Zip & Unzip Files
Bundle multiple files into a single .zip archive, or extract files from an existing zip — all processed locally in your browser. Nothing is uploaded to a server.
How to Use This Tool — Q&A
Does this upload my files anywhere?
No. Zipping and unzipping both happen entirely in your browser using JavaScript — your files never leave your device.
Is there a file size or count limit?
There's no hard limit, but very large batches depend on your device's available memory since everything is processed locally rather than on a server.
Can I zip folders, not just individual files?
This tool accepts individual file selections. If your browser's file picker supports folder selection, dropped folder contents will typically be flattened into individual files in the zip rather than preserving the folder structure.
What if my zip file is password-protected?
Password-protected or encrypted zip archives aren't supported — this tool works with standard, unencrypted zip files only.
