Can I adjust the transparency of my watermark?

Yes, you can easily control the opacity to make the watermark subtle.

Is this secure for pre-release photos?

Yes, because the watermarking happens entirely in your browser. The photo is never uploaded anywhere.

Is it safe to use Edita for sensitive files?

Absolutely. Edita processes all your files locally in your browser using WASM (WebAssembly) technology. Your documents never leave your device and are never uploaded to our servers, ensuring total privacy.

Does Edita store my data or file history?

No. We have a strict 'no-storage' policy. Once you close your browser tab, all traces of your processed files are gone. We don't track your content or keep any logs of your file data.

Why is Edita faster than other online converters?

Traditional tools require you to upload large files to a server, wait for processing, and then download them back. Edita eliminates all network lag by processing everything instantly on your own hardware.

Secure & Fast Add Watermark in Your Browser

Format incompatibility slows digital workflows down. Edita's browser-based Add Watermark tool lets you convert, adapt, and process your files without uploading them to any third-party server. All processing happens locally using WebAssembly — delivering the speed of a desktop application with the convenience of a browser tab.

Why Edita Handles Files Better

By running file operations through WebAssembly in your browser, Edita keeps your data strictly on your device. Your files are processed using your computer's own CPU — never transmitted, never stored, never seen by any server. There's no upload queue, no server lag, and no artificial file size limit.
