How to metadata
Read everything a document quietly records about itself — title, author, page count, creation and modified dates, and the app that produced it. Bytefuse returns it all as clean JSON, so you can audit files or feed the details straight into a pipeline.

Why Bytefuse

See the hidden details

Clean JSON out
Get every field as tidy, predictable JSON that slots straight into audits, dashboards or downstream processing.
Private by design
Your file travels over an encrypted connection, is used only for this request, and is deleted within an hour.
