Merge PDF
Drop your PDFs, drag them into the order you want, and get one clean document back.
About Merge PDF
Merge PDF joins several PDF files into a single document, in exactly the order you choose. Drop up to 20 files, drag them into place, and download one clean PDF.
It is the quickest way to turn a pile of separate files into one document you can send, print or archive: no software to install and no sign-up needed.
When to use Merge PDF
- Combine a cover letter, CV and certificates into one job application PDF.
- Put invoices or receipts from the same month into one file for your accountant.
- Join scanned pages that came out of the scanner as separate files.
- Assemble chapters or reports written by different people into one document.
Tips for the best result
- Check the order before you merge: drag the files until the list matches the document you want.
- Rename files with numbers (01, 02, 03) before uploading so they are already in sequence.
- If the result is too large to email, run it through Compress PDF afterwards.
