Image Watermark

Yes. 100% free, no signup, no watermark on output, no daily limit. Add text to as many images as you want.

Yes. Type your text in the Text Content box and press Enter for a new line. Each line is rendered with the chosen font, size, color, and style. Multi-line text is positioned as a single block at your chosen position — so the whole block stays correctly centered, top-aligned, or bottom-aligned.

When you enable "Tile / Repeat Watermark", your text is drawn in a grid pattern across the entire image, then the whole grid is rotated by the tile angle (0-90°) around the image center. The text repeats at ~200px spacing (scaled with font size) so it covers the whole image — perfect for protecting stock photos, design proofs, or any image you want to credit. Tile alpha is auto-capped lower (~30-60%) so the watermark does not overpower the underlying image.

No. All text rendering happens in your browser using the HTML5 Canvas API. Your image is never uploaded to any server. Everything is computed locally on your device.

To keep the tool fast and crash-free on phones and tablets. Images larger than 4096px on the longest side are scaled down proportionally before text rendering — the text overlay is fully preserved. Canvas processing is wrapped in try/catch so any error (tainted canvas, OOM, etc.) is silently ignored.
