Frequently Asked Questions
Authoritative answers regarding format conversions, document quality, and portal standards:
Is signing a PDF with Kagazo legally valid?
Yes. Under the Indian Information Technology Act (2000) and equivalent electronic signature legislation globally (ESIGN Act, eIDAS), electronic signatures on commercial contracts, employment offers, and government application forms are legally binding.
Are my signed contracts uploaded to any cloud server?
Never. Kagazo processes your PDF and signature overlay 100% inside your browser memory (RAM) via client-side WebAssembly and PDF rendering libraries. Zero bytes leave your device.
Can I sign using my phone or tablet touchscreen?
Yes! Kagazo includes full touch and stylus support, allowing you to sign naturally with your finger or Apple Pencil / stylus on smartphones and tablets.
Does Kagazo inject any watermark or logo into the signed PDF?
No. Unlike commercial alternatives that demand expensive subscriptions or stamp promotional logos, Kagazo generates completely clean, unwatermarked documents.
Can I add multiple signatures or date stamps on different pages?
Yes. You can place multiple signature instances, initials, and date annotations across any page of a multi-page PDF before downloading.
Can I upload a photo of my physical paper signature?
Yes! You can take a photo of your handwritten signature on white paper, upload it, and our engine will remove the paper background to leave only pure transparent ink.
Which ink color should I use for government applications?
Official government portals (such as UPSC, SSC, and TNPSC) and banking authorities strictly recommend blue or black ink. Light colors or pencil scans should be avoided.
What is the maximum file size I can sign?
Because processing occurs in your local browser memory, you can sign large multi-page PDF documents up to 50 MB without encountering server upload limits.
Can I sign password-protected PDFs?
You should first unlock the PDF using Kagazo’s free "Unlock PDF" tool, then open it in the Sign PDF workspace.
Is an account or credit card required to sign documents?
