Can I edit existing text in a PDF for free?

Yes! PaperForge has an 'Edit PDF Text' tool that lets you click on any existing text in your PDF to modify it directly. It overlays a white mask over the original text and creates an editable text box, all 100% in your browser for free.

Is PaperForge secure? Are my files uploaded to a server?

PaperForge is 100% client-side. Your PDF files are never uploaded to any server — all editing, annotation, and export happens entirely within your web browser using modern browser APIs.

How do I add a digital signature to a PDF?

Click the 'Signature' button in the toolbar. You can draw your signature with a mouse or touch, or choose from elegant pre-designed cursive font signatures. The signature is embedded directly into your PDF when you export.

Can I add a watermark to a PDF?

Yes. PaperForge includes a Watermark tool where you can add text watermarks like CONFIDENTIAL, DRAFT, or custom text. You can control opacity, font size, rotation angle, and apply the watermark to all pages or just the current page.

Does PaperForge work on mobile phones and tablets?

Yes! PaperForge is fully responsive and optimized for mobile phones, iPads, and Android tablets. The toolbar is horizontally scrollable with touch-friendly targets, the sidebar becomes a slide-out drawer, and the signature tool supports finger and stylus drawing with zero touch lag.
