Our Story
Why We Built This
Traditional compression services require uploading your files to someone else's servers. We realized this creates unnecessary privacy risks and slower processing times.
We asked ourselves: "What if compression could be both more private AND more convenient?"
The Solution
By moving compression processing directly into the browser, we solved both problems:
- Privacy: Your files never leave your device
- Speed: No upload/download delays
- Reliability: Less dependent on server uptime
- Cost: We can offer it free without expensive infrastructure
Our Values
- Privacy first: Your data belongs to you
- Transparency: Clear about how everything works
- Accessibility: Free and available to everyone
- Quality: Effective compression without compromise
Technical Details
Browser Requirements
- Modern browsers: Chrome, Firefox, Safari, Edge (recent versions)
- JavaScript enabled: Required for all processing
- Sufficient memory: Depends on file sizes you're processing
Performance Factors
Your processing speed depends on:
- File size: Larger files take longer to process
- Device performance: Faster devices process files quicker
- Browser differences: Performance varies between browsers
- Available memory: More RAM allows larger file processing
How Compression Works
Our tools handle compression automatically:
- Auto Compression: Algorithms balance quality and file size based on image content
- Target Size: Compress to specific file size requirements
- Format Conversion: Convert between different image formats
- Results vary: Compression effectiveness depends on your original file
