Many jurisdictions, courts, and academic institutions require submitted documents and pleadings to feature sequential line numbers descending along the left edge of each page. Instead of struggling with word processor templates before exporting, our tool scans your existing PDF dimensions and dynamically injects precise, professional line numbering (1 to 28+) uniformly across every page's left margin.
