Rarlab is the home of WinRAR and RAR archivers. WinRAR is an archive manager that can back up data, reduce the size of email attachments, open and unpack RAR, ZIP and other downloaded files, and create new RAR and ZIP archives. A trial version is available for download before purchase.
PeaZip is a free, open-source file archiver utility for Windows, macOS and Linux. It opens and extracts RAR, TAR and ZIP archives and supports more than 200 formats. The software is built on 7-Zip, Zstandard, FreeArc, Brotli and PAQ compressor technologies. It adds two-factor authentication with a password and keyfile for formats supporting encryption, and it is natively portable.
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.
OpenMyFiles is an online file information directory. It provides categorized listings of file formats and associated programs, with top categories including archive, audio, data, raster image, spreadsheet, executable, vector image and video files.
Bulk Rename Utility is a free file renaming program for Windows. It renames multiple files and folders according to flexible criteria, such as adding text, replacing numbers, converting case and adding auto-numbers, with a detailed preview before renaming. It is free of charge for personal, private use at home; business or commercial use requires a commercial license.
Encoding Converter is an online tool for batch converting files from any encoding to any encoding. It accepts a single file, many files, or .zip files. Specifying the original encoding is optional but recommended.
MetaStrip is a browser-based tool that removes metadata from photos, videos, PDFs and documents, including GPS, camera and author details plus AI tags and C2PA Content Credentials. It runs entirely client-side, so files are not uploaded, and reads metadata locally with libraries such as piexifjs and pdf-lib. It supports batch processing of up to 100 files and is open source under MIT.
