Why Create ZIP Files in the Browser?

Creating a ZIP file usually means installing WinRAR, 7-Zip, or using the built-in OS compressor. On managed corporate devices, Chromebooks, or shared computers, installing software may not be an option. Online ZIP tools exist but they upload your files to a server first — which is a privacy risk for sensitive documents.

MiOffice creates ZIP archives entirely in your browser using the JSZip library. Your files are compressed locally, the ZIP is generated in memory, and you download the result. No file ever touches a server. This makes it safe for bundling tax documents, contracts, medical records, or any sensitive files.

Client-Side Privacy

MiOffice uses the JSZip JavaScript library to create ZIP archives entirely in your browser. Your files are read into memory, compressed using the DEFLATE algorithm, and assembled into a ZIP structure — all locally. The resulting archive is then offered as a download. No file data is ever transmitted to any server. This makes MiOffice safe for compressing sensitive documents like tax returns, legal contracts, and medical records.

Frequently Asked Questions

Are my files uploaded to a server when creating a ZIP?
No. MiOffice creates the ZIP archive entirely in your browser using JavaScript. Your files stay on your device. When you close the tab, the data is gone.
Is there a file size limit?
There is no arbitrary file size limit. The practical limit depends on your device memory. Most modern devices can handle ZIP archives up to several gigabytes.
What file types can I add to the ZIP?
Any file type — PDFs, images, documents, spreadsheets, videos, code files, and more. MiOffice compresses them all into a standard ZIP archive.
Can I password-protect the ZIP file?
Currently, MiOffice creates standard ZIP archives without password protection. For encrypted file storage, consider compressing files and then using a PDF password tool for individual documents.
