Frequently asked questions

Does merging reduce quality?
The tool copies PDF pages without intentionally recompressing their contents.

Combine several PDF files into one document directly in your browser. Alyvero is designed for ordinary document-merging tasks such as joining reports, receipts, forms or supporting documents before a submission.
When merging PDFs is useful
Merging is useful when a website accepts one document but your information is spread across several PDFs. It can also make a collection of related records easier to archive or share.
The tool creates a new combined PDF rather than changing the source files. Keep the originals until you have checked the result.
Check the file order
Alyvero combines files in the order selected. Before downloading the result, check that the pages appear in the intended sequence, especially when combining forms, receipts or supporting documents.
Before an important submission
Open the finished PDF and check page count, readability, orientation and any pages that contain signatures or forms. If the destination has a file-size limit, use Compress PDF after merging.
