❓ Frequently Asked Questions
Are all PDF editing tools truly free with no limits?
Yes — every tool on this page is 100% permanently free. No sign up, no account, no subscription. You can use any tool unlimited times. The platform is ad-supported so all tools stay free forever.
Is my PDF data safe when editing in the browser?
Completely safe. All editing — adding text, signatures, watermarks, redacting — happens inside your browser using JavaScript and PDF.js. Your files are never uploaded to any server at any point. Your documents never leave your device.
Can I add a handwritten signature to a PDF?
Yes. The Add Signature tool lets you draw your signature with a mouse or touchscreen, type your name in a handwriting font, or upload a photo of your real signature. Place it anywhere on the PDF page and adjust size.
Is PDF redaction truly permanent?
Yes. Our Redact PDF tool performs true redaction — it permanently destroys the underlying content beneath the black box, not just visually covers it. The text cannot be recovered by selecting, copying, or viewing the PDF source.
Can I fill in a PDF form that was sent to me?
Yes. The Fill PDF Form tool detects interactive form fields automatically and lets you type into them. For non-interactive PDFs (flat forms), use the Add Text to PDF tool to type directly over the form fields.
Can I compare two versions of a PDF document?
Yes. The Compare PDFs tool loads two PDFs and highlights every difference — added text, deleted text, moved images — in a color-coded overlay. You can export the differences as a marked-up PDF report.
What types of stamps can I add to a PDF?
The Add Stamp tool includes pre-built stamps: DRAFT, APPROVED, REJECTED, CONFIDENTIAL, PAID, VOID, FOR REVIEW, and COPY. Use the Custom Stamp Creator to design your own text or image stamp with custom colors, fonts, and borders.
Do watermarks I add stay visible in print?
Yes. Text and image watermarks added with our tools are embedded directly in the PDF page content and will appear in all prints, previews, and exports — exactly as shown in the preview.
