How to Merge Multiple PDFs into One Single File

Ever ended up with a bunch of separate PDF files that really should be together? Like scanned pages of a contract, monthly invoices, different chapters of study notes, or slides from a presentation. Sending them one by one is a pain, and it just looks unprofessional.

I deal with this constantly. That’s why I made the Merge PDF tool on PDF Linx. Now whenever I have multiple PDFs, I just drop them all in, rearrange if needed, and get one neat, organized file in seconds. Order stays exactly how I want, quality doesn’t drop — done.

Super Straightforward Steps (I use this all the time):

  1. Head to the Merge PDF tool
  2. Drag in all your PDF files (or click to select multiple)
  3. Reorder them by dragging the thumbnails if you want
  4. Click Merge and download your single combined PDF

No file size limits, no signup, no watermarks. Works perfectly for reports, contracts, eBooks, or just cleaning up your downloads folder.

My favorite follow-up: Once merged, if the file gets a bit big (especially with scanned pages), I run it through the Compress PDF tool. Shrinks it down nicely without losing quality — makes emailing or uploading way easier.

Got several PDFs lying around? Combine them now — takes less than a minute.
