How to merge PDF files online
Merging takes a few PDFs and joins them into one file. The pages keep their size, text and pictures. Nothing on them is redrawn.
- Add two or more PDFs. You can drag them onto the page or pick them from your phone or computer.
- Each file shows its name, size and number of pages, so you can check you added the right ones.
- Use the up and down arrows to set the order. The file at the top comes first in the result.
- Press Merge PDFs and download the combined file, called merged.pdf.
You can add up to 30 PDFs in one go. If you have more, merge them in two batches and then merge the two results.
Changed your mind about a file? Press the small cross next to it to take it out of the list. Nothing happens to the file on your device. The merge only starts when you press the button, so you can add, remove and reorder as much as you like first.
The result keeps every page of every file, from the first page of the first PDF to the last page of the last one. Page sizes are not forced to match, so an A4 letter and a legal-size form can sit in the same file. Each page looks just as it did before.
When people combine PDFs into one
Many online forms accept only one upload. So you need to join PDF files before you apply. Some common cases:
- A job application that wants your CV, degree and experience letters as a single PDF.
- NTS, PPSC or FPSC forms where the matric, intermediate and degree certificates must go in one file.
- University admission portals that ask for transcripts, CNIC and domicile together.
- Bank account opening or visa files with salary slips, bank statements and a cover letter.
- Students joining assignment parts written by different group members.
In the office it also helps to combine monthly invoices or reports into one file before you email it. One attachment is easier to open than ten.
A good habit for applications is to follow the order of the checklist. If the form lists CNIC, then matric, then degree, put the files in that order. The person checking your file finds each document where they expect it.
Merge PDF and JPG, or scanned pages, into one PDF
This tool joins PDF files only. If some of your pages are photos, first turn them into a PDF with JPG to PDF. Then add that new PDF here with your other files.
The same trick works when you scanned a document one page at a time on your phone. Make one PDF from the photos, or merge the separate scanned PDFs here in the right order.
Tips if merging does not work
- A file marked Password-protected can't be merged. Remove the password with Unlock PDF first (you need to know it).
- A file marked Can't be read is probably damaged or not a real PDF. Try saving or downloading it again.
- If the combined file is too big for a form, run it through Compress PDF afterwards.
- Need page numbers across the whole file? Merge first, then use Add page numbers on the result.
Check the order once more before you press the button. It is quicker than splitting the file and merging it again.
Is it safe to merge PDFs here?
Your PDFs are joined inside your own browser, so they are not uploaded anywhere. That matters for CNIC copies, bank papers and result cards. It also means merging is fast, even on a slow internet connection, and it works the same on Android, iPhone and a laptop.
