Merge PDF files online
Combine two or more PDFs into a single file, in the order you choose. Merging happens in your browser, so your documents are never uploaded.
Everything runs on your device. Nothing you add or type is sent to any server.
How to use it
- 01
Drop your PDF files into the box above, or click it to choose files from your phone or computer.
- 02
Use the ↑ and ↓ buttons to put the files in the order you want. File 1 comes first in the merged PDF.
- 03
Press Merge. The combined file downloads as merged.pdf.
When merging PDFs helps
Many forms ask for a single file. A job application may want your resume, certificates and ID proof in one PDF. A loan or visa application often asks for bank statements from several months as one document. An invoice and its supporting bills are easier to email as one attachment than as five.
Merging also keeps related pages together. Scanned pages from a phone scanning app, chapters of a report exported separately, or signed pages returned one at a time can all become one tidy file.
Your files stay private
Many online PDF tools upload your documents to their servers. This one does not. The merging code runs inside your browser using your device's memory, so bank statements, ID cards and contracts never travel over the internet.
Tips for a good result
Pages keep their original size and orientation. If one file has a sideways page, fix it first with the Rotate PDF tool. If the merged file is too large for an email or upload portal, run it through Compress PDF afterwards. Password-protected PDFs cannot be merged; remove the protection first with Unlock PDF. Bookmarks are not carried into the merged file and fillable form fields may stop being fillable, so fill in forms first.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
There is no fixed limit on the number of files. Each file can be up to 200 MB. Very large jobs depend on your device's memory, so merging many big files can be slow on an older phone.
Will merging reduce the quality of my PDF?
No. Pages are copied exactly as they are, so text stays sharp, searchable text stays searchable, and images keep their original quality.
Does it work on mobile?
Yes. It runs in the browser on phones and computers, so no app is needed. Use an up-to-date browser such as Chrome, Safari, Firefox or Edge.
Why does it say my file could not be read?
The file may be damaged, not really a PDF, or protected with a password. Open it in a PDF reader to check, remove the password with Unlock PDF if there is one, and try again.
