About Merge PDF
Merging turns a pile of separate PDFs — invoices, scanned receipts, chapters of a report — into one file you can send, print or archive in a single go. avalpdf copies the original pages into a new document without re-rendering them, so text stays selectable and images keep their quality.
When people use it
- Sending one tidy attachment instead of ten loose files to an accountant or HR team.
- Combining a signed cover page with the rest of an application pack.
- Joining a scanned document that your scanner saved as one PDF per page.
Tips for better results
- Drag the file cards to set the order before you merge — the first card becomes page one.
- Password-protected files must be unlocked first; a locked PDF cannot be read for copying.
- If the merged file is too big to email, run it through Compress PDF afterwards.
