Fine-tune opacity from subtle semi-transparency (15%–30%) up to full solid opacity with real-time canvas rendering.
An opacity between 25% and 40% is ideal for maintaining clear brand visibility while ensuring the viewer can still appreciate the underlying artwork.
Yes! Switch to the 'Image' tab, upload your brand logo (PNG with transparent alpha channel recommended), and adjust the scale slider to size it relative to your base photo.
Watermarks placed only in corner positions can easily be cropped out by unauthorized downloaders. Tiling repeats your watermark across the entire image surface, making removal virtually impossible without destroying the photo.
No. All watermark compositing, text rendering, and PNG blending occur strictly in your browser tab via HTML5 Canvas 2D context with 100% offline privacy.
Sharing your creative work online is essential for building an audience, but it also opens the door to unauthorized copying and image theft. Our watermarking tool helps you protect your intellectual property by letting you quickly stamp your photos with a custom copyright notice or your personal brand logo. Whether you are a professional photographer sharing client proofs or a digital artist posting to social media, adding a watermark ensures your name stays attached to your creations.
You have full creative control over how your attribution appears. If you want a clean and simple look, you can type in custom text, pick a font color, and adjust the opacity so it blends naturally into the background. For a more professional touch, you can upload a transparent PNG of your own logo. You can place the watermark neatly in any corner, or use the tiling feature to repeat your logo across the entire image, making it incredibly difficult for anyone to crop it out.
Because you are dealing with high-resolution original files, privacy is incredibly important. Our tool processes everything locally on your device, meaning your uncompressed master photos are never uploaded to a remote server. You do not have to worry about quality degradation from cloud compression or someone intercepting your files. The entire stamping process happens instantly in your browser, giving you a secure and completely free way to protect your digital portfolio.
