Methodology & Technical Transparency
Libraries used
- pdf-lib — Core PDF construction and editing logic
- pdf.js — PDF rendering and page rasterisation
Memory strategy
After each operation, URL.revokeObjectURL() is called immediately. All pdf.js document handles are destroyed via pdfDoc.destroy(). Workers are terminated on completion or component unmount.
We do not guarantee the permanent storage of files (as we don't store them). Processing of password-protected files is not supported locally.
Key Features
Strip all standard metadata
Removes Author, Creator, Producer, Title, Subject, Keywords, and the full XMP packet in one operation.
View before you clean
All current metadata fields are displayed so you can see exactly what will be removed before acting.
Selective editing
Prefer to update rather than delete? Edit individual fields and save a version with only the metadata you intend to share.
Common Use Cases
Essential before sharing documents externally to prevent leaking author names, company software names (Producer field), or internal revision history embedded in XMP data.
Frequently Asked Questions
- What metadata does it remove?
- Author, Title, Subject, Keywords, Creator, Producer, creation date, modification date, and the full XMP metadata packet.
- Is this useful for GDPR compliance?
- Yes. PDF metadata often contains personal data (author name, email in XMP). Removing it before sharing supports data minimisation obligations.
- Can I remove only specific fields?
- Yes. Leave fields you want to keep at their current value and clear only the ones you want to remove, then save.
