PDF files only
A PDF can contain a document Info dictionary with familiar properties such as Title, Author, Subject, Keywords, Creator, Producer, CreationDate, and ModDate. These are the fields this editor reads and writes.
Changing them does not rewrite visible page text. A PDF reader may show these values in a document-properties panel, search/catalog system, or window title depending on the reader and its settings.
Leaving one of the supported fields blank removes that key from the document Info dictionary rather than silently inventing a replacement value.
PDFs can store information outside the standard Info fields. A document may also contain an XMP metadata stream, embedded files, annotations, form values, scripts, hidden content, or other data that this editor does not inspect or remove.
The Clear Standard Fields mode therefore means exactly that: it removes the eight supported document-info values. It should not be presented or used as secure metadata sanitisation.
Creator commonly identifies the application or workflow that produced the original source content before or while it became a PDF.
Producer commonly identifies the PDF-writing software or library responsible for generating the PDF representation.
Does editing metadata change visible PDF text?
No. These document-info fields are separate from the text and graphics drawn on PDF pages.
What happens if I leave a metadata field blank?
The corresponding supported key is removed from the PDF Info dictionary when the edited copy is saved.
Does Clear Standard Fields remove every hidden detail?
No. It clears only the supported document-info fields. XMP metadata and other PDF structures are outside this tool's removal scope.
Why does the tool warn me about XMP?
XMP is a separate metadata packet that can coexist with the older document Info dictionary. Editing one does not guarantee the other has been updated.
Can I edit an encrypted PDF?
Not with this implementation. pdf-lib does not support modifying encrypted documents safely, so encrypted files are rejected instead of being opened with ignoreEncryption.
Does changing the date preserve its original time of day?
If you edit a date, this interface stores the selected local calendar date at midnight. If you do not change the field, the loaded Date value is preserved.
Will editing metadata preserve a digital signature?
Do not assume so. Saving metadata changes the PDF bytes and can affect signature validity, so signed documents should be revalidated afterward.
Is the PDF uploaded by this component?
No upload request is made by this component. pdf-lib reads and writes the selected browser File locally.
