Local split workflow: page previews, range planning, chunking, and output packaging run in this browser session.
How to use Split PDF
A clear browser-session workflow for split PDF work.
The interface should make the route visible: select files, perform the operation, and download the output from the same session.
02
Choose pages or ranges
Select specific pages or define ranges for extraction. The engine maps the document structure locally.
03
Download split files
Selected pages are extracted in the browser and prepared for local download without a server round-trip.
Why local processing matters
Compare the processing route before using sensitive documents.
DocuStitch labels supported workflows around the browser session rather than hiding the path behind a generic cloud promise.
DocuStitch supported workflow
- Files selected on device
- Operation runs in browser session
- Output downloads from the tab
Typical cloud workflow
- Files uploaded to remote queue
- Processing depends on server retention policy
- Output returned after transfer
How it works
Extraction should make page boundaries and output intent explicit.
Page boundary detectionThe engine identifies exact page boundaries so extracted output stays valid and usable.
Memory-efficient splittingExtraction uses local browser resources to keep the flow responsive on larger documents.
Format preservationFonts, images, and core page formatting are preserved wherever possible.
Operator notes
Split PDF files without uploading the original document
Splitting PDF files is useful for extracting forms, isolating chapters, or sending only the pages someone needs. Many online tools require uploading the full document before extraction. DocuStitch removes that step for standard workflows.
When you split PDFs with DocuStitch, extraction runs directly in your browser using WebAssembly (WASM), keeping the document on your device during processing.
You can extract individual pages or ranges while keeping the flow private, browser-based, and fast.
01
Visual page selection
Select pages for extraction without moving the workflow to a remote service.
02
Range extraction
Specify custom ranges like 1-10 or 12-15 in a single run.
03
Format integrity
Preserves core page content and layout in extracted output.
04
Memory optimization
Uses local browser resources to keep extraction responsive.
