PDF Vector Extractor
High-precision PDF vector region extractor supporting 10+ PDF structures, outputting scalable vector PDFs for RAG document preprocessing pipelines
Background
Raster PDF screenshots lose selectable text and clarity when zoomed. This tool exports cropped regions as vector PDFs.
Architecture
- Client-side Web app (
index矢量截取.htmlas main entry) - No server upload — privacy-first processing
- IndexedDB / SessionStorage for session persistence
Key decisions
- Vector PDF output instead of PNG/JPG
- Batch capture, axis locking, and keyboard shortcuts for productivity
Outcome
- Useful for academic excerpts and document archiving
- MIT licensed — see repo README
