About Online PDF Merging
Merging PDF documents allows you to combine separate reports, scanned invoices, certificates, or chapter files into one consolidated file. SmartToolzAI uses web-based binary parsing (`pdf-lib`) to extract page indices from each file and compile them sequentially into a single target PDF. Processing occurs locally in memory, making it lightning fast and 100% secure.
