Merge PDF

Combine several documents into one tidy file, in exactly the order you choose. It is the easiest way to send one attachment instead of five, or to keep a report and its appendices together.

How to use it

1. Select two or more files, in the order you want them joined.
2. Run the tool.
3. Download the combined result.

Order matters

The final document follows the order in which you select the files. Pick them as Report → Invoice → Terms and the report's sheets come first, then the invoice, then the terms — nothing is shuffled or sorted alphabetically.

When it helps

• Joining a cover letter, CV and certificates for a job application
• Sending one attachment instead of several for an invoice and its receipts
• Collecting chapters written by different people into one manuscript
• Archiving a project's paperwork as a single file

Merge vs extract

Merging joins whole files together. To pull just a few sheets out of one document, use Extract Pages.

Good to know

Password-protected or damaged files may need to be unlocked or repaired first. Many or very large uploads take a little longer to combine. Uploaded files are deleted from our server shortly after processing.

A worked example

A job applicant has a cover letter, a CV and three certificates as separate files. The employer's portal accepts only one upload. Selecting them in the order cover letter → CV → certificates produces a single, professional application file in seconds.

Tips for a tidy result

• Rename the files with numbers first (01-cover, 02-cv…) so selecting them in order is easy.
• Rotate any sideways scans before combining them.
• Remove blank or duplicate sheets beforehand to keep the result small.
• Protect the final file with a password if it contains personal data.

Common uses

• Monthly expense reports with receipts attached
• Tender or grant applications that require one submission
• Course packs combining lecture notes and readings
• Contracts with their annexes and signed pages

Troubleshooting

If one file will not join, it may be password-protected or damaged — unlock or repair it first. Very large combined files can exceed email limits; consider sharing a download link instead, or splitting the bundle into two parts.
