ezyZip Research Benchmarks 42 Archive Formats Spanning Four Decades

Tallinn, Estonia, July 2026 - WebbyAppy OU, the company behind the browser-based archive manager ezyZip, has published the most comprehensive practical comparison of archive formats to date. The benchmark covers 42 archive and compression formats spanning four decades, from 1984's Unix compress and 1985's BBS-era ARC to today's Zstandard and the experimental compressor paq8px. The entire study is published as an open, reproducible repository.

One Home Folder, Forty-Two Formats

The study asks the question an ordinary user actually faces: which format produces the smallest file out of a typical folder, using only the settings a non-expert would touch? Each tool ran at its defaults and at its single maximum-compression setting against a realistic 55 MB folder of text, office documents, photos and video. Every archive was extracted and verified byte-for-byte with SHA-256 checksums before its result counted. Dead Windows and DOS archivers, including WinACE, UHARC and FreeArc, were resurrected under Wine and DOSBox emulation to take part.

What the Study Found

The results tell a story of diminishing returns. ZIP reduced the folder to 82% of its original size. 7-Zip's maximum setting reached 60% in about four seconds, with the open-source Zstandard close behind at 61%. The extreme archiver zpaq produced the smallest full-corpus file at 56% but needed roughly 150 seconds. At the far end, paq8px compressed the study's text category to 17.76%, the smallest result of any format on any category, at a cost of roughly fifteen to nineteen minutes for 11 MB of text. Office documents barely compress with ZIP, at 99%, because .docx and .xlsx files are already ZIPs inside; 7-Zip squeezed the same documents to 60%. Photos and video proved near-incompressible for every format.

A 1993 PKZIP Still Works

A PKZIP 2.04g binary from 1993, run inside DOS emulation, still produced ZIP archives modern tools open, and its result on text is nearly identical to a current ZIP tool's. The 2000s Windows-only archivers FreeArc and UHARC, by contrast, deadlocked under emulation on a modern Mac and never finished. A 40-year-old open DOS format proved more durable than a 20-year-old proprietary Windows one.

"For most people the answer is wonderfully boring. 7-Zip at maximum gets you nearly all the gain in about four seconds, and after that you are trading whole minutes for a percent or two, which is a long time to hold a banana," said Ezriah Zippernowsky, spokesmonkey for ezyZip. "Open formats age well. Bananas don't."
