RAR is a compressed archive format developed by Eugene Roshal. It offers high compression ratios, error recovery, and encryption support. RAR is often used for splitting large files into parts and is opened using tools like WinRAR or 7-Zip.
7Z is a popular compressed archive format created by the 7-Zip software. It uses advanced compression algorithms like LZMA and supports strong AES-256 encryption, making it ideal for reducing file size while keeping data secure. 7Z files can contain multiple files or folders and are widely used for software distribution and backup.
Convert your .rar files to .7z right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your RAR files into 7Z in just a couple of clicks. No registration, no limits — and it’s 100% free.
