A ZIP arrives by email and there's no archive tool installed — or it's a work PC where installing one isn't allowed. A browser is enough. And bundling several photos or documents into one ZIP works on the same page.
Unzipping
- 1Open the ZIP tool's extract tab and add the ZIP file.
- 2The list of files inside appears.
- 3Save just the ones you need, or everything at once.
Zipping files together
- 1Drag several files into the bundle tab.
- 2Hit zip, and a single ZIP is created.
- 3Download it and attach it to your email or message.
TipHitting an attachment limit (usually 25MB)? Shrink photos with the image compressor first, then zip.
Files never leave your device
Both zipping and unzipping run inside the browser. Payslips, contracts and other sensitive attachments never touch a stranger's server.
Unzip and zip right now, with nothing to install.
