How to Merge and Split PDF Files Online (Free, No Upload)
Working with PDFs usually means one of two things: you have several files that should be one, or one big file you need to break apart. Both are quick to do — and you don't need to install anything or hand your documents to a server.
Why merge PDFs?
Merging is handy when you're assembling a report from separate exports, combining scanned pages, or bundling invoices for a single month. Instead of emailing five attachments, you send one tidy document.
Our Merge PDF tool runs entirely in your browser. Your files never leave your device, so it's safe for contracts, statements and anything confidential.
How to merge PDFs
- Open Merge PDF.
- Add two or more PDFs.
- Drag them into the order you want with the arrows.
- Click Merge and download the combined file.
Because pages are copied rather than re-rendered, text stays selectable and bookmarks are preserved.
Why split PDFs?
Splitting helps when a document is too large to email, when you only need a few pages, or when each page should become its own file (for example, splitting a batch of certificates).
How to split a PDF
- Open Split PDF.
- Choose Every page, Custom ranges (like
1-3, 8, 10-12), or Select pages visually. - Download the results individually or as a ZIP.
Do more with your pages
Once you're comfortable merging and splitting, try Organize PDF to reorder, rotate and delete pages in one place, or Delete PDF Pages to remove unwanted pages before sharing.
The bottom line: merging and splitting PDFs should be fast, free and private. With browser-based tools, it is.
