About Change PDF Line Width

Change PDF Line Width by Scalebar is a browser-based tool that analyzes the vector line widths in a PDF and lets you replace selected ranges with new values directly in the PDF content. An interactive histogram helps identify the line widths used in the drawing, making it easy to adjust graphic hierarchy without re-exporting from CAD or BIM software. Since only the vector stroke widths are modified, the original geometry and quality are preserved.

Common uses

  • Increasing thin lines to improve print readability

  • Reducing excessively thick lines for cleaner presentation drawings

  • Standardizing line weights across exported CAD or BIM PDFs

  • Correcting line width issues without returning to the source file

  • Improving the graphic hierarchy of architectural drawings

  • Preparing drawings for high-quality printing or digital publication
