About Crunch

Privacy-first file toolkit — compress, convert, and clean

What is Crunch?

Crunch is a free file toolkit that runs entirely in your browser. Compress images and PDFs, convert to WebP, view and strip EXIF metadata — all without uploading anything. No server processing, no accounts, no limits.

Why does it exist?

Most file tools require you to upload to a server. That means your photos, screenshots, PDFs, and documents pass through someone else's infrastructure. Your photos may contain GPS coordinates revealing your home or workplace. For sensitive files — personal photos, client work, contracts, medical records — that is an unnecessary risk.

Crunch takes a different approach: everything happens client-side. The compression library runs as JavaScript in your browser. Your images never leave your device. There is no server to be breached, no data to be leaked, and no privacy policy loopholes to worry about.

How it works

01

Drop or select images

Drag files onto the drop zone or click to browse. Supports batch processing of multiple files.

02

Browser compresses locally

The browser-image-compression library uses Canvas API and Web Workers to reduce file size without leaving your device.

03

Download the results

Download compressed images individually or as a zip file. Close the tab and everything is gone.
