What does this tool do?
This free watermarking tool adds a text or logo watermark to your images in seconds — choose any corner, center, or a repeating tiled pattern, and control the font size, color, rotation, and opacity. The watermark is rendered locally in your browser, so your originals stay on your device.
How does the image watermark work?
Watermarks are composited on a Canvas: text is drawn with your chosen font, size, color, and globalAlpha opacity; logo watermarks are drawn as scaled overlays. Tiled mode repeats the mark diagonally across the whole image — the most effective protection against cropping it out.
Frequently Asked Questions
Where is the best place to put a watermark?
For real protection, tiled diagonal watermarks across the whole image are hardest to remove. For aesthetics, a corner mark at 40–60% opacity signals ownership without ruining the photo — but corners are easily cropped. Many photographers compromise: subtle center-third placement over a busy area.
Does a watermark legally protect my image?
Copyright exists automatically when you create an image — watermark or not. But a watermark provides visible attribution, deters casual theft, and matters legally: removing a watermark to hide infringement can trigger extra damages under laws like the US DMCA §1202. Keep your unmarked originals as proof of ownership.
Is the watermark tool really free?
Yes — 100% free with no hidden charges, trial limits, or premium tiers for core features. No account or email needed. The site is supported by non-intrusive display ads, which keeps every tool free for everyone.
Are my files private when using the watermark tool?
Completely. The watermark tool processes everything locally in your browser — your files are never uploaded to any server. When you close the tab, everything is gone. This makes it safe for confidential documents, client work, and personal photos.
Does the watermark tool work on mobile phones?
Yes. It's built mobile-first and works on any modern phone browser — iPhone (Safari) and Android (Chrome) included. You can pick files straight from your camera roll and download results directly to your device.
Do I need to install any software to use the watermark tool?
No. The watermark tool runs entirely in your web browser — no downloads, extensions, or signup. Open the page, use the tool, download your result. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
