Delete PDF Pages: Object Pruning vs. Visual Hiding
Most online tools merely flag pages as hidden. PDFTeq’s Sigma-Prune engine physically removes objects from the binary data stream for permanent destruction.
The Engineering of Deletion
A PDF file is a complex graph of interconnected objects. When you delete a page, our engine doesn't just "cut" the file; it performs a Tree Rebalancing operation to ensure structural integrity.
1. Unlinking
The target Page Object is permanently unlinked from the /Kids array in the Catalog Dictionary.
2. Garbage Collection
Associated resources like orphaned images or fonts are purged to ensure the smallest possible file size.
The Mathematics of File Reduction
True file size optimization is achieved when: $$Size_{final} = Size_{total} - (Size_{page} + \sum Size_{orphaned\_resources})$$

Launch Sigma-PruneSecurity: Redaction vs Deletion
If your PDF contains sensitive data, masking it is insufficient. Our engine regenerates the XREF table, making the deleted data mathematically impossible to recover once the pruned file is generated.
