VERNAM is a free, open-source file encryption tool that runs entirely in the browser. It encrypts any file with a passphrase using XChaCha20-Poly1305 and Argon2id, and no files or passwords are uploaded. It is published by PrivacyTools.io and offers an optional high security mode with heavier key derivation.
ConvertCSV.com is a collection of online tools for converting CSV and Excel data to and from formats such as JSON, XML, SQL, YAML, KML, GeoJSON, HTML, Markdown and PDF. It also provides a CSV viewer and editor, a CSV validator, SQL querying and data extraction tools. The tools run on the client side, so data never leaves the computer.
Double Commander is a free cross platform open source file manager with two panels side by side. It is inspired by Total Commander and includes an internal text editor, a file viewer for hex, binary or text formats, archive handling, extended search with full text search, and support for Total Commander plug-ins. It offers FTP, FTPS, FTPES, SSH+SCP and SFTP protocols support, a multi-rename tool and a tabbed interface.
FreeFileSync is a free open source data backup application for comparing and synchronizing files and folders on Windows, macOS and Linux. It determines differences between a source and target folder and transfers only the minimum data needed rather than copying every file. The website also references a separate Business Edition available for license extension.
Recoll is a desktop document search application for Unix, Linux, Microsoft Windows and MacOS, built on the Xapian search engine library. It finds documents based on their contents as well as their file names and can search most document formats. The software is free on Linux, open source, and licensed under the GPL.
Dangerzone is a free and open source project maintained by Freedom of the Press Foundation. It converts potentially dangerous PDFs, office documents, or images to a safe PDF. Documents are sanitized in a sandbox with no network access, and the document is converted into pixels and rebuilt as a PDF.
BackupPC is an open-source, enterprise-grade system that backs up Linux, Windows and macOS PCs and laptops to a server's disk. It includes a web interface for viewing logs and status, initiating and cancelling backups, and browsing and restoring files, plus data deduplication and compression. No client-side software is required. The latest release is 4.4.0, from June 20, 2020.
