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.

Metodologia e Transparência Técnica

Bibliotecas utilizadas

pdf-lib — Lógica principal de construção e edição de PDF
pdf.js — Renderização de PDF e rasterização de páginas

Estratégia de memória

Após cada operação, URL.revokeObjectURL() é chamado imediatamente. Todos os handles de documentos pdf.js são destruídos via pdfDoc.destroy(). Os workers são encerrados na conclusão ou desmontagem do componente.

Não garantimos o armazenamento permanente de arquivos (pois não os armazenamos). O processamento local de PDFs protegidos por senha não é suportado.

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.
