Apchukso ~/zip● No upload · No install
Unzip files online right in your browser, or bundle several files into one ZIP. Garbled Korean filenames get fixed automatically, too.
The most common case is a work computer. A client sends files in a ZIP, but security policy won't let you install archive software like Bandizip or ALZip. Instead of filing a request with IT and waiting just to open one file, drag the ZIP onto this page and get the files out right away.
The second is garbled names. Korean filenames in a ZIP made on Windows can turn into a mess of unreadable symbols when unzipped on a Mac, and files sent from a Mac can show up on Windows with every Korean character split into separate letters. The moment Apchukso opens a ZIP, it checks how the names were written and fixes the broken ones before showing them. Junk that macOS quietly slips in, like the __MACOSX folder and .DS_Store files, is hidden by default. Download the ZIP again with the fixed names, and they won't break when you pass it on.
It works the other way, too. Sending one ZIP is easier on the recipient than attaching ten files to an email. Drag in several files or a whole folder, and everything is zipped with the folder structure inside intact. ZIPs made here store filenames in today's standard encoding, so even Korean names stay intact whether they're opened on Windows or Mac.
Q. Do I need to install Bandizip, ALZip, or other unzip software?
No. Any modern browser such as Chrome, Edge, or Safari works right away, with nothing to install. You can use it even on work or school computers where installing programs is blocked.
Q. Why do Korean filenames get garbled?
Because there are two ways of storing filenames. Older ZIP programs on Windows write names in a Korean-only encoding (CP949), while Macs and newer programs use the universal standard (UTF-8). If the receiving side reads them the other way, the names come out garbled. Apchukso checks which encoding each name was written in and reads it the right way.
Q. Why do Korean letters look split apart in files from a Mac?
Because a Mac stores each Korean character as separate pieces (a consonant, a vowel, and so on), and Windows shows those pieces as they are instead of joining them back together. Apchukso joins the pieces back into whole characters when it extracts the files.
Q. Can I unzip password-protected ZIP files?
Not on this page yet. When you add a password-protected ZIP, a button appears that takes you to the RAR/7Z extractor, where you can enter the password and extract it.
Q. Can it extract RAR, 7Z, ALZ, or EGG files?
ALZip EGG files (.egg) can be extracted with our EGG extractor, and RAR/7Z files with the RAR/7Z extractor. Add one here and you'll be sent to the right tool. ALZ, ALZip's older format, isn't supported yet.
Q. Can I extract a whole ZIP into a folder at once?
In Chrome and Edge, click "Extract all to folder" and pick where to save, and everything is extracted with the folder structure intact. In other browsers, click "Download" on each file, or download the ZIP with fixed names and extract it on your computer.
Q. Are my files uploaded to a server?
No. Apchukso has no server that receives files. Reading and extracting ZIPs, and creating new ones, all happens inside the browser you're using right now.
Q. Is there a file size limit?
Nothing is sent to a server, so there's no server-side limit. But because the browser loads files into memory to process them, ZIPs of several GB may slow down or stop partway. In that case, split them up or use a desktop ZIP program instead.
