Protéger un document image avant de la partager
PROTECTION D’IMAGE by ZATAZ.COM is a free browser-based tool designed to help users protect sensitive information in images and PDFs before sharing them. The tool offers features like watermarking, masking, metadata removal, and batch processing, all while keeping the processing entirely local – no data is uploaded or stored online. It aims to mitigate risks associated with exposing sensitive details within images and PDFs, such as identifying information, addresses, and technical metadata.
PROTECTION D’IMAGE by ZATAZ.COM is a browser-based tool that provides a suite of features to safeguard sensitive information within images and PDF documents before they are shared. The core principle behind the tool is to maintain complete control over the document processing, ensuring that no data is ever uploaded, stored, or analyzed on ZATAZ’s servers. This approach prioritizes user privacy and security.
Users can add a visible watermark to identify the author, source, or origin of a photograph or document. The watermark can be customized in terms of color, opacity, size, and rotation, and can be strategically placed to make its removal more difficult. The tool also allows for the creation of masking zones, where specific areas of an image can be obscured or covered with a ‘cache’ effect, mimicking techniques used in espionage films. A zoom function up to 800% enables detailed inspection of smaller areas.
Beyond watermarking and masking, the tool removes metadata, including EXIF, GPS, IPTC, and XMP data, which can contain sensitive information like location data and technical details. It also supports batch processing, allowing users to import multiple images and PDFs, modify them, and then export them as a single ZIP archive. PDF handling includes flattening pages into a single protected PDF.
The tool’s effectiveness is enhanced by its local processing – no data leaves the user’s browser. The developers cite Filigrane Facile (filigrane.beta.gouv.fr) as an inspiration, recognizing the challenges posed by increasingly sophisticated AI tools capable of removing watermarks. Despite these advancements, the tool emphasizes the importance of manual verification before sharing any document, as AI-powered tools are constantly evolving.
