Merge PDF Files Online — Free, Fast & Private
PDFdukan's Merge PDF tool combines two or more unlocked PDFs into one file. Choose pages from each source and arrange the file cards before export; selected pages remain in their original order within each source PDF. The merge operation runs in the browser, while the page can still request ordinary site assets, analytics and third-party libraries.
Whether you need to combine a cover letter with your CV, merge monthly bank statements into one document, or assemble scanned pages into a single report, this free online PDF merger handles it without any software installation, account registration, or file upload to a cloud server.
Why Use PDFdukan to Merge PDFs?
Selected files are read by the browser-based merge code. Assess your browser and network before handling highly sensitive documents.
Select specific pages from each PDF, not just entire documents. Leave out cover pages, blank pages, or pages you don't need.
Drag and drop files into the exact order you want before merging. No need to rename files or re-upload in sequence.
The current tool does not require an account or add a PDFdukan watermark. Large or complex files can exceed a device's available memory.
How to Merge PDFs in 4 Simple Steps
- Add your PDF files — Choose two or more unlocked PDFs. Capacity depends on total size, PDF complexity, browser and available memory.
- Arrange the order — Drag the file cards or use the ↑/↓ buttons. This controls which source document comes first.
- Select pages (optional) — Click page numbers, use All/None, or enter a validated range. Pages from each source keep their source order.
- Merge and verify — Click Merge PDFs, download the result, then open it and check page order, links, forms and fonts before submitting it.
Common Use Cases for Merging PDFs
- Job applications: Combine your CV, cover letter, degree certificate, and experience letters into one clean PDF before submitting to a portal.
- University admissions: HEC, universities, and scholarship portals often require a single PDF containing all documents.
- Bank and legal documents: Merge multiple bank statements into one file for a loan application or visa process.
- Scanned documents: If you scanned a multi-page document page by page, merge the individual PDFs into one complete file.
- Invoices and receipts: Freelancers and small businesses can merge monthly invoices into one PDF for accounting or tax purposes.
Frequently Asked Questions
The interface does not set a fixed file-count limit, but the practical limit depends on total file size, PDF complexity, browser and available device memory. Add fewer or smaller files if processing fails.
The selected PDF data is processed by client-side PDF code in your browser. The page can still request normal site assets, analytics and third-party libraries, so assess your browser and network before handling highly sensitive material.
The tool copies selected pages with PDF-lib instead of deliberately rasterising them, so image resolution is not intentionally reduced. Complex forms, signatures, annotations, links or unusual fonts may behave differently after rewriting; verify the output before relying on it.
Yes. First convert your images to PDF using the JPG to PDF tool, then merge the resulting PDFs together. Both tools are free and work in your browser.
Yes. After uploading, click on any file card to open the page selector. You can deselect individual pages — for example, remove blank pages, duplicate covers, or confidential sections before merging.
The current merge code does not intentionally add a visible PDFdukan watermark. Always open the output and check it before sharing or submitting.
There is no fixed limit enforced in the form. Available memory, file complexity and browser limits determine what can be processed. Very large files may be slow or fail, particularly on phones.
It depends on your device memory and the structure of the source PDFs. Password-protected, damaged or unusually complex PDFs may fail, and interactive elements should be checked in the result. Keep originals until the merged file has been verified.
