About Merge PDF

Merge PDF joins two or more PDF files into a single document, in the order you set. Add your files, use the arrows until the order is right, give the output a name and download it. Everything runs inside your browser with JavaScript, so your documents are never uploaded to a server and are dropped from memory as soon as you close the tab.

How to use Merge PDF

  1. Drop two or more PDF files into the box, or click to browse for them.
  2. Use the arrows in the file list to put the files in the order you want them merged.
  3. Type an output file name, such as tender-bid.pdf, in the options panel.
  4. Click Merge PDFs and download the combined file.

What people use it for

  • Combining twelve monthly bank statement PDFs into one file for a home loan application.
  • Putting an Aadhaar photocopy, PAN card and address proof into a single KYC attachment.
  • Assembling a tender submission where the portal accepts only one PDF upload.
  • Joining chapter-wise study notes that were downloaded separately into one printable file.

Good to know

Page size, orientation and rotation of each source file are preserved, so mixing A4 and legal pages is fine. Bookmarks, form fields and digital signatures are not carried over to the merged file. Password-protected PDFs must be unlocked first. Very large files depend on your device's memory, so merge in batches on an older phone.

Frequently asked questions

Is Merge PDF free and is there a file limit?
Yes, it is free with no sign-up and no watermark. There is no fixed limit on the number of files; the practical ceiling is your device's memory, and a few hundred pages merge comfortably on most phones and laptops.
Are my documents uploaded anywhere?
No. The merging happens in your browser, so bank statements and ID proofs never leave your device. Nothing is stored on our servers and the files are cleared when you close the tab.
Can I change the page order after adding files?
Yes. Use the arrows next to each file in the list before clicking Merge PDFs. Files are combined from top to bottom, and all pages of one PDF stay together as a block.
Will my digital signature survive the merge?
No. Merging rewrites the document, so a DSC signature on a GST or MCA filing becomes invalid. Merge the pages first, then get the combined PDF signed.
