Frequently Asked Questions

How do I sign a PDF document?
Upload your PDF, choose a signature method (draw, type, or upload), customize the appearance and position, then click 'Sign PDF'. Download your signed document when ready.
Which signature method should I use?
Draw is best for authentic handwritten signatures using mouse or touchscreen. Type creates clean, professional text signatures. Upload lets you use existing signature images from other sources.
Can I save my signature for future use?
Yes! After creating your signature, click 'Save Signature' and give it a name. Your saved signatures appear in the library for quick reuse in future documents.
Where are my saved signatures stored?
Saved signatures are stored locally in your browser's localStorage. They persist across sessions on the same device and browser, but are not synced across different devices. Clearing your browser data will remove saved signatures. For this reason, we recommend keeping a backup of important signatures.
Are my documents secure?
Yes. All signature processing happens in your browser - your PDF never leaves your device. We prioritize your privacy and document security.
Can I sign on mobile devices?
Absolutely! The draw signature method works great on touchscreens. You can draw your signature with your finger on phones and tablets. All three methods (draw, type, upload) work on any device.
Is this legally binding?
This tool creates visual signatures (similar to signing with a pen). For documents requiring digital certificates or advanced electronic signatures with legal verification, consult your legal requirements. Many contracts accept visual signatures.
What image formats can I upload?
You can upload PNG and JPEG/JPG image files. Make sure your signature image has a transparent or white background for best results.
Can I add multiple signatures to one document?
Currently, you can add one signature per processing session. To add multiple signatures, download the signed PDF, upload it again, and add the next signature.
