How to use this tool

  1. Add at least two PDFs and check their names.
  2. Use the arrows to arrange files in delivery order.
  3. Merge them and inspect each boundary between source documents.

An example you can verify

Combine a cover, report and appendices in delivery order. Each file contributes all of its pages.

Example input

sample-2-pages.pdf (B1, B2) + sample-3-pages.pdf (A1, A2, A3).

Expected result

One 5-page PDF: B1, B2, A1, A2, A3.

Check document boundaries and orientations. Use Interleave PDFs to alternate sheets from two scans.

Merge PDFs without uploading your files

Select documents and arrange files in delivery order. Complete blocks are combined; use Interleave PDFs for alternating fronts and backs. Download the copy and check document boundaries before sharing.

Continue your task

Download the result or copy the text before opening another tool. Then load or paste it into the next step; content is not transferred automatically.

Settings and limits

Add two or more files. Use the arrows to reorder them and select Merge PDF.

Between 2 and 30 PDFs, up to 120 MB per batch and 500 output pages. Encrypted PDFs are unsupported. Check links, forms, annotations and signatures after editing a document. Available memory may require smaller batches.
