About Us
pdfclnr is a privacy-focused PDF toolkit designed to detect, remove, and manage hidden metadata in PDF documents before they are shared.
Many PDF files contain internal metadata layers such as document identifiers, creation and modification timestamps, author information, software signatures, XMP metadata, page-level data, thumbnails, and other embedded structures that are not visible in the document itself. These elements can unintentionally expose information about a document's origin, editing history, or production environment.
pdfclnr provides a structured workflow for sanitizing and preparing PDF files. The platform offers both Safe Clean and Custom Clean modes, allowing users to remove standard metadata fields or selectively target deeper internal structures such as Document IDs, embedded files, thumbnails, and page-level metadata.
In addition to metadata cleaning, pdfclnr includes a set of practical PDF utilities such as Merge, Split, Compress, and Edit Metadata, enabling users to modify and prepare documents within the same environment.
To maximize privacy and security, pdfclnr performs processing directly in the user's browser using client-side execution. Files are never uploaded or stored on external servers, ensuring that sensitive documents remain under the user's full control.
Our goal is to provide a simple, transparent, and reliable way to ensure that the documents you share reveal only the information you intend to share.
