Merge & Split PDF

Two of the most common PDF chores — stapling several files into one, and pulling a handful of pages out of a big document — usually send people to a website that wants them to upload confidential contracts or scans to a stranger's server. This tool does both entirely in your browser. Your files are read locally, their pages are copied into a new PDF, and nothing is ever uploaded or its contents inspected.

Merge: combine files into one

1. Choose Merge.
2. Add two or more PDFs. They're combined in the exact order they appear in the list.
3. Merge & download a single combined PDF (saved as merged.pdf).

The order is set by the order you add the files, so add them in the sequence you want them stapled — cover letter first, then the report, then appendices. To change the order, clear the list and re-add them in the right sequence. Because pages are copied intact rather than re-rendered, text stays selectable, links keep working, and quality is untouched.

Extract: pull out specific pages

1. Choose Extract pages.
2. Add one PDF.
3. Enter a page range like 1-3,5.
4. Extract & download a new PDF containing just those pages.

How the range syntax works

The range box is more forgiving than it looks:

• Hyphens select a run: 2-6 grabs pages 2 through 6.
• Commas pick individual pages or join several ranges: 1-3,5,9-10.
• Pages are 1-based — the first page is 1, not 0.
• Out-of-range numbers are ignored. Ask for 1-100 on a 12-page file and you simply get pages 1–12; nothing errors.
• Reversed ranges are auto-corrected — 5-3 is read as 3-5.
• Malformed bits are skipped, so a stray character won't fail the whole operation.

The one gotcha: output is always in order

Pages come out sorted ascending and de-duplicated, regardless of how you typed them. Enter 5,1,1,3 and you get pages 1, 3, 5 — the tool won't reorder pages for you or repeat a page. So this is the right tool for selecting pages, but not for rearranging them into a new sequence. If you need a different page order, extract the pieces you want and then merge them back together in the order you'd like.

Practical notes

• Splitting a document is just extraction run twice: pull 1-10 for part one, then 11-20 for part two.
• Deleting pages works the same way in reverse — to drop page 4 of a 10-page file, extract 1-3,5-10.
• Scanned PDFs are handled fine; the tool copies whatever the pages contain, image or text, without altering it.

Everything runs locally against the PDF's own structure using an in-browser PDF library, which is also why there's no server-imposed file-size limit — the practical ceiling is your device's memory. Nothing about your documents is transmitted or logged.
