About PDF Splitter

The Zynocode Labs PDF Splitter is a client-side utility designed to extract pages or page ranges from PDF files. Many online tools require uploading documents, exposing sensitive contracts or financial details to third parties. Our splitter processes files 100% locally in your browser memory using pdf-lib. You can isolate specific chapters, extract individual receipts, or break down large files without uploading them to any external servers.

A PDF Splitter parses a document's internal catalog, cross-reference table, and page trees to isolate specific pages or page ranges. It then copies the selected page dictionaries into a brand-new PDF structure, generating separate, fully functional PDF files.

Definition: PDF Page Extraction

The process of extracting a subset of page objects from an existing PDF file structure (ISO 32000) and creating a new catalog entry to output one or more independent, valid PDF files.

Frequently Asked Questions

Are my PDF files safe with this splitter?

Yes, absolutely. Because the splitting is done using client-side JavaScript (pdf-lib) in your browser, your files are never transmitted to Zynocode or any other server.

What syntax is supported for page ranges?

You can specify individual pages separated by commas (e.g., '1, 3, 5') or ranges using hyphens (e.g., '2-6'). You can also combine them (e.g., '1, 3-5, 8').

Will the split PDF retain hyperlinks and text formatting?

Yes. Since the splitter copies existing page structures directly, the output files preserve all vector paths, text fonts, annotations, and hyperlinks.

What is the maximum file size limit for splitting?

We support files up to 20MB. Since all processing runs in the browser memory, performance depends on your device's RAM.

Can I split encrypted or secured PDF files?

No, if the PDF file is password-protected or encrypted, the browser engine cannot read it. You must decrypt it first before splitting.

Can I extract every single page as a separate file?

Yes, the tool allows you to extract all pages as individual files, which you can then download as a ZIP file or individual documents.
