Merge PDF files

Combine several PDFs into one file, in the order you choose.

Select from device or drop PDF files here Processed on this device. Never uploaded.

    The short version

    Most online PDF tools upload your file to a server first. Client financials shouldn't sit on infrastructure you don't control — StayPutPDF works entirely in your browser: merge, redact and convert without a single number leaving your machine.

    Why the upload step is the problem

    A typical online tool

    Sends the file to a third-party server. A copy of your client's numbers now exists somewhere outside your firm.

    Why it matters to you

    Account numbers, tax IDs, payroll — explaining a free tool's data policy to a client is a conversation worth avoiding.

    What accountants do with StayPutPDF

    • Merge monthly invoices, bank and card statements, year-end client packets.
    • Redact account numbers, SSNs and tax IDs before sending a document on. It can find card, account and ID numbers automatically — automatic search can miss some, so check the result before you send it. How redaction works
    • Convert Excel to PDF — a clean, read-only copy of a budget or schedule. Excel guide
    • Sign engagement letters, edit and fill in forms.
    • OCR (Premium) — make scanned receipts and statements searchable.
    StayPutPDF Merge PDF with three files loaded in order, ready to merge
    Files are read locally the moment you drop them. Ordering and merging happen in the same browser tab.

    How to build a client packet

    1. Drop your PDFs into the box above — read straight from your device.

    2. Order them with ↑ ↓ the way the client should read them.

    3. Click "Merge PDFs" and download. No watermark, on any plan.

    How it keeps client numbers local

    The tools run with open-source libraries inside your browser tab. Your browser reads the file from your disk, does the work in memory and hands you back the result.

    There's no server call at any point — free or Premium — so no third party holds account numbers or tax IDs, even briefly. Check it yourself in a minute.
