PDF metadata fields
Look up the eight standard Document Info fields, typical sources, and whether this site can edit them.
Then view the values in your own file.

PDF Metadata Guides
Use these PDF metadata guides to choose a next step: inspect standard fields, understand Document Info versus XMP, or remove supported metadata. Each card is a reading path, not a second copy of the tool.
Metadata guides
Start with the field list, then the XMP split, then removal if that is still the job.
PDF metadata vs XMP
See how Document Info and XMP differ, why values can conflict, and which cleanup actually touches XMP.
Then inspect Info, document XMP, and page XMP.
How to Remove Metadata from a PDF
Compare methods, scope, and risk before you clear Document Info and detectable XMP.
Then use the scoped remover if that boundary matches.
Other PDF guides
These notes sit outside the PDF metadata topic. This site does not convert drawings to SVG, DXF, AI, or EPS.
How to Turn a PDF Schematic Sketch into a Vector File
Check whether a schematic PDF already contains vector paths, then continue in Inkscape or Illustrator.
Keep conversion in a drawing tool you can inspect.
