How to Merge, Split and Reorder PDFs Without Installing Software

Merging a stack of scanned pages, splitting a huge report into chapters, or fixing a page that's upside-down are some of the most common PDF tasks — and among the easiest to do entirely in your browser, without installing desktop software or creating an account on an upload-based converter site.

Merging PDFs the right way

When merging multiple files, order matters more than most people expect — most tools merge in the order you add the files, so it helps to name your files with a numeric prefix (01-, 02-, 03-) beforehand, or drag them into the correct order before merging, rather than fixing page order afterward.

Splitting: by page range or by size

There are generally two reasons to split a PDF: to pull out a specific section (like extracting one chapter from a textbook), or to break an oversized file into smaller pieces that fit an upload or email limit. Most PDF tools support extracting by page range (e.g., pages 5 through 12), which is the more common and more precise option if you know exactly what you need.

Rotating pages without redoing your scan

Sideways or upside-down pages are a frequent side effect of scanning multi-page documents on a flatbed scanner or with a phone camera app. Rather than rescanning, most PDF tools let you rotate individual pages (or the whole document) in 90-degree increments and save the corrected version — a two-minute fix instead of a re-scan.

Reordering pages

If a scanned document came out of order — a common issue with automatic document feeders — reordering lets you drag pages into the correct sequence without touching the original scan quality.

01

Merge

Combine multiple PDFs (or images) into a single file, in your chosen order.

02

Split

Extract a page range, or break a large file into smaller chunks.

03

Rotate & reorder

Fix sideways pages and drag pages into the right sequence.

Why do this in the browser instead of desktop software?

Browser-based PDF tools skip the install, the license, and — when they process files locally rather than through an upload — the wait for a file to travel to a server and back. For one-off tasks like fixing a single rotated page or merging three scans before an email, that's usually faster than opening a full desktop PDF editor.

Working with a password-protected or highly sensitive PDF? Check whether a tool processes files locally in your browser (rather than uploading them to a server) before using it — our Privacy Policy explains how Pixformet handles this.

Our Merge, Split & Rotate PDF tool covers all three of these jobs in one place, processing everything locally in your browser.
