How to merge PDF files

  1. Tap Choose PDF files (or drag them onto the box). Add two or more PDFs.
  2. Check the order. Use the up/down arrows or drag the handle to move a file. The page count of each file is shown.
  3. Remove any file you don’t need with the bin icon.
  4. Tap Merge PDFs.
  5. Tap Download merged PDF.

How it works

Every PDF is opened in your browser, and its pages are copied, in the order you set, into a brand-new PDF. Because pages are copied rather than re-drawn:

  • Text stays selectable and searchable.
  • Images keep their original quality.
  • Page sizes and orientation stay the same — you can merge A4 and Letter pages in one file.

Example

You need to send a single PDF for a job application containing your application form (2 pages), degree certificate (1 page) and experience letter (2 pages). Add the three files, put them in that order, merge — and you get one 5-page PDF ready to attach.

Common problems and fixes

  • “This PDF is protected” — the file has a password or editing restrictions. Open it, choose Print → Save as PDF to create an unprotected copy, and add that instead.
  • Pages in the wrong order inside one file — merge first, then fix the page order with organize PDF.
  • A page is sideways — use rotate PDF on the merged file.
  • The merged file is too big for a form — PDFs made from photos are often large. Convert the photos with JPG to PDF using “Make the PDF smaller”, then merge.

Getting documents ready before you merge

  • Collect everything first — scans, certificates and forms — and give them clear names, so they’re easy to put in order.
  • Convert photos to PDF with JPG to PDF; this tool only accepts PDF files.
  • Check page orientation after merging and fix any sideways pages with rotate PDF.
  • Mind upload limits. Many portals accept files of 1–5 MB. If the merged file is bigger, use smaller scans or the “make the PDF smaller” option when creating PDFs from photos.

Who merges PDFs

  • Job seekers and students combining certificates and forms into one upload.
  • Office staff putting together reports, invoices and annexures.
  • Home buyers and borrowers assembling KYC and loan documents.
  • Teachers combining question papers and notes.

Frequently asked questions

How do I merge PDF files on my phone?

Open this page in your phone’s browser, tap Choose PDF files and select your PDFs. Put them in order with the arrows or drag handle, then tap Merge PDFs and download the result. No app is needed.

Is it safe to merge confidential PDFs here?

Yes. The PDFs are combined inside your browser. They are never uploaded to a server, so bank statements, certificates and ID documents stay private.

Why can’t I merge a password-protected PDF?

A protected PDF is encrypted, and its pages can’t be copied into a new file without unlocking it. Open it with the password and use Print → Save as PDF to make an unprotected copy, then merge that.

Is there a limit on files or pages?

You can add up to 50 PDFs of up to 100 MB each. Very large documents may be slow on older phones because everything is processed on the device.

Will the merged PDF keep the quality of the originals?

Yes. Pages are copied as they are — text stays text and images are not re-compressed — so nothing is lost.

Do bookmarks and form fields survive merging?

The page content is kept exactly, but bookmarks (the outline) and fillable form fields from the original files may not carry over. Fill in forms before merging.

In what order are the files merged?

In the order shown in the list, from top to bottom. The first file’s pages come first. Rearrange the list with the arrows or the drag handle before you merge.
