How can I sign a PDF document online for free without creating an account?

Upload your PDF file into RMtoolshub. Choose your preferred signature method: Draw your signature with a mouse/stylus, Type your name using handwritten fonts, or Upload a transparent PNG. Select your target page, click 'Add Signature to PDF', drag the signature to your signature line, resize it using the corner handle, and download your signed PDF immediately.

How do I add a 'CONFIDENTIAL' or custom logo watermark to all PDF pages?

Switch to the 'Watermark' tab, enter your custom watermark text (or upload your company PNG logo), adjust the opacity slider, angle, and font size, and click 'Apply Watermark'. The watermark applies uniformly across all pages with zero watermark branding from RMtoolshub.

Are my legal contracts, NDA documents, or signatures uploaded to any server?

No. All PDF page parsing and cryptographic vector modifications execute strictly inside your local browser memory using PDF.js and pdf-lib. Your confidential documents and signatures never leave your device.

Can I both sign and watermark a PDF file at the same time?

Yes. You can add a signature to a specific page and apply a text or logo watermark across all pages in the same session, then download the combined document in a single click.
