Your files never leave,
only the marks do.

No account, no upload queue. Done in three steps.

Restore to fit the format

A dedicated engine for videos, documents, and images handles the watermark area.

Creates the output right on your device instead of an expiring external link.

NOTES / FAQ

Questions about this format

Are files uploaded to a server?

No. Every processing engine and all file data run inside your browser.

Can I still edit the slides in PowerPoint?

Yes. Text, shapes, and layout are untouched — only the images inside the file are cleaned.

What exactly changes in the file?

Only the raster images under ppt/media that carry the watermark; the rest of the .pptx is preserved.

Does it re-compress the whole presentation?

No. It only rewrites the affected images and repackages the archive.
