Security & Privacy

The ultimate watermarking tool for professionals.

Protecting your photographic work is essential to defending intellectual property. Photographers, content creators, e-commerce businesses and agencies need to apply watermarks quickly and safely to prevent unauthorized use of their images online. Our tool is designed to simplify this process, making it instant and accessible to everyone.

Total GDPR Security

We never send your photos to any external server. The entire watermarking process happens locally within your computer's temporary memory, guaranteeing total confidentiality.

Unmatched Local Speed

Forget long waiting queues or upload bandwidth limits. Thanks to HTML5 Canvas processing, watermarking and downloading 100 photos in a ZIP archive takes only a few seconds. And it's precisely because your browser does all the work, without ever touching our servers, that we can offer unlimited bulk processing for free — unlike many online tools that reserve it for paid plans.

Our technology guarantees unprecedented processing speed thanks to a 100% client-side approach. No photo is uploaded to external servers: processing happens entirely locally in your browser. This ensures absolute privacy for your files and full GDPR compliance.

Upload dozens of high-resolution photos, position your logo, adjust the transparency and apply the watermark to all images at once. Keep your copyright safe, simply and quickly.
