The Engineering Behind Non-Destructive PDF Page Extraction
Splitting a PDF document non-destructively requires copying page descriptors without re-encoding existing image bitmaps or flattening text vectors. Each page in a PDF is represented as a dictionary node linking to a resource dictionary and a content stream.
Vector Fidelity and Font Preservation
Tools Hub's client-side splitter uses pdf-lib to selectively copy only the requested page object identifiers from the source document's catalog. All referenced embedded Type 1, TrueType, or OpenType font subsets and CMYK/RGB color profiles are copied directly, ensuring the resulting extract maintains 100% identical typographic clarity and print fidelity.
