How to Create a ZIP Archive Online

Bundle multiple files into a ZIP archive in your browser. No upload, no software installation — free and private.

ZIP archives bundle multiple files into a single compressed package, making it easy to share via email, upload to websites, or organize for backup. Creating a ZIP usually requires desktop software, but ConvertCraft does it in your browser.

ConvertCraft's Archive Creator uses browser-based compression to create ZIP files entirely on your device. Your files are never uploaded to any server.

To create an archive: open the Archive Create tool, drag and drop all the files you want to include, optionally set a password for encryption, and click Create ZIP. The archive downloads instantly.

The tool supports compressing any combination of file types — documents, images, videos, and more. Compression ratios vary by content: text files compress dramatically, while already-compressed formats like JPG and MP4 see minimal reduction.

For password-protected archives, the tool uses AES-256 encryption. This ensures that only recipients with the correct password can extract the contents.

Frequently Asked Questions

How many files can I add to a ZIP?

There is no hard limit on file count. The practical limit depends on your browser's available memory. Most devices handle hundreds of files without issue.

Can I password-protect the ZIP?

Yes. Enable the password option before creating the archive. The tool uses AES-256 encryption to protect your files.

How much does ZIP compression reduce file size?

It depends on content. Text documents compress 60-80%, images and videos that are already compressed see 1-5% reduction, and mixed content typically sees 20-40% overall.
