Frequently asked questions

Can I place the watermark in one spot instead of diagonally?

This tool places the watermark diagonally across the entire image for maximum protection. For a small watermark in a fixed corner, use the add text tool with a transparent colour setting.

Can I adjust the size and transparency?

Yes, you can set the text size, colour and opacity. A semi-transparent white watermark is the most commonly used setting for portrait and product photos.

Does a watermark really protect my photo?

A watermark makes unauthorised use visible and discouraging, but can be removed by advanced users with editing software. It is a clear ownership signal, not an unbreakable protection.

What are watermarks used for?

Photographers watermark preview images they send to clients. Designers protect portfolio images. Businesses mark stock photos or promotional material with their brand name.

Is my image uploaded?

No. Everything happens in your own browser. Your image never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free, without watermark or account. The site is paid for by ads.

Why in the browser?

PixRust runs entirely in your browser using the Canvas API and WebAssembly. Your image is never sent to a server — all processing happens locally on your device. This means your photos remain private by design, whether they are personal snapshots or confidential documents. There is no account required, no file size limit, and nothing is stored after you close the tab.
