About this tool
Sending a folder of files by email or chat usually means bundling them first. This tool builds a ZIP archive from the files or folder you choose, using your browser's own compression rather than a server.
Because nothing is uploaded, the practical limit is your device's memory rather than an upload quota, and large archives are not slowed down by your connection.
Supported formats and limits
- Input
- *
- Output
- .zip (application/zip)
- Output name
- The archive name you choose, with a .zip extension.
- File size limit

- In your browser. The file is not uploaded.
How to use it
- Choose files, or choose a folder to keep its structure inside the archive.
- Name the archive and pick a compression setting.
- Select Convert, then download the .zip file.
Limitations
- Folder selection uses a browser feature that most desktop browsers support but many mobile browsers do not. Where it is missing, choose the files individually.
- Dragging files onto the page works, but dragging a folder does not: the browser hands over no files in that case. Use the folder button instead.
- Empty folders are not preserved. An archive is built from files, so a folder with nothing in it leaves no trace.
- Encrypted or password-protected archives are not supported.
- Two files that end up with the same name inside the archive get a counter appended, so neither is lost.
- File timestamps come from what the browser exposes, and permissions and symbolic links are not preserved.
Frequently asked questions
- Are my files uploaded?
- No. The archive is built entirely in your browser. The files never leave your device and no request carrying their contents is made.
- When should I turn compression off?
- When the files are already compressed. Photos, video, audio, and PDFs barely shrink, so storing them without compression finishes much faster for the same result.
- Why is my archive nearly the same size as the files?
- ZIP compresses each file separately, and formats such as JPEG, MP4, and MP3 are already compressed. Text, spreadsheets, and code compress well; media does not.
- How large an archive can I build?
- Each file is limited to 250 MB, and the whole archive is held in memory while it is built, so the real limit is what your device can hold. A phone will manage far less than a desktop.
