- Compiling a project report: Multiple chapters or sections saved as separate PDFs merged into one final deliverable.
- Grouping invoices or receipts: Bundle invoices or expense receipts into a single PDF for accounting or submission.
- Job applications: Combine resume, cover letter, and certificates into one professional PDF submission.
- Legal and contract documents: Agreements, annexures, and exhibits are easier to manage as one combined document.
- Academic submissions: Join assignment sections, appendices, and reference lists into one submission-ready PDF.

How to Merge Scanned PDFs Into One File
PDF Linx merges any type of PDF — including scanned documents, image-based PDFs, and regular text PDFs — all in the same merge. You can combine a scanned invoice with a typed contract, or join scanned pages from different sources into one organized document.
If your scanned PDFs need to be made editable first, use the PDF to Word converter with OCR enabled — then merge the converted files after editing.
Does Merging PDFs Affect Quality?
No. PDF Linx merges files by joining the original page data directly — no re-rendering, no re-compression, no quality loss. Text stays sharp, images stay clear, and formatting remains exactly as it was in the original documents.
How to Control Page Order When Merging
Files are merged in the order you upload them. The first file uploaded becomes the first section of the merged PDF. To change the order, remove files using the X button and re-upload them in the correct sequence.
If you need to extract specific pages before merging, use the Split PDF tool first to isolate exactly the pages you need.
What to Do After Merging
File too large to email? Run the merged PDF through the Compress PDF tool to reduce size without losing readability.
Need to protect the merged file? Add a password using the Protect PDF tool before sharing sensitive documents.
Need to split pages later? Use the Split PDF tool to extract specific pages from the merged document.
Need to convert Word files before merging? Convert them to PDF first using the Word to PDF converter, then merge all PDFs together.
Works With Any Type of PDF
The Merge PDF tool works with all standard PDF files — created from Word, Excel, PowerPoint, scanned documents, image exports, or downloaded from the web. As long as the files are valid PDFs, you can combine them without issues.
