Split PDF by Page Range: Extract Exactly the Pages You Need

A long PDF rarely needs to travel whole. Usually it is one signed page, one chapter, or one invoice inside a monthly export, and sending the rest is noise. A page-range split copies only the pages you name into a fresh PDF, and the part that actually goes wrong is how the range field reads your numbers.

Use the free tool: Split PDF by page range - private, in-browser.

How the range field is read

The splitter treats the range box as a comma-separated list. Each entry is a single page (5) or a block (12-28), and the pages are copied into one new PDF in page order. Five behaviours explain most surprises:

• Duplicates collapse. 2, 2, 5 gives pages 2 and 5, not three pages.
• The output is always ascending. 5, 2, 9 becomes 2, 5, 9; the order you type is not the order you get.
• Descending ranges are flipped. 10-1 is read as 1-10, and 9-7 as 7-9.
• Overruns are clamped. On a 20-page file, 18-25 yields 18, 19, 20.
• Unparseable entries are skipped. p. 5, 1;3, 3 to 7, and 1–3 with an en dash are ignored rather than guessed at. A page number entirely past the end adds nothing; 999 on a 20-page file is simply dropped.

Because of the sort, output always looks like the original document with pages removed, never a shuffled packet: 5-7, 1-3 returns 1, 2, 3, 5, 6, 7, and 20, 19-16, 15-1 returns the full document in its original order. The split step cannot reorder pages; if sequencing matters, see the reorder option below.

If no entry parses — an empty box or only skipped tokens — the split stops with "Please enter valid page ranges" and the file is untouched.

Before you start

Check the page count. Once the PDF loads, the panel shows Total pages: N. Plan ranges against that number.

Translate printed page numbers. A report may print "Page 12" on what is physically the fifteenth PDF page once a cover, contents page, and blanks are counted. The tool counts physical pages from 1. Find a page with a known printed label, note the reader's counter for it, and apply that offset to every number you type.

Unlock protected files. An encrypted PDF cannot be parsed for splitting. Remove the password in a reader, save a copy, then split that.

Step by step

1. Open Split PDF. The split panel is embedded in the page, with nothing to install.
2. Add the PDF. Drag it onto the drop area or click to choose a file. It loads locally, and the page count appears underneath.
3. Type the ranges, for example 1-3, 5, 8-10.
4. Or use the shortcut buttons. All fills 1-N, Odd fills 1, 3, 5..., Even fills 2, 4, 6..., and First 10 writes 1-10 when the document has at least ten pages. Each button produces a plain list you can edit by hand.
5. Click Split PDF. The work happens on your device, so there is no upload progress bar.
6. Preview the output in the panel, or open it in a new tab for a full view.
7. Download split.pdf, or press "Clear result" to try a different range.

The range box remembers your last entry in the browser, so repeating a split after a reload does not mean retyping it. That stored value never leaves your device.

Range syntax at a glance

| Goal | Type | Output | | --- | --- | --- | | One page | 5 | 5 | | A block | 12-28 | 12 through 28 | | Scattered pages | 2, 6, 9 | 2, 6, 9 | | Mixed list | 1-3, 5, 8-10 | 1, 2, 3, 5, 8, 9, 10 | | Block typed backwards | 10-1 | 1 through 10 | | Overlapping list | 1-4, 3-6 | 1 through 6 | | Range past the end | 18-25 on 20 pages | 18, 19, 20 |

The grammar is narrow on purpose: digits, a plain hyphen between two numbers, commas between entries. Spaces around a hyphen (1 - 3) are fine; words, semicolons, "p." prefixes, extra hyphens, and typographic dashes are not, and those entries are dropped. If a result looks shorter than expected, compare it against this table before blaming the file.

Using the Odd and Even buttons

Alternating pages are common in scanned paperwork. A duplex scanner fed single-sided pages often produces front, back, front, back, with blank backs; Odd or Even isolates one side in a single pass. The same trick pulls every other page from a spread scan or a booklet. Both buttons write an explicit list, so a 7-page document becomes 1,3,5,7 or 2,4,6; delete entries afterwards if you want odd pages but not the cover.

When page order matters

Splitting sorts, so it cannot shuffle. If a signed page belongs at the front of a packet, extract the pages first, then run the result through Reorder PDF pages and list the final sequence there — that tool preserves the order you type and offers Fill 1…N and Reverse N…1 helpers. For the opposite job, deleting a section and keeping the rest, Remove PDF pages is faster than typing everything you want to keep.

Common jobs and the range to use

• Signature page from a contract: the physical page number, such as 14.
• One chapter from a manual: 37-58.
• Two halves of a report: split with 1-15, then run it again with 16-30; each run makes its own file.
• Front matter only: 1-4.
• Everything except the appendix: split 1-40 rather than building a long exclusion list, or use the remove tool.

After the split

• Emailing it? The extract is smaller than the original, but scanned pages stay heavy. Compress the PDF — the optimization is lossless structural work, so savings vary by file.
• Reassembling later? Merge the PDFs when the edits are done.
• Needing images? Convert the extract with PDF to JPG instead of screenshotting pages.
• Rename right away. The default download is split.pdf, and a folder of those is hard to untangle.

Keep the original until you have opened the output and confirmed the pages.

Troubleshooting

"Please enter valid page ranges." Nothing parsed. Look for semicolons instead of commas, words mixed into the field, an en dash, or a triple range like 1-3-5.

Fewer pages than you listed. Duplicates collapsed, entries were skipped, or part of a range fell outside the document. 1-4, 3-6 always collapses to a single pass.

A range past the end did not error. Ranges that start inside the document are clamped to the last page; a number entirely past the end is dropped.

Wrong pages came out. Check the printed-label versus PDF-page offset.

"Failed to split PDF." Usually an encrypted or damaged file. Unlock it in a reader, re-save, and retry.

A long document feels slow. Time scales with page count and image weight, all processed on your device. Split a section at a time.

Download or preview does nothing. Allow downloads for the site and run it again; if the inline preview is blank on a phone, use "Open in new tab."
