About adarsus

MetaClean Web Service, operated by Adarsus Technologies S.L., removes hidden metadata and data from files. The homepage lists Exif, GPS, IPTC, XMP and document metadata among the types it handles. According to the homepage, the service deletes metadata rather than anonymising it, and the rest of the file content is not affected. It processes metadata in signed PDF documents while preserving content integrity and electronic signature validity. It supports more than 100 file types, including office documents and multimedia files, and can process files in ZIP and 7ZIP format.

The homepage also describes a MetaClean API that can search, query, modify or add standard and custom metadata, and browser extensions for Gmail and Outlook that remove metadata from attachments. The homepage states that processed files are not stored longer than necessary to process metadata, and it refers visitors to the operator for more information. It lists compliance with GDPR and ISO-27001 among other regulations, but this entry does not confirm compliance. The homepage does not state pricing.
