Best Free ZIP Files Online

How it works

1. Select files. Choose the files you want to bundle (up to 100 MB each).
2. Set options. Optionally name the archive and pick a compression level (0–9).
3. Download ZIP. A single ZIP containing every file downloads automatically.

About this tool

ZIP Files bundles several files into a single ZIP archive you can download and share as one attachment. Select the files, optionally name the archive and pick a compression level, and the tool packs them together — handling duplicate filenames so nothing gets overwritten. It's the quick way to turn a scattered set of documents or images into one tidy download. No account, no watermark, and your files are packed in memory and discarded once the ZIP is ready.

What people use it for

• Send many files as one tidy attachment
• Bundle a set of images or documents together
• Compress a folder of files before uploading
• Package related files for sharing or backup
