PDF Split
PDF ToolsSplit PDF files by page ranges, specific pages, or every N pages to extract sections or divide large documents.. Free, private — all processing in your browser.
The PDF Split tool divides a PDF document into multiple smaller PDFs based on page ranges you specify. Useful for extracting chapters from a book, separating sections of a report, splitting a multi-page contract, or reducing file size by taking only the pages you need. The tool supports specific page ranges (pages 1-10), individual page extraction (page 5), every N pages split (split into 10-page chunks), and splitting by bookmarks (each chapter becomes its own PDF if bookmarks exist).
Upload the PDF, specify how to split, and download the result as individual PDFs or a ZIP archive. Preserves original quality — no re-encoding or degradation of text, images, or vector content. Works entirely in your browser using PDF parsing libraries so sensitive documents (contracts, internal reports, personal files) never leave your machine.
PDF Split — key features
Flexible page ranges
Specify ranges, individual pages, or combinations (1-5, 10, 15-20).
Split by count
Automatic splitting every N pages (e.g., every 10 pages).
Extract individual pages
Each page as its own PDF for page-level extraction.
Odd/even split
Separate odd-numbered and even-numbered pages into two PDFs.
Bookmark-based split
Split chapters based on PDF bookmark structure (if present).
Preserves quality
Pages copied without re-encoding — text, images, and vectors stay identical.
Form and annotation preservation
Fillable forms and annotations remain functional in split PDFs.
Client-side only
PDFs stay in your browser — safe for confidential documents.

Technical details
PDF splitting uses pdf-lib or similar JavaScript PDF libraries for lossless page extraction.
Process:
1. Parse input PDF into object model
2. For each desired range or individual page:
- Create new PDF document
- Copy specified pages (preserves all content: text, images, forms, annotations)
- Save as new PDF blob
3. Offer downloads individually or as ZIP
Page range syntax: standard comma-separated with hyphen ranges:
- 1-5 : pages 1 through 5
- 1,3,5 : pages 1, 3, 5 only
- 1-5,10,15-20 : combined ranges and individual pages
- -5 : pages 1 through 5 (shorthand)
- 10- : pages 10 through end
Split modes:
1. By ranges: extract specific ranges
2. By count: split every N pages (10-page chunks, 20-page chunks, etc.)
3. Odd/even: separate odd-numbered and even-numbered pages
4. By bookmarks: use PDF bookmark structure to split chapters (if bookmarks exist)
5. Individual pages: each page becomes its own PDF
Metadata preservation: document metadata (title, author, creation date) copied to each split. Some libraries copy all fields; others reset metadata per split.
Form fields and annotations: preserved in splits if the library supports it. pdf-lib handles forms, annotations, and interactive elements.
Security: encrypted PDFs need the password to open. If you provide the password, the tool can decrypt and split. Output PDFs are unencrypted by default; re-encrypt after if needed.
Size: each split file is proportional to its page count but may include the full font embeddings (which can\u2019t be easily split), so total split size often exceeds original.
Performance: PDF parsing and page copying is moderately computationally intensive. Multi-hundred-page PDFs take 5-30 seconds depending on content complexity.
Very large PDFs: scanning books with hundreds of pages may strain browser memory. For very large files, split in smaller batches or use desktop software.
Common problems and solutions
⚠File size not much smaller
Font embedding duplicated across splits. A 10-page split from a 100-page PDF isn’t necessarily 10% the size. Embedded fonts and shared resources bloat each split.
⚠Bookmark splits miss sections
If PDF bookmarks are incomplete or nested deeply, automatic chapter splitting may miss some sections. Review the output and adjust manually if needed.
⚠Very large PDFs slow
PDFs over 500 pages may be slow to process in browser. Use desktop tools for very large files.
⚠Encrypted PDF issues
Password-protected PDFs need the password. Without it, the tool cannot split. Decrypt first or provide password.
⚠Forms partially broken
Some form fields reference page indices that change when pages are extracted. Forms may not work correctly in splits. Test before relying on form functionality.
⚠Page numbers shift
If the PDF has printed page numbers in footers, those don’t renumber automatically. Page 10 in the split is still labeled \"10\" in the footer even if it’s now page 1 of the split PDF.
⚠Links broken
Internal links (to other pages in the PDF) may break if the target page isn’t in the split. External links still work.
PDF Split — comparisons and alternatives
Compared to Adobe Acrobat Split Document, this tool is free and browser-based. Acrobat offers more sophisticated split options and batch processing; this tool handles the common cases quickly.
Compared to pdftk or qpdf (command line), this tool has a browser UI. CLI is better for scripting and large batches; this tool for interactive work.
Compared to online splitters, this tool runs entirely in your browser without upload. Many online services upload PDFs to their servers; this tool keeps PDFs local.
Frequently asked questions about the PDF Split
▶How do I split a PDF into parts?
Upload your PDF, specify page ranges (e.g., 1-10, 11-20) or split every N pages, then download the resulting PDFs. Each part is a standalone PDF containing the pages you chose.
▶Can I extract a single page?
Yes. Use individual page mode or specify a single page number in the range (e.g., \"7\" extracts just page 7). The output is a single-page PDF.
▶Is quality preserved?
Yes. Pages are copied losslessly from the original. Text, images, and vector content maintain exact quality — no re-encoding or compression.
▶Can I split by chapter?
If the PDF has bookmarks for chapters, yes. Use bookmark-based split to automatically create one PDF per chapter. Without bookmarks, you need to specify page ranges manually.
▶How do I split a PDF in half?
Upload the PDF, see total page count, then specify the midpoint. For a 100-page PDF, split 1-50 and 51-100. Done in one operation with two ranges.
▶Does it work with password-protected PDFs?
You need the password. Provide it during upload and the tool can decrypt and split. Output PDFs are unencrypted by default; re-encrypt if needed.
▶Is my PDF private?
Yes. All splitting runs in your browser. PDFs never leave your machine — safe for contracts, personal files, and sensitive documents.
▶Can I split very large PDFs?
Yes, though performance depends on browser memory. PDFs under 500 pages split smoothly. Larger PDFs work but may be slow. For very large files, desktop tools like Adobe Acrobat or pdftk may be more efficient.
