2. What Is PDF Metadata & Why Should You Clean It?

PDF metadata contains background properties embedded into the document file structure during creation. This includes author names, corporate affiliations, computer usernames, editing software versions, and exact creation timestamps. When publishing legal filings, corporate proposals, resumes, or academic research, cleaning this hidden metadata prevents unintentional data exposure and preserves document privacy.

3. Supported Metadata Fields

Document Title: The official display title shown in PDF readers, browser tabs, and search engines.
Author / Creator: The name of the person or organization who drafted the document.
Subject: A brief synopsis or category describing the contents of the document.
Keywords: Search terms and thematic tags indexing the PDF.
Creator Application: The software used to write the original document (e.g. Microsoft Word, LaTeX, InDesign).
PDF Producer: The conversion engine or library that generated the PDF binary.
Creation & Modification Timestamps: The exact dates and times when the document was initially created and last revised.

4. 100% Client-Side In-Browser Privacy

Unlike traditional cloud converters that upload your confidential files to remote processing queues, ZechKit inspects and compiles PDF metadata entirely within your browser using WebAssembly and client-side JavaScript (pdf-lib). Your files never leave your computer or device.
