Open a ZIP
List what is inside a ZIP file and pull out only the files you want — in your browser, so the archive is never uploaded.
What it does
Open a ZIP reads your files, rearranges them and writes new ones — renamed, merged or unpacked — without changing the originals you dropped in.
When you need it
Tidying up after the fact: a folder of photos named IMG_4821, twelve monthly exports to put in one sheet, an archive somebody sent that you want to look inside before trusting it.
Limits and caveats
Everything is held in memory while it works, so a very large batch is limited by your device. The result comes back as a download (a ZIP when there are many files). Everything happens in your browser, so the file never leaves your device.
How to open a zip
- Drop the ZIP.
- See everything inside it, with sizes.
- Download the files you want.
Everything happens on this device: no file is uploaded and nothing leaves the browser.
Frequently asked questions
- Why open a ZIP here instead of on my computer?
- Mostly because you are on a phone, a locked-down work machine, or somebody else's computer — the three places where unzipping is inexplicably hard. If your own machine can do it, do it there; it will be faster.
- Can it handle a password-protected ZIP?
- No. Encrypted archives are not supported, and it says so rather than showing you a list of unreadable files. For sending something with a password, our Encrypt a File tool uses AES-256, which ZIP's own password does not.
- What about a zip bomb?
- A small archive can claim to expand to petabytes and take the tab down with it. The declared size is read from the header before anything is decompressed, and checked again against what actually came out — because the header is written by whoever built the bomb. Past half a gigabyte it refuses and says why.
- Why does it show the full path of each file?
- Because the path is part of the archive and can be hostile — an entry called ../../something is legal ZIP. Nothing here writes to your disk, and the name offered for download is flattened to a plain filename first, but you should be able to see what the archive actually said.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
