Create a ZIP
Bundle any number of files into a single ZIP archive, built in your browser and never uploaded.
Free No signup Runs in your browser — nothing uploaded
What it does
Create a ZIP reads the whole document before doing anything, so what comes back is either valid output or a specific error with the position that caused it — not a partially rewritten file.
When you need it
Usually when something has already gone wrong: a config file an application will not load, an API response that has to be read by a human, or an export that has to be checked before it goes anywhere near a database.
Limits and caveats
Key order is preserved as it appears in the input. Very large documents are limited by your device's memory rather than by an upload cap, since the parsing happens locally. Everything happens in your browser, so the file never leaves your device.
How to create a zip
- Drop the files.
- Name the archive.
- Download the ZIP.
Frequently asked questions
- Does it make my files smaller?
- A little, and for some files not at all. ZIP compresses text and documents well; photos, video and audio are already compressed, so bundling them mostly just puts them in one attachment. That is usually the reason you wanted a ZIP anyway.
- What happens to folders?
- Everything lands at the top level with a plain filename. Two files with the same name get a number added rather than one quietly overwriting the other.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
