Why Watermark Before Sharing?
Once a photo is shared without a watermark, you lose attribution. It gets reposted, cropped, and used without credit. A watermark — even a subtle one — signals ownership and makes it significantly harder for others to use your work commercially without permission.
Photographers use it for client proofs. Designers use it for mockup reviews. Social creators use it for brand recognition. The tool works on any JPG, PNG, or WebP, at any resolution.
Your Photos Stay Private
Every other watermark tool on the web uploads your photo to a server. ImageXpo runs the entire process in your browser using WebAssembly. Your photo never leaves your device. Close the tab and nothing is stored anywhere.
Frequently Asked Questions
Does adding a watermark reduce image quality?
No. Only the pixels where the watermark overlaps are changed — the rest of the photo is untouched. The output is saved at the same quality as your original. There's no extra compression, no resizing, no degradation outside the watermark area.
Can I control how visible the watermark is?
Yes. The opacity slider goes from nearly invisible to fully solid. Most photographers choose something in the 30–50% range for client proofs — visible enough to mark ownership, subtle enough not to distract from the photo. You can see exactly how it looks in the live preview before downloading.
Will my photos be stored or seen by anyone?
No. The watermarking happens in WebAssembly inside your browser tab. Your photo is never uploaded, never transmitted, and never stored on any server. We have no access to your images. When you close the tab, everything is cleared from memory.
Can I watermark high-resolution photos?
Yes. There's no file size or resolution limit because nothing is uploaded. A 40-megapixel photo processes just as easily as a small one — your device handles it locally with WebAssembly. Most modern laptops and phones handle large images without any noticeable delay.
