The Privacy Problem with Online Compressors
Many online image compression tools upload your images to their servers for processing. This means:
- Your images are stored on someone else's server
- You have no control over how long they're kept
- Sensitive images (documents, medical photos) could be exposed
- The service could be hacked
Browser-Based Compression
Our Image Compressor runs entirely in your browser:
- โ Images never leave your device
- โ No upload, no server processing
- โ Works offline after page load
- โ No tracking of your images
How It Works
Browser-based compression uses WebAssembly and Canvas API:
- Your image is loaded into memory
- Canvas API processes and compresses it
- The compressed image is offered as a download
- No network request is made
When Server-Side Might Be Needed
Browser-based compression has limitations:
- Very large images (100MB+) may crash the browser
- Some advanced algorithms are too slow in browsers
- Batch processing of thousands of images
Conclusion
Choose browser-based tools like our Image Compressor for privacy-first image compression.
