How to Merge PDF Files Online
Combining reports, invoices, scans, or application documents should take minutes—not a software installation. This guide explains the simplest way to merge PDFs while keeping the pages in the right order.
Merge PDF filesMerge PDFs in three steps
PDF Tools merges files in your browser, so your documents stay on your device during the operation.
- 1.Open Merge PDF and add at least two files.
- 2.Arrange the files in the order you want them to appear.
- 3.Select Merge and download the combined PDF.
How to choose the correct file order
Name files clearly before uploading, such as 01-cover, 02-report, and 03-appendix. Review the displayed order before merging. If individual pages need rearranging afterward, use the Reorder Pages tool.
When to compress the finished PDF
Merging can create a large document when source files contain scans or high-resolution images. Compress the combined file after merging when you need to email it or meet an upload limit.
Frequently asked questions
Can I merge PDFs without uploading them?
Yes. The Merge PDF tool processes files locally in a supported browser.
Does merging reduce PDF quality?
Merging keeps the source pages as they are. Use compression separately only when a smaller file is needed.
