No — that is the whole point when you’re handling property papers that carry your ownership and financial details. Your documents are opened, rendered with pdfjs, masked by flattening and merged with pdf-lib entirely on your device, with no server, no API and no CDN call for your files; the page even works offline once cached. Nothing is sent, logged or stored. That is exactly why you should never use a random online “merge documents” site for your title deed, EC and ID — those upload your most sensitive ownership & financial records to a stranger’s server. Here, only the merged PDF or ZIP you choose to export leaves the page, and closing the tab discards everything; your sensitive ownership & financial details stay on your device.

For buying and due diligence a typical set includes the registered title / sale deed proving ownership, the mother deed and an unbroken chain of title, the Encumbrance Certificate (EC) from the sub-registrar showing the property is free of loans, mortgages or court cases, the latest property tax receipts proving no dues, the Khata / mutation / property record showing the property in the owner’s name, the approved building or layout plan, the occupancy or completion certificate (OC / CC), applicable NOCs (society, bank, authority), the survey / measurement documents fixing the boundaries, RERA registration where the project requires it, and the buyer / seller photo ID & KYC. Registration at the sub-registrar adds the agreement to sell; a home loan adds the lender’s sanction letter, valuation and legal opinion; and selling means producing what a buyer’s lawyer asks for, including a loan-closure / no-dues certificate if a mortgage existed. The exact documents, verifications and registration rules vary by country, state, authority and property type (a flat, a plot, agricultural land and an under-construction unit all differ), so this tool gives you a checklist per scenario to organize against, but it is general guidance, not your jurisdiction’s official list and not legal advice.

Yes. A lawyer, bank or sub-registrar often prefers all your supporting documents in a single, ordered file for review. Upload your title / sale deed, EC, tax receipts, Khata, building plan, occupancy certificate, NOCs, survey documents and ID (images or PDFs), arrange them with the up/down arrows, set the property address and the owner / buyer name, and export one merged PDF that starts with an auto-generated cover/index page listing every document. If you instead need each file separately, export the ZIP, which contains each document flattened (masks baked in) on its own. Both are built entirely in your browser, so nothing is uploaded. Note that a merged pack is for organizing and review only — it does not verify title or replace your lawyer’s due diligence or the original registered documents.

No — the tool prepares and packages your documents only. It does not verify title or ownership, does not confirm a document is genuine, does not run searches, and does not register, file, value or approve anything; ticking a box or merging a file does not establish a clear title. Property documentation, registration and legal requirements are complex and vary by country, state, authority and property type, so you must confirm your own jurisdiction’s exact requirements and use official sources. Always have a qualified property lawyer verify the title, encumbrances and documents — the chain of title, the EC, approvals, any litigation and outstanding dues — before buying or transacting. Share only what you need to: the masking lets you cover details you don’t need to disclose (full ID / PAN / Aadhaar / account numbers, signatures), and because each box is burned into the page image and the PDF is rebuilt from those images, the hidden content is physically gone with no recoverable text layer — but you place the boxes, so review every page before exporting.
