When merging PDFs helps

Merge PDFs when you have several related documents—contracts, appendices, scanned IDs, or report chapters—and you want one file to send or upload. Ordering pages before you merge saves time later.

Combine cover letter + resume into one PDF
Join scanned chapters for reading or printing
Assemble forms that arrived as separate files

Before you merge

Check that every file opens correctly and that page order matches how you want the final document to read. After merging, download and open the result once to confirm the sequence.

We process the PDFs, return the merged file, and do not keep your uploads.

Do I need to install software for Merge PDFs?▾

No. We process your file to complete the request, return the result for download, and do not keep your uploads. We do not sell your files or publish them for others to browse.

Is there a file size limit for Merge PDFs?▾

Very large files may take longer or fail depending on your device and connection. For best results, start with a typical document or image size and split oversized batches if needed.

How many PDFs can I merge?▾

You can merge two or more PDF files. Reorder them before merging so pages appear in the order you want.

Will bookmarks or forms be preserved?▾

Merging copies page content into one file. Complex interactive features may not always carry over the same way as in desktop PDF editors.
