Two of the most common PDF tasks — merging several files into one and extracting pages from a PDF — are surprisingly easy to do for free in a browser, without installing any software.
When to Merge PDFs
Merging PDFs makes sense when you need to:
- Submit multiple documents as a single file (e.g., a job application with a CV, cover letter, and certificates)
- Combine monthly reports into an annual archive
- Assemble a multi-section document that was created in parts
- Attach several scanned documents to a single email
How to Merge PDFs in Your Browser
Go to PDF24x Merge, drag in all the PDFs you want to combine, drag them into the right order, and click Merge. The combined PDF downloads instantly.
A few things worth knowing:
- Page order matters. The merged PDF will follow the order of the files in your list. Take a moment to arrange them before clicking Merge.
- No page limit. You can merge PDFs of any length — a 1-page cover letter with a 50-page technical report, for example.
- Bookmarks and metadata. Simple merging doesn't preserve bookmarks from the original files. If you need to maintain a navigable table of contents, a more advanced tool is needed.
- File size. The merged file is roughly the sum of the originals. Compress it afterwards if you need a smaller file.
When to Split PDFs
Splitting is the reverse operation — taking one PDF and extracting some or all of its pages into separate files:
- Extract a single chapter from a large report
- Separate a combined bank statement PDF into individual months
- Pull out specific pages to share without revealing the rest of the document
- Break a large file into smaller pieces for easier email transmission
How to Split PDFs in Your Browser
Go to PDF24x Split, upload your PDF, and choose how to split it:
- Extract page range — enter something like "3-7" to extract pages 3 through 7 as a new PDF
- Split every page — creates one PDF per page, useful for separating a batch of scanned forms
- Split at specific pages — split the document at defined page numbers
Extracting a Single Page
To extract one page — say page 5 — enter "5-5" as the page range. This creates a new PDF containing only that single page. This is handy for pulling out a signature page, a specific invoice, or a certificate from a larger document.
Splitting a Scanned Multi-Page Document
Scanners often produce a single PDF from a stack of papers. If you scanned 20 separate forms into one 20-page PDF, you can use "split every page" to instantly create 20 individual PDFs. This is particularly useful for digitising stacks of documents that need to be filed separately.
Keeping the Original File Intact
Both merging and splitting are non-destructive — they create new PDF files and don't modify the originals. Your source files are untouched. This makes it safe to experiment with different page ranges or arrangements without worrying about losing anything.
Privacy Considerations
When you upload a PDF containing sensitive information to an online tool, consider where that file goes. Many services transmit your PDF to cloud servers for processing. Browser-based tools like PDF24x process everything locally in JavaScript — your files never leave your device, which is particularly important for financial or legal documents.
Alternatives on Desktop
If you'd rather use desktop software:
- macOS Preview — drag PDFs into the sidebar to reorder or merge pages. Completely free.
- Adobe Acrobat Pro — the gold standard, but expensive. Only worth it if you work with PDFs professionally every day.
- PDF24 desktop app — free desktop tool with the same capabilities as the browser-based version.
Summary
Merging and splitting PDFs requires no software, no subscriptions, and takes under a minute. Use a browser-based tool for privacy, understand that order matters when merging, and remember you can always extract a single page by entering a single-page range like "4-4".
