BEFORE YOU BEGIN
A little clarity goes a long way.
What kinds of watermarks can be removed?
Structured watermarks: text drawn the same way on several pages, repeated images, optional-content layers, and stamps. Watermarks merged into a scanned page are a different problem and are not supported yet.
Are my documents stored in my account?
PDFDew does not upload or store your original PDF. If local detection is uncertain, candidate labels and up to three rendered page previews may be sent to DeepSeek for analysis. Use Local mode when no document content may leave your device.
Do I need a paid plan?
No. Single-file and Local structured watermark removal run on your device for free. Starter adds AI-assisted analysis, batch processing, and the PDF editors.
