A tool for redacting PDF files and images
Project description
CoverUP PDF Redaction Software
CoverUP is a free software, developed in Python, designed to provide a secure and straightforward method for redacting PDF files. It enables users to conceal sensitive text passages by overlaying them with black or white bars.
Users can import PDF documents into CoverUP, which are then converted into images. This conversion process ensures that the text cannot be copied from the document or indexed without OCR, enhancing the security of your information. Additionally, invisible layers within the PDF are not converted, providing an extra layer of security.
It also supports the import of PNG and JPG files, in addition to PDFs.
Given that image-based PDFs can become quite large, CoverUP offers two modes: a high-quality mode that maintains the visual fidelity of the document, and a compressed mode that reduces file size at the expense of some visual quality.
Whether you're dealing with a single page or an entire document, CoverUP provides a flexible and easy solution for all your PDF redaction needs.

Schwärzen von PDF Dokumenten mit CoverUP
CoverUP ist eine kostenlose Software, die in Python entwickelt wurde, um eine sichere und unkomplizierte Methode zur Schwärzung von PDF-Dateien bereitzustellen. Sie ermöglicht es den Benutzern, sensible Textpassagen zu verbergen, indem sie diese mit schwarzen oder weißen Balken überlagern.
Benutzer können PDF-Dokumente in CoverUP importieren, die dann in Bilder umgewandelt werden. Dieser Umwandlungsprozess stellt sicher, dass der Text nicht ohne zusätzliche Texterkennung kopiert oder indexiert werden kann, was die Sicherheit der Informationen erhöht. Zusätzlich werden unsichtbare Schichten innerhalb der PDF nicht konvertiert, was eine zusätzliche Sicherheitsebene gegen versehentliche Veröffentlichung bietet.
Es unterstützt auch den Import von PNG- und JPG-Dateien, zusätzlich zu PDFs.
Da bildbasierte PDFs recht groß werden können, bietet CoverUP zwei Exportoptonen an: einen Modus in hoher Qualität, der die visuelle Genauigkeit des Dokuments weitestgehend beibehält, und einen komprimierten Modus, der die Dateigröße der exportierten PDF-Datei auf Kosten von visueller Qualität reduziert.
Ob Sie mit einer einzelnen Seite oder einem gesamten Dokument arbeiten, CoverUP bietet eine flexible und einfache Lösung für alle Ihre Bedürfnisse zur Schwärzung von PDFs.
