Merge PDF files online without uploading them to a server. This free browser tool combines multiple PDFs into one download in the order you choose. Processing uses pdf-lib locally in JavaScript — your documents never leave your device unless you save the merged file.

People search for merge pdf, combine pdf files free, and free tool to merge pdf files when invoices, scans, or chapter exports need to become one attachment. Privacy-conscious users also look for merge pdf without uploading; here there is no upload API and no server-side storage.

How to merge PDFs in your browser

Add two or more PDFs, drag to reorder, remove mistakes, then download a single merged PDF. No account is required.

Example: you scanned three signed pages as separate files and HR wants one PDF. Merge in order, download once. Another: a teacher receives weekly worksheets as separate exports — combine them for printing.

Privacy: files stay on your device

Merging runs entirely in your browser. We do not receive file names, page counts, or bytes. After this page loads, the tool does not send your PDFs over the network. If your organization forbids local PDF processing, follow your policy; for most personal use, local merge is the safer default.

Large files and errors

Very large PDFs need more RAM in the browser. If merging fails, close other tabs, try fewer files at once, or use a desktop browser. Password-protected PDFs must be unlocked first — this tool cannot guess passwords. If a file is corrupted, remove it and merge the rest.

Pair with split PDF

Need only part of a longer file first? Use our split PDF tool to extract pages, then merge the pieces here.

When PDF Tools Pro on iPhone is a better fit
