) onto a source image. Position at corners, center, or custom coordinates. Set opacity from 10% to 100% — 30–50% gives a visible but non-intrusive mark. Neither the source image nor the watermark file is uploaded to any server — all processing runs in the browser.

Image Watermarker FAQs

Quick answers about the workflow, privacy, and where this tool fits in a broader job.

What opacity should I use?

30–50% opacity makes the watermark visible but keeps the image readable. For promotional previews where deterring downloads matters, 60–80% is more effective. For attribution-only marks on public images, 20–30% is subtle.

Will the watermark be removable?

Any watermark can be removed by skilled editors. The goal is deterrence and attribution. Center watermarks overlapping the main subject are harder to remove than corner watermarks, which can simply be cropped.

Can I batch watermark multiple images?

This tool processes one image at a time. For batch watermarking, desktop software like Photoshop (batch actions) or ImageMagick command-line is more efficient.
