How It Works

Create a ZIP file in three steps

Step 1
📁
Add Your Files

Drag and drop files onto the input panel or click "Browse Files". You can add as many files as you like — there are no artificial limits.

Step 2
⚙️
Choose Compression

Select DEFLATE for maximum compression (best for text files, documents, and code) or STORE for no compression (faster, better for already-compressed files).

Step 3
⬇️
Download Your ZIP

Click "Create ZIP" and download your archive immediately. The tool shows original size, ZIP size, and how much space was saved.

Why BunchTool

Why use our free ZIP File Creator?

🔒
Zero server uploads

Your files are processed entirely inside your browser using client-side JavaScript. Nothing ever travels over a network to any server.

Instant local processing

No upload queues or server wait times. ZIP creation begins the moment you click "Create ZIP" — results in seconds.

⚙️
Full compression control

Choose DEFLATE vs STORE and set the compression level from 1 (fastest) to 9 (maximum). Gives you exactly the size vs speed trade-off you need.

FAQ

Frequently asked questions

Is the ZIP File Creator free?
Yes — completely free with no file-size limits and no premium tier. All BunchTool tools are free forever.
Are my files uploaded?
No. All ZIP creation runs in your browser using JSZip. Your files never leave your device.
What's the difference between DEFLATE and STORE?
DEFLATE compresses your files using the standard ZIP algorithm — ideal for text, documents, and code. STORE adds files to the archive without compressing them, making creation faster but producing larger archives.
Is there a file count or size limit?
No artificial limits. You can add as many files as your device's available RAM allows.
What compression level should I choose?
We recommend "Default (6)" for the best balance of speed and size. Higher levels (up to 9) provide slightly better compression for text-based files but take more processing time. Already-compressed files (like JPEG, MP4, or PDF) will show almost no size difference regardless of the level.
