This tool joins several PDF files into one, in whatever order you set. It is handy for the boring paperwork moments: a CNIC scan plus a utility bill plus a bank statement for a visa file, a set of chapter PDFs from a teacher, or a pile of invoices your accountant wants as a single attachment.

Everything happens inside your browser. Nothing goes to a server, which matters when the documents are tax returns or ID cards.

How to use

  1. Tap Choose PDF files or drop them here and pick two or more PDFs. You can add more later, they go to the bottom of the list.
  2. Check the list. Each file shows its page count and size once it has been read.
  3. Use the up and down arrows to set the order. On a computer you can also drag a file to a new spot. The top file comes first in the merged PDF.
  4. Remove anything you added by mistake with the X button.
  5. Change the Output file name if you want something clearer than "merged".
  6. Press Merge PDFs. The download starts on its own when it finishes. If your browser blocks it, use Download again.

What gets kept and what doesn't

The pages are copied exactly as they are: text stays selectable, images keep their original quality, and page sizes are not changed. A Letter page stays Letter next to an A4 page, so printed margins may differ a little between documents.

Some things live at the document level rather than on a page, and those don't always survive a merge. Bookmarks (the outline panel in a PDF reader), filled form fields and digital signatures are the usual ones. A signed PDF will open fine after merging, but the signature itself is no longer valid, because the file it was attached to has changed. If someone needs to verify a signature, send them the original file separately.

Locked and damaged PDFs

Bank statements and some government forms come with a password or with copy protection. If a file is locked, the tool tells you and leaves it out of the merge, because copying pages from an encrypted PDF without the password produces blank or garbled pages. The fix: open the file in a PDF reader with the password, use Print, and choose "Save as PDF". Merge that new copy instead.

If a file shows "Could not read this file", it is either damaged or not really a PDF (some apps save images with a .pdf name). Try opening it in your normal PDF reader first. If it opens there, print it to a new PDF and try again.

Tips for a tidy result

Put the most important document first, since many people only look at page one. If you are emailing the result, watch the total size shown under the list. Many email services cap attachments somewhere around 20 to 25 MB, so check the current limit for yours, and compress big scans before merging.

On a phone, merge a big job (say 30 files) in two or three batches. Phones have less memory, and a huge merge can make the tab reload.

FAQ

Is it free, and are my files uploaded anywhere?

It is free with no sign up. Your PDFs never leave your device; the merging runs in your browser, and you can even turn off your internet after the page loads.

Is there a limit on the number of files or pages?

No fixed limit. Your device's memory is the real limit: a laptop handles hundreds of pages, an older phone may struggle with very large scans.

Can I merge PDFs on my phone?

Yes, in Chrome, Safari or any modern mobile browser. Reorder with the arrow buttons.

Why is one of my files marked as locked?

That PDF is encrypted with a password or permissions. Open it with the password in a PDF reader, print it to a new PDF, and add that copy instead.

Will the merged PDF lose quality?

No. Pages are copied as they are, without re-compressing images or turning text into pictures.
