The universal archive format — one file holding many, and one that Filemorph can unpack and inspect directly on an iPhone.
ZIP is an archive format created in 1989 that bundles any number of files and folders into a single file, optionally compressing each one to save space, which made it the standard way to send multiple files as one attachment or download long before cloud file-sharing existed. Because the format has been public and stable for decades, essentially every operating system and file manager can open a ZIP archive without additional software, unlike some of its rivals that require a specific paid tool. A ZIP file shows up constantly on a phone: downloaded software, a batch of exported photos, a project's source files, or an app's data backup all commonly arrive bundled this way, and being able to look inside one without a computer nearby is a routine need rather than a specialist one. Filemorph unpacks a ZIP archive's contents directly on the phone, or lists everything inside without extracting it first, so there is no need to guess what a download actually contains before deciding whether to open it.
iPhone, iPad, and Mac open and extract ZIP files natively through the Files app. Windows, Android, and virtually every desktop and mobile operating system built in the last two decades handle ZIP without needing separate software, since the format has been an open standard since 1989.
A ZIP archive needs extracting before any file inside it is actually usable, and on a phone it often helps to know what's inside before committing to unpacking all of it. Filemorph handles both — full extraction and a look at the contents — directly on the iPhone without needing a computer or a separate archive utility.
Filemorph converts .zip files entirely on-device on iPhone, iPad and Mac — no upload, no account, and it works in Airplane Mode.
Relevant operations in Filemorph:
No. Filemorph extracts a ZIP archive's contents directly using the Files app's built-in support, with no separate unzip app or desktop software required.
Yes. Filemorph can list a ZIP archive's contents — file names, folder structure, and sizes — without extracting anything, which is useful for checking what a download actually contains before unpacking a large archive.
Yes. Filemorph extracts ZIP archives entirely on-device — the contents are never uploaded to a server, and the operation works with no internet connection.
