What Is PDF Splitting?
PDF splitting extracts specific pages from a multi-page document into separate files. This is useful when you need a single chapter from a large report, a specific page from a scanned package, or want to break a document into sections for different recipients. Convertilo splits PDFs using pdf-lib — each fragment retains the metadata, fonts, and quality of the original. All processing runs in your browser without uploading files to a server.
About PDF Splitting
Splitting a bulky PDF into focused sections speeds up reviews and approvals. The splitter lets you carve out chapters or single pages with precise control and zero quality loss.
How the splitter works
- Range-aware extraction that keeps bookmarks and internal links
- Chunk batching to export groups of pages in a single click
- Validation of page boundaries to avoid half-empty outputs
- Local processing to keep sensitive contracts on your device
Technology Behind Our PDF Tools
Our PDF tools are built on two powerful JavaScript libraries that run entirely in your browser:
pdf-lib — A library for creating and modifying PDF documents. Used for merging, splitting, and page manipulation operations.
PDF.js — Mozilla's PDF rendering engine for parsing and displaying PDF content. Powers our PDF viewer and page export features.
Canvas API — Browser's built-in rendering API used for converting PDF pages to image formats (JPG, PNG, WebP) at any resolution.
All operations are performed locally — your documents are never uploaded to any server, ensuring complete confidentiality.
Why our PDF splitter helps teams
Precision page ranges
Export individual pages or bundled chapters by typing the exact start and end numbers.
Instant packaging
Download every chunk as a single ZIP archive or grab only the sections you need.
Zero quality loss
The splitter copies original pages byte-for-byte so signatures, stamps, and scans remain crystal sharp.
PDF split FAQs
Can I export only part of a document?
Absolutely. Set the first and last page numbers and the splitter will only process that portion.
How do grouped exports work?
Use the Pages per file field to decide how many pages should go into each output PDF. For example, enter 5 to get five-page bundles.
Will comments and signatures stay intact?
Yes. We copy the original pages byte-for-byte, so annotations, stamps, and digital signatures remain untouched.
Do you store the PDFs I split?
No. Splitting is performed locally, ensuring confidential paperwork never leaves your device.
