Create one ZIP from files or a folder
Add individual files or choose a folder, review the safe relative paths, remove anything unintended, set the archive name, and create the ZIP locally. Folder structure is preserved when the browser exposes relative paths.
- Up to 500 entries and 200 MB of selected source data in the current browser workflow.
- Unsafe traversal, absolute, drive-letter, and invalid archive paths are rejected.
- Password-protected ZIP creation is not offered.
Compression savings depend on the source
ZIP can shrink text, logs, CSV, source code, and other compressible data, but JPEG, MP4, many PDFs, and other already-compressed files can stay almost the same size. Packaging many files into one archive is still useful even when byte savings are small.
- Original files are never modified.
- Input and output sizes are measured after creation.
- Open the ZIP once before deleting the source files.
Questions, answered.
How do I zip a folder online?
Choose the folder option when your browser supports it, review the relative paths, and create the ZIP. The folder contents stay in your browser.
Why is my ZIP not much smaller?
Many image, video, PDF, and modern document files are already compressed and have little redundancy left for ZIP to remove.
Can this create a password-protected ZIP?
No. Use a desktop archiver that explicitly supports encrypted ZIP creation when you need that feature.
Are my files uploaded?
No. Archive creation happens locally in this browser tab.
