Split PDF by custom ranges, equal parts, or odd/even pages.
If this tool isn’t working as expected, please take a screenshot of the error and report the problem here so we can investigate and improve it.
PDF files often need to be broken apart for different audiences, submission requirements, or upload limits - a large report might need individual sections shared with different stakeholders, or a scanned document might need its odd and even pages separated. Because splitting only reorganizes existing pages rather than re-rendering them, the output pages are identical in quality to the source document.
This PDF splitter separates a PDF into multiple files by page range, equal parts, odd/even pages, or one file per page - entirely in your browser, using the client-side pdf-lib library. Your document is never uploaded to any server.
Upload the PDF you want to split.
Select page range, equal parts, odd/even pages, or all pages separately.
Click the split button to generate output files.
Download each split PDF individually.
Select Page Range, then enter a comma-separated list like "1-5, 8, 10-12" - each range or single page becomes its own separate output PDF.
Select Equal Parts and choose how many parts (at least 2) - the tool divides the total page count as evenly as possible across that many files.
Select Odd & Even Pages to get exactly two output files - one with all odd-numbered pages, one with all even-numbered pages - useful for cleaning up duplex scans.
Select All Pages Separately to generate one single-page PDF for every page in the original document.
Click the Download button next to each file in the results list - there's no bulk download, so for many output files you'll click Download once per file.
Best For
Input
Page Range mode, entry: "1-3, 7, 9-12"Output Files
pages_1-3.pdf (3 pages), pages_7-7.pdf (1 page), pages_9-12.pdf (4 pages)Each comma-separated entry becomes its own separate PDF file - a single page number like "7" produces a one-page file, not a page added into a combined file with the other entries.
Input
Odd & Even Pages mode, 10-page source documentOutput Files
odd_pages.pdf (pages 1, 3, 5, 7, 9), even_pages.pdf (pages 2, 4, 6, 8, 10)This mode always produces exactly two files regardless of the source page count.
Use Page Range mode with the exact page numbers of the section you need.
Use Odd & Even Pages mode to split a document scanned front-and-back into its two page sequences.
Use Page Range mode to create one file per section a portal or recipient requires separately.
Problem
Solution
Entering "3,7,10" produces three separate single-page PDF files - one for each entry - not one file containing pages 3, 7, and 10 together.
Problem
Solution
Each split result has its own Download button - there's no option to download all outputs as a single ZIP archive.
Problem
Solution
The tool can't open an encrypted PDF - remove the password first, or the upload will fail with an error.
Problem
Solution
The tool requires at least 2 parts and shows an error if you enter fewer.
You don't need to write "7-7" - entering just "7" in the range list produces the same single-page file.
The tool displays the total page count right after upload, which is useful for planning range or equal-parts input before splitting.
Since encrypted PDFs aren't supported, unlock a password-protected file in another tool first if you need to split it here.
If you're splitting into many files (e.g., all pages separately on a long document), expect to click Download once per file, since there's no ZIP option.
Split output files must be downloaded individually, one Download click per file - there's no bulk/ZIP download option.
The tool can't open encrypted PDFs - a password-protected file needs to be unlocked elsewhere before uploading it here.
Split output files contain only the copied page content - document-level metadata and bookmarks/outlines from the original aren't carried into the new files.
There's no artificial size limit built into the tool, but since everything runs in your browser tab, very large PDFs are limited by your device's available memory rather than a fixed cap.
A range where the start page is greater than the end page, or that falls entirely outside the document, is skipped rather than flagged individually - check your output file list against what you expected.
All four modes read the same uploaded PDF - only how the output files are divided differs.
| Page Range | Equal Parts / Odd & Even / All Pages Separately | |
|---|---|---|
| What you specify | Exact pages or ranges, e.g. "1-5, 8" | Just a number of parts (Equal Parts) - or nothing at all (Odd & Even, All Pages Separately) |
| Output file count | One file per range/page entry you type | Exactly your chosen number (Equal Parts), exactly 2 (Odd & Even), or one per page (All Pages Separately) |
| Best for | Pulling out specific known sections or pages | Dividing evenly, separating duplex scans, or fully exploding a document into single pages |
Which should you use?
Use Page Range when you know exactly which pages you need; use the other three modes when you want the tool to divide the document for you by count, parity, or into single pages.
The most common question is whether splitting affects the document's quality. It doesn't - splitting only reorganizes pages using the original page content, so there's no re-compression or re-rendering involved. The FAQ below also covers page-range syntax, the download format, and password-protected files.
Yes. This PDF Splitter processes your file entirely in your browser using the client-side pdf-lib library - your PDF is never uploaded to any server. You can verify this yourself by opening your browser's DevTools Network tab before splitting a file.
There's no artificial size limit imposed by the tool itself, and no watermark is added to the output. Since everything processes in your browser, practical capacity depends on your device's available memory - very large PDFs may be slow or fail to process in a memory-constrained browser tab.
Enter a comma-separated list in the input field - each entry can be a range like '1-5' or a single page like '7'. The tool creates one separate PDF file per entry, so '3,7,10' produces three separate single-page files (for pages 3, 7, and 10), not one combined file containing all three pages.
Yes. Select "All Pages Separately" from the Split Mode dropdown, and every page of your PDF will be saved as its own separate PDF file, ready to download individually.
No. PDF splitting only reorganizes pages - it does not re-compress or re-render any content. Text, images, and formatting in the split PDF pages are identical to the original document.
No. Each output file appears in a list with its own Download button, and you click each one individually - there's no bulk ZIP download. This works fine for a handful of files, but splitting into many individual pages means many separate clicks.
No. The tool needs to read the PDF's page structure to split it, and it doesn't support entering a password to unlock an encrypted file first. Remove the password from the PDF before uploading it here.
