How to merge PDF files

  1. Add your files

    Select or drop the PDFs you want to combine. Photos (JPG, PNG) are welcome too.

  2. Put them in order

    Drag the files, or use the arrow buttons, so they appear in the order you need.

  3. Merge and download

    Press Merge PDF. Your combined PDF downloads straight away.

Everyday uses

  • Job and college applications – CV, cover letter, marksheets and certificates as one file for the portal.
  • Aadhaar front and back – scan each side separately, then merge them into a single PDF.
  • Expense claims – join invoices, bills and receipts so accounts gets one attachment.
  • GST and ITR paperwork – keep invoices, challans and statements for a month together.
  • Scanned pages – phone scans that arrived as separate files become one tidy document.
  • Assignments – cover page, answers and annexures submitted as one PDF.

Good to know

The merge tool copies every page exactly as it is — text stays selectable, links and image quality are not changed. Pages of different sizes (A4, Letter, landscape) can be combined in one file.

Need to merge only some pages? Merge first, then remove extras with Delete PDF pages, or pick pages first with Extract PDF pages. If the merged file is too large to email, run it through Compress PDF.

Private by design. Merge PDF works inside your browser. Your file is processed on your device and is not uploaded to our server.

Limits to know before you start

  • Bookmarks, a clickable table of contents and form fields from the original files may not carry over. Page content, text and images do.
  • You need at least two files. Photos can be mixed in, and each becomes a page sized to the photo.
  • Very large batches depend on your device’s memory. For hundreds of scanned pages, merge in two rounds.

If something goes wrong

The tool asks for a password. The PDF is protected. Type the password you normally use to open it; it is used only in your browser. The new file is not locked.

“Could not read this PDF”. The file is probably damaged or not really a PDF. Run it through Repair PDF, then try again with the repaired copy.

The files are in the wrong order. Drag them by the handle or use the arrows before you press Merge PDF. On phones the arrows are easiest.

The page becomes slow or reloads. Everything runs on your device, so very large files need a lot of memory. Close other tabs, or split the PDF and work on smaller parts.

Merge PDF – questions

How do I merge PDF files for free?

Open Merge PDF, add your files, drag them into order and press Merge PDF. It is free with no account and no watermark.

Can I merge PDF and JPG files together?

Yes. Add JPG, PNG or WEBP images alongside your PDFs. Each image becomes a page sized to fit the photo.

Is there a limit to how many PDFs I can merge?

There is no fixed limit. Because everything runs on your device, very large batches depend on your phone or computer’s memory — for hundreds of pages, merge in a few rounds.

Will merging reduce the quality?

No. Pages are copied without re-compressing, so text and images stay exactly as they were.

Can I merge password-protected PDFs?

Yes. You will be asked for the password of a locked file; it is used only in your browser to open the file.

Does it work on mobile?

Yes. It works in Chrome, Safari and other modern browsers on Android and iPhone. Use the arrow buttons to reorder on small screens.
