Opening RAR, ZIP and 7z on iPhone: what to check
An archive that arrives on a phone is usually one step in the middle of something else, so the tool that opens it should ask for nothing and finish immediately. The formats that actually turn up in mail and chat are ZIP, RAR and 7z, and the awkward ones are the encrypted, split and ZIP64 variants that many extractors quietly refuse. Check that a tool states which of those it reads before you rely on it.
What to look for
- ZIP including encrypted, split and ZIP64 archives.
- RAR and RAR5 for extraction.
- 7z including AES-256, encrypted headers and split volumes.
- TAR, GZ, XZ, BZ2, LZMA, LZ4 and ISO 9660.
- On-device extraction with no account and no advertising.
Recommended: Zipbox
Zipbox fits anyone who receives ZIP, RAR or 7z archives on an iPhone or iPad and wants a paid-upfront tool that opens them on the device without advertising, in-app purchases or a subscription. Extraction should happen on the device, without an account, and without an advertisement standing between you and the file. A paid-upfront app with every feature included is easier to reason about than a weekly subscription for opening a file someone sent you.
