Someone sent you a .zip and your iPhone just stares at it. Unzipper opens it — ZIP, 7Z, TAR, GZ, TGZ, BZ2, TBZ and XZ — and gets your files out in a couple of taps. Most unzip apps dump the whole archive into a folder and leave you to sort through the mess. Unzipper shows you the file list first. You see every entry, its size and its folder before a single byte is written, then tick only the files you actually want. A 400 MB archive can cost you 2 MB of storage if that is all you needed. WHAT YOU GET - Any archive you are sent opens on the spot — ZIP, 7Z, TAR, GZ, TGZ, BZ2, TBZ, XZ - The contents list before extraction, so you never unpack blind - Only the entries you tick land on your device — no wasted storage - Photos, PDFs and documents previewed in-app the second they are out - Proof a download arrived intact: ZIP CRC verification plus MD5, SHA-1 and SHA-256 checksums - Your own ZIP built from anything on your device, ready to send straight back PERFECT FOR - Anyone who just got emailed an archive and needs one thing out of it - Students pulling slides and readings out of course bundles - Developers and IT folks checking a download checksum on the move - People on small-storage iPhones who cannot afford to unpack everything WHY NOT JUST USE THE FILES APP? Files can unzip a plain ZIP, and that is where it stops. It will not open 7Z, TAR, GZ, BZ2 or XZ. It will not show you what is inside before it unpacks. It will not let you pull out three entries and skip the other nine hundred. And it has no checksum or CRC verification at all. PRIVACY Every archive is opened, extracted and hashed on your device. Nothing is uploaded, there is no account to create, no ads and no tracking. Airplane mode changes nothing. FULL ACCESS Full access unlocks unlimited extraction across every supported format, contents browsing with selective extraction, the ZIP integrity and checksum tools, and ZIP creation. Choose weekly, yearly, or a one-time lifetime unlock. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends; the lifetime unlock is a single payment. Open that archive sitting in your inbox: tap Share, pick Unzipper, and pull out just the one thing you need.
