Choosing an archiver: 7-Zip, Bandizip, WinRAR and the rest

All of them open ZIP, 7Z and RAR. The differences are in licensing at work, garbled file names from other countries, what the installer tries to add, and whether you need anything beyond what Windows already does.

Start with the file and the feature you need

  • Standard 7-Zip cannot open ALZ or EGG. Bandizip can extract both; distinguish receiving these formats from needing to create a new archive in them.
  • Before sending an encrypted ZIP, check the recipient’s tool and encryption support. The ZIP extension alone does not guarantee that Explorer can open it. Send a small sample first.
  • Listing filenames and previewing images inside an archive are different features. Bandizip image previews require Professional; extracting only selected files does not by itself imply that you need that paid feature.

First: is the Windows built-in enough?

Windows 11 creates and extracts ZIP in Explorer, and since the late-2023 update it also extracts 7Z, RAR and TAR. If you only occasionally open an archive someone sent you, install nothing. It stops short at password-protected archives, split archives, regional formats such as ALZ and EGG, and archives whose non-English file names come out garbled. If any of those four turns up regularly, pick one of the programs below.

How they differ

7-Zip — open source, free commercial use
Free, no adverts, and no licensing question at a company or public body. Compression with its 7Z format depends on the files and settings. It supports AES-256 password protection and split archives. In exchange the interface is plain, there is no preview, and it handles archives with garbled non-English file names poorly. It cannot open ALZ or EGG.
Bandizip — the default for a home PC
It extracts ALZ and EGG and supports filename encoding selection and extraction of selected files. Distinguish the free Standard edition from paid editions: image previews inside archives and archive repair are Professional features.
WinRAR — the only one that makes RAR
Everyone can extract RAR; only WinRAR can create it. It is paid, with a trial that never quite expires, and it is what turns up in software audits when people assume it is free. Unless you must produce RAR files, there is no reason to buy it.
PeaZip and NanaZip — 7-Zip with a better face
PeaZip is open source with a friendlier interface and many formats. NanaZip is 7-Zip repackaged for the Microsoft Store with Windows 11 context-menu integration. Both are sound choices if 7-Zip’s look puts you off.

Compared where it matters

Garbled file names
ZIPs made on a Mac or by older software in Korea, Japan or China arrive with file names turned into "ã…" and similar. Bandizip detects the code page and usually extracts them intact, and lets you pick one if not. 7-Zip is weak here, so if you receive such files often, keep Bandizip alongside.
ALZ and EGG files
These Korean formats extract with Bandizip; you do not need ALZip for that. Creating them needs ALZip, but since the recipient may not have it, make ZIP or 7Z instead.
Password-protected archives
AES-encrypted ZIP and encrypted 7Z require an archive application that supports them. They do not open in every application, including Windows File Explorer. Ask the recipient to open a sample first. To hide file names, check the header-encryption option in 7Z; encrypting a ZIP alone does not hide its names.
Packing a large folder quickly
Time and archive size depend on the files, format, settings and PC. We have not benchmarked these products under matching conditions, so this guide does not rank them by speed or size. For already-compressed video and photos, consider the "Store (no compression)" option.
Work PC
7-Zip or Bandizip. WinRAR only with a purchased licence, and Korean ALZip only with one too. This site’s "Work PC" template includes 7-Zip.

So which one

  1. Home PC, just one → Bandizip or 7-Zip

    Choose Bandizip for ALZ/EGG extraction and filename encoding controls; choose 7-Zip for common archives without ads. Image previews inside Bandizip archives require Professional.

  2. Work PC → 7-Zip (or Bandizip)

    Nothing to check on licensing. If garbled file names are a daily thing, Bandizip is fine too — its free edition is permitted at a company.

  3. You must produce RAR → WinRAR

    The only program that creates it. Buy the licence if it is for work.

  4. If you installed two

    They fight over file associations. Decide which is primary and set the associations in that program’s settings; use the other from the right-click menu when needed.

What rides along in the installer

Bandizip’s installer may offer other Bandisoft products; ALZip may offer related products. 7-Zip and PeaZip bring nothing extra. This site’s installer file uses the vendors’ official downloads, but the ticks on an install screen are yours to clear.

Frequently asked

It says the archive is damaged

Most often the download was cut short, so download again first. If the fresh copy is the same, 7-Zip’s "Test archive" shows which files are broken and you can extract the rest. A split archive will not open if even one piece is missing.

Can I open an archive without knowing the password?

No. Password protection exists precisely so it cannot be opened without one, and "password recovery" tools merely guess repeatedly, which is hopeless against a long password. Asking the sender is the only route.

The other person cannot open my 7Z file

7Z opens in Windows 11’s built-in extractor and in most archivers, but old PCs and phones may fail. For a file anyone can open, make a ZIP.

A __MACOSX folder appears when I extract a ZIP from a Mac

It is metadata the Mac added. Delete it. Bandizip has a setting to skip it on extraction.

How intrusive are the adverts in free Bandizip?

A single banner at the bottom of the window after an operation finishes; no pop-ups, no install prompts. If it bothers you, buy the paid edition or use 7-Zip.

Compare the archivers and download

Each archiver’s page lists its licence scope with the date it was checked, and what to set up again after a reformat. Pick them along with the rest of your programs and they install in one go.
