How to Split a PDF (Extract Pages or Break Apart)

Splitting a PDF — pulling out specific pages, breaking a long document into smaller files — is the natural opposite of merging. You'd want to split when:

• A 200-page report has just 5 pages relevant to the email you're sending
• An invoice batch needs to be separated into individual invoices for filing
• A scanned document has chapters you want to share separately
• You only need to print pages 12-16 of a 100-page contract

Three split modes

Split PDF on Dropvert handles three different split strategies — each useful for different situations.

Mode 1 — Pick pages visually

Drop the PDF. The page renders thumbnails of every page. Click the pages you want to keep. They highlight. Click "Split PDF" and you get back a single PDF containing just the pages you picked.

This is the right mode when the pages you want aren't contiguous (page 1, then page 7, then pages 12-15). Just click them.

Mode 2 — Split every N pages

Useful for breaking a long batch into uniform chunks. A 100-page invoice batch where each invoice is 4 pages: set N=4 and you get 25 separate PDFs back, each containing one invoice.

This is also the simplest way to "extract every page as its own PDF" — set N=1.

Mode 3 — Custom ranges

Type a range expression like 1-3, 5, 8-10. Each comma-separated group becomes its own output file:

• 1-3 → first PDF with pages 1, 2, 3
• 5 → second PDF with just page 5
• 8-10 → third PDF with pages 8, 9, 10

The output is bundled into a zip file, with each output PDF named <original>-part-01.pdf, <original>-part-02.pdf, etc.

What each mode is good for

Situation	Mode
Extract specific pages (non-contiguous)	Pick pages
Break uniform batch into chunks	Every N pages
Custom split with multiple ranges	Custom ranges
Single contiguous range	Pick pages or use a custom range like 5-10

Common workflows

Extract just the relevant pages of a contract

A 50-page contract, you only need pages 12-16 for a follow-up email.

1. Drop in Split PDF.
2. Switch to Custom ranges.
3. Type 12-16.
4. Split.
5. Download — single PDF with those 5 pages.

Break a multi-invoice PDF into individual invoices

You exported a billing report that contains 30 invoices, each 3 pages.

1. Drop in Split PDF.
2. Switch to Every N pages, set N=3.
3. Split.
4. Download zip — 30 separate 3-page PDFs.

Pull out only the pages with charts

A 100-page annual report has charts on pages 14, 27, 41, 53, 68, 89.

1. Drop in Split PDF.
2. Use Pick pages, click each page with a chart.
3. Split.
4. Download — single PDF with all 6 chart pages.

Quality preservation

Splitting copies pages directly from the source PDF without re-rasterization. So:

• Text stays selectable in the output.
• Image quality is preserved — no compression artifacts added.
• Fonts are preserved — each output PDF includes the fonts used by its pages.
• Form fields on individual pages stay functional.

The output PDFs are roughly proportional in size to the number of pages — a 5-page split of a 50-page 5 MB PDF is roughly 500 KB, with the same per-page detail as the source.

Things that don't transfer

• Bookmarks (outline tree) for the whole document — each output is a fresh document.
• Document-level metadata (title, author) — gets the source's metadata; you may want to update it.
• Internal hyperlinks — links from page A to page B that survive the split only if both A and B are in the same output PDF.

Common questions

Can I rearrange pages while splitting? Not directly — the Pick pages mode keeps your selected pages in their original order in the output. To reorder, split first into individual pages (Every N pages with N=1), then drop them into Merge PDF in the order you want.

How big a PDF can Split handle? A few hundred pages is comfortable. The thumbnail render is the main bottleneck — for 500-page PDFs, expect 10-20 seconds before the page picker is ready.

What if my PDF is password-protected? Dropvert tries to load encrypted PDFs in permissive mode. If a password is required, you'll need to unlock the PDF with another tool first.

Are my files uploaded? No. The split runs entirely in your browser via pdf-lib (for split logic) and pdf.js (for thumbnails).
