Adds a text watermark to JPG / PNG / WebP images
About this tool
Shared pictures get reposted - a text watermark is the lightest way to sign your work and raise the cost of theft. This tool offers two modes: tiled, which repeats your text across the whole picture at the angle you pick and makes cleanup expensive, and single, which places one watermark in a corner or the centre for a quiet credit. Size, color, opacity and rotation are all adjustable.
Watermark text is rendered with your browser fonts, so Chinese, English and emoji all display correctly. A watermark is visible content: it deters casual reposting but determined editors can remove it, so keep the original file for anything that matters. Everything runs locally - images are never uploaded.

Frequently asked questions
- How do I cover the whole image with the watermark?
- Choose the tiled mode: the text repeats across the picture at your chosen rotation (-30° is the classic). Spacing is derived from the text size automatically; 20%-40% opacity gives a visible-but-not-intrusive result.
- Can the watermark be removed?
- It is visible pixels - ordinary editing cannot strip it with one click, but skilled retouching can weaken or remove it. Watermarks raise the cost of casual theft rather than providing strong protection; keep your originals for enforcement.
- Does watermarking reduce image quality?
- The picture is re-encoded once in the chosen format: JPG/WebP at the default 90% quality is visually indistinguishable; PNG is lossless but larger. Pick WebP for the smallest output.
- Does the watermark support Chinese characters?
- Yes. Text is rendered by your browser fonts, so Chinese, English, Japanese and emoji all display correctly - nothing to download or install.
