Yes, 100%. Your PDF is processed entirely in your browser using JavaScript. It is never uploaded to any server. You can verify this yourself by opening your browser's Network tab (F12) before using the tool — you will see zero requests containing your document data.

This tool accepts PDF files. If you have a Word document (DOCX), you can convert it to PDF first using your word processor, then sign it here. For full format support including DOCX and images, create a free GoodSign account.

This tool places your signature image on a PDF — like printing and hand-signing, it depends on context. For signatures that are provably legally binding with full audit trails (timestamps, IP addresses, consent records), use GoodSign's full signing platform, which complies with ESIGN, UETA, and eIDAS.

Since everything runs in your browser, the practical limit depends on your device's memory. Most PDFs up to 50 MB work smoothly. Very large PDFs with hundreds of pages may be slower on mobile devices.

Yes. After creating your signature, navigate between pages using the Previous/Next buttons and click on each page to place your signature. You can place as many signatures as you need across any pages.

Absolutely. The tool is fully responsive and works on any device with a modern browser. Draw your signature with your finger on the touchscreen, then place it on the document.

No. This free tool requires no account, no registration, and no personal information. Just upload your PDF, sign it, and download. For advanced features like sending to others for signature, you can create a free account.

Nothing — it is gone. Since your PDF was never uploaded anywhere, closing the browser tab means the document only exists on your device where you originally had it (plus the signed copy you downloaded).
