Frequently Asked Questions
What is PDF metadata?
PDF metadata consists of hidden document properties such as the title, author, subject, keywords, and creation date. This tool allows you to view and edit these specific fields directly within your browser without altering the visible text or images. Users can update these details to improve document organization or searchability while keeping the original file content intact.
Will this change the document content?
No, the tool modifies only the metadata properties like title, author, and keywords while leaving the actual text, images, and layout completely untouched. This client-side processing ensures your document content stays secure while you update its information. The modification happens entirely within your browser environment using libraries like pdf-lib, so no data leaves your device.
How does the tool handle my file privacy?
The application processes your PDF entirely on the client side using JavaScript libraries such as pdf-lib and jszip. This architecture guarantees that your file never uploads to a server, ensuring complete data security and privacy. You can edit metadata for sensitive documents with confidence knowing the data remains local to your device.
Can I preserve existing metadata values?
Yes, the interface allows you to leave specific text inputs blank to preserve the existing values for fields like subject or creator. This feature lets you update only the information you need to change without overwriting other important document details. The tool intelligently retains original data for any field you do not explicitly modify.
What are the limitations of this browser-based tool?
The client-side architecture limits functionality to operations achievable within the browser environment, such as editing standard metadata fields. Complex server-side operations or modifications requiring external processing are not supported by this specific implementation. Users should rely on this tool for quick, secure metadata updates rather than advanced document manipulation tasks.
