Roshal does something radical: he designs a new compression algorithm from scratch. Not a tweak. Not a fork. A true original. He calls it — Roshal ARchive .
By allowing anyone (including competitors) to include UnRAR in their software, Rarlab made .RAR a universal format. Every competing archiver—7-Zip, PeaZip, even macOS’s The Unarchiver—can extract RAR files. But only WinRAR can create them (outside of third-party reverse-engineered tools, which are legally shaky).
The result? Estimates suggest that have used WinRAR. Fewer than 5% have paid for it. And Rarlab is perfectly fine with that.
If you have ever downloaded a file from the internet, you have touched Rarlab’s DNA. You might not know its founders. You might not know its office address. But you know the three letters it gave the world: .
In the sprawling pantheon of software, most names fade. Netscape is a ghost. Winamp is a relic played only on nostalgia drives. But then there is Rarlab —a name that sounds like a forgotten genetics lab in an Eastern European basement, yet which has outlived every tech boom and bust since the Clinton administration.
Because of . The scene, the warez groups, the private trackers—they standardized on .RAR two decades ago. Upload a .7z file and someone will complain. Upload a split RAR set and everyone nods. That network effect is nearly impossible to break. The Code That Conquered: UnRAR Rarlab’s smartest business decision was not WinRAR itself. It was UnRAR —a proprietary but freely distributable decompression library.
Rarlab’s official response to the meme status? Silence. They do not engage. They do not DMCA memes. They just keep updating WinRAR for Windows 11, ARM64, and the occasional security patch (remember the ACE vulnerability in 2019? That was a rare dark moment). As of 2025, WinRAR is at version 7.x. The changes are incremental: better RAR5 format, improved AES, support for Zstandard compression, and a dark mode (yes, it took 25 years). Rarlab’s website still looks like 1998. The download button is still honest.
Why hasn’t it changed? Because it works. And because Rarlab (the company name, a portmanteau of Roshal and lab ) operates on a philosophy alien to Silicon Valley: If it isn’t broken, do not “disrupt” it. Here is the part that makes MBAs weep and laugh simultaneously.
