to add a watermark
Protecting digital photography, graphic designs, and portfolio previews from unauthorized commercial scraping or copyright infringement requires visible attribution. ImageUp provides live in-browser watermark compositing with custom typography, transparent PNG logo overlays, 9-point grid positioning, opacity blending, and full-frame tiled pattern repeat modes.
Select the photo or artwork you wish to protect with a watermark.
Choose Text (custom message, font size, color, opacity) or Logo (upload PNG icon, scale slider).
Select a 9-point anchor position or toggle full-frame Tiling, preview live changes on canvas, and download.
Easily switch between custom copyright typography and transparent high-resolution brand logo marks.
Repeats your watermark in a diagonal repeating grid across the entire photo to prevent crop-out theft.
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 work online invites copying, and a watermark keeps your name attached to it. This tool stamps photos with a copyright notice or brand logo, whether you're a photographer sending proofs or an artist posting to social.
Attribution is fully controllable: custom text, font color, and opacity for a clean look, or a transparent PNG logo for a professional touch. Place it in any corner, or tile it across the image so cropping it out is impractical.
Processing happens locally, so uncompressed masters never upload and never degrade through a cloud's compression. Stamping is instant and free.
