How to Merge and Split PDF Files for Free

Merging PDFs means combining several documents into one file; splitting means pulling pages or chapters out of a file into new ones. Both are routine office tasks — expense reports, contracts, scanned chapters — and neither requires installing software: modern browsers can rearrange PDF pages locally with surprising speed.

1. Merge: combine first, sort later

Drop the files in reading order. If a document lands in the wrong position, drag its pages into place before exporting — fixing order after the merge means doing the whole job twice. Use our PDF page manager to merge, then split, rotate or delete pages in the same session.

2. Split without losing quality

Splitting a PDF never touches the page content itself: text stays selectable and images keep their resolution, because only the page tree is rewritten. Extract a page range for sharing, or delete blank and duplicate pages to shrink a file before sending it.

3. Keep it local

PDFs often contain contracts, IDs and financial data. A tool that processes files entirely in your browser never uploads anything, so sensitive pages never leave your device — prefer it over upload-and-email-back services whenever the document matters.
