Frequently Asked Questions

There is no hard limit on the number of files. In practice you are bounded by your own patience and the 50 MB per file allowance, so dozens of documents merge in one go.
No. The pages are copied across as-is rather than rendered and re-compressed, so text stays selectable, images stay sharp and hyperlinks keep working.
Yes, the file list is fully editable before you merge. Drag items to reorder them and the resulting PDF follows exactly that sequence.
No. Your files live only in temporary storage for the length of the job and are wiped as soon as the merged download is ready.

About PDF Merger

The PDF Merger takes a stack of separate documents and stitches them into a single file in the exact order you choose. Contracts, bank statements, invoices and application forms that arrive as individual attachments are the classic case, as is anyone trying to email a folder of scanned pages and running into attachment limits.

Because order matters so much in a combined document, the file list is fully editable before anything is generated. You can drag a document to a new position, delete the one you added by accident, and see the running page count update as you go. That preview step saves a lot of pain compared with merging first and redoing it afterwards.

There is no limit on the number of files you combine, and each one can be up to 50 MB, so long reference packs and annual records are practical. The finished document is an ordinary PDF with no added pages, watermarks or restrictions, ready to email, upload to a portal or print.

When to Use This Tool

  • Attaching a contract and its addenda as one file instead of several
  • Compiling monthly bank statements for an accountant or auditor
  • Submitting a complete application packet when a portal allows one PDF only
  • Collecting signed pages from several people into a single agreed document
