How to create a ZIP file
Learn how to create a ZIP archive from files and folders directly in your browser, with no uploads and no account.
Creating a ZIP bundles your files and folders into one archive that is easy to share, store, or email. Aback ZIP does it entirely in your browser: nothing is uploaded, and no account is needed.
1. Add your files
Open the Create ZIP tool and select multiple files, or drag and drop them into the drop zone. Folder selection is supported in browsers that expose it, and relative folder paths are preserved in the archive.
2. Choose a compression level
Store is the fastest option and does not compress data, which suits media files such as JPEG, PNG, and MP4. Balanced is a good default for mixed content. Maximum produces the smallest archives but takes longer.
3. Create and download
Click Create ZIP. The archive is built locally in your browser and downloaded as a standard ZIP file that opens in Windows, macOS, Linux, and 7-Zip. Your original files are never modified.
What the tool preserves
File contents are stored exactly as they are, folder structure is kept, and Unicode filenames are supported. Duplicate names are handled deterministically so nothing is lost.
Frequently asked questions
Are my files uploaded when I create a ZIP?
No. Everything runs locally in your browser on your device. Files are never sent to a server.
Can I include empty folders?
Yes. Empty folders selected through the folder picker are preserved as directory entries.
