What is PDF Merge?

PDF Merge (also called PDF combine or PDF join) is the process of taking two or more separate PDF documents and combining them into a single, unified file. Whether you have a multi-chapter report saved as individual files, a set of scanned invoices, or presentation slides spread across several PDFs, merging them into one document makes sharing, archiving, and printing far more convenient.

When should you merge PDFs?

There are many everyday situations where combining PDFs saves significant time:

Business reports: Assemble monthly data exports, cover pages, and appendices into one polished document before sending to stakeholders.

Scanned documents: Scanners often produce one PDF per page. Merge them back into a complete, single file.

Academic submissions: Combine your thesis chapters, bibliography, and annexes into the single file required by most institutions.

Contract packages: Bundle a main agreement with its schedules and exhibits so the recipient receives everything at once.

Portfolio creation: Designers and photographers often merge individual project PDFs into one showcase document.

How to merge PDFs with TimeSave

TimeSave PDF Merge runs entirely inside your browser — your files are never uploaded to any server. Here is the step-by-step process:

Click Choose Files or drag and drop your PDF files into the upload area.

Review the file list. Drag the handle on the left of each row to reorder files into the sequence you want.

Click Merge & Download. The browser combines the files locally and saves the result to your computer.

Tips for best results

Check page orientation before merging. If some files are portrait and others landscape, the merged PDF will preserve both orientations — use the Rotate tool first if you want everything consistent.

Very large files (over 200 MB total) may slow down processing. For best performance, keep the total size under 100 MB.

The output filename is automatically generated from your first file's name. Rename it in your file manager after downloading if needed.

Frequently asked questions

Is there a limit on the number of files I can merge?

There is no hard limit on the number of files. You can add as many PDFs as you like. The practical constraint is your device's available memory — very large collections of high-resolution files may cause the browser to slow down.

Will the merge preserve hyperlinks, bookmarks, and form fields?

Yes. TimeSave uses the pdf-lib library, which faithfully copies page content including embedded links, annotations, and most interactive form fields from each source document into the merged output.

Can I merge password-protected PDFs?

Password-protected PDFs cannot be merged until they are unlocked. Open the file in your PDF viewer, remove or enter the password, then save an unprotected copy before using the merge tool.
