WaterMarker Pro
durch NKB Solutions
Add watermarks to images directly in your browser — 100% private, no server uploads.
Watermark your organisation’s images without leaving SharePoint — and without uploading a single file to any external service.
WaterMarker Pro is a fully client-side watermarking tool embedded directly in a SharePoint page or Teams tab. Users drag in images, configure a text or logo watermark, preview the result live, and download the finished images — all in the browser. Nothing ever leaves the device.
Licence requirement: In order to use this app, a WaterMarker Pro licence is required. A 30-day free trial is available. Licences and trial requests can be submitted via the contact form at www.nkbsolutions.nl/contact or by emailing contact@nkbsolutions.nl.
