This PDF metadata editor is built on the OpenDataLoader open-source local PDF parsing engine. All file processing is performed offline in your browser.
1. 1. Local PDF Document Parsing: Reads the complete binary data stream, separating page content from the header metadata dictionary. All data stays in browser local memory.
2. 2. Metadata Dictionary Read/Write: Displays existing metadata for editing. Users modify or clear fields. Page content layers are never accessed or modified.
3. 3. PDF Header Structure Rewrite: Preserves all original page resources. Only the header metadata block is replaced with new user-defined metadata.
4. 4. Local PDF Export: After reconstruction, packages a new PDF with modified metadata locally. One-click download.
