The completely free, privacy-first online tool that lets you add professional watermarks to your images — instantly and securely.
Watermarks.Online was born from a simple frustration: most watermark tools either cost money, require registration, upload your images to unknown servers, or produce low-quality results.
We believed there should be a better way — a tool that's truly free, respects your privacy, and delivers professional-grade results without any compromises.
So we built it. A modern, client-side watermarking app that runs entirely in your browser. No uploads. No accounts. No limits. Just fast, beautiful watermarks whenever you need them.
Your images never leave your device. All processing happens locally in your browser — giving you complete control and peace of mind.
No subscriptions, no hidden fees, no "premium" features locked away. Everything is 100% free, forever.
Professional features like batch processing, pattern modes, logo support, and full customization — with instant results and no waiting.
Works on any device, any browser, anywhere in the world. No installation required.
Join thousands of photographers, designers, and creators who trust Watermarks.Online every day.
Start Watermarking Now →In an age where images are shared instantly across the internet, protecting your creative work has never been more important. Yet many creators — especially independent photographers, artists, and small businesses — can't afford expensive software or don't trust cloud-based tools with their original files.
Watermarks.Online exists to level the playing field. We want every creator to have access to professional-grade protection tools without sacrificing privacy or paying premium prices.
We're committed to keeping this tool free and improving it based on your feedback. Have a suggestion? We'd love to hear it on our Contact page.
