Unzip / Extract ZIP

What does extracting a ZIP archive do?

A ZIP archive is a compressed container holding one or more files. Extracting it, sometimes called unzipping, reverses the compression and restores the original files exactly as they were before they were packaged, so you can open, edit, or use them individually again.

Almost everyone runs into a ZIP file at some point, whether it's an email attachment, a software download, or a shared folder export, but not every device has an unzip utility readily available, especially on a locked-down work computer or a device you're just borrowing.

How to unzip a file online

Upload your .zip archive, then click Extract Files. The archive is read and decompressed entirely on your device, and the individual files inside are listed and made available to download, either one at a time or all together. There is no waiting on a server to process your upload.

You can see exactly what's inside the archive before committing to downloading everything, which is useful when you've received a ZIP file from an unfamiliar source and want to check its contents first.

Common use cases

• Opening a ZIP file received by email or downloaded from a website without installing extraction software.
• Extracting files on a device or browser where you don't have admin rights to install an unzip utility.
• Quickly inspecting what's inside an archive before downloading it fully to your device.
• Recovering individual files from a backup or project archive.
• Extracting just one or two files from a much larger archive without pulling everything down at once.

Tips for best results

Password-protected ZIP archives require the correct password to extract, so have that ready if your file is encrypted. For very large archives approaching the 100MB limit, extraction speed will depend somewhat on your device's performance, since the work happens entirely in your browser rather than on a remote server.

Why use Convert369's Unzip tool

You can upload ZIP archives up to 100MB, and everything is extracted locally in your browser, so nothing inside the archive is ever uploaded to a server. The tool is free, requires no software installation, and works on any device with a modern browser.

If an archive fails to extract, it's often because the file wasn't fully downloaded or was corrupted in transit, re-downloading the original ZIP is usually the fastest fix. For archives you trust and use often, this tool is a convenient alternative to installing dedicated extraction software just to open the occasional ZIP file.

It's worth being cautious about ZIP files from sources you don't fully trust, while this tool only extracts and lists files without executing anything, you should still be careful about what you do with the extracted files afterward, particularly if the archive contains executable programs or scripts rather than simple documents, images, or data files.

This makes it a practical fallback any time dedicated extraction software isn't installed or available on the device you're using. It's also a fast way to preview an archive's contents before deciding whether it's actually the file you need, useful when you've received several similarly named ZIP attachments and want to confirm which one has the right files before committing to a full download.
