Merge PDF

Put invoices, contracts, scanned pages or chapters together into a single PDF that is easy to send, print and archive. Upload up to 20 files, arrange them in the right order and merge them in seconds.

Merging is lossless: pages are copied exactly as they are, with their text, images, links and quality unchanged.

How to merge PDF files

1. Click Choose files or drag your PDF files into the box. You can add more files at any time.
2. Use the arrows to put the files in the order you want.
3. Click Convert and download the merged PDF.

Why use this PDF merger

• Combine up to 20 PDF files at once.
• Change the order before merging with simple up and down arrows.
• Lossless: pages, fonts and images are copied without re-compressing.
• Clear warning if a file is password-protected.

Tips for merging PDFs

Name your files in order before uploading (for example 01-cover.pdf, 02-report.pdf) so they appear in the right sequence. If one of the files is password-protected, unlock it first with our Unlock PDF tool. To make the merged file smaller for email, run it through Compress PDF afterwards.
