Frequently Asked Questions
- How does browser-side image compression work?
- Our compressor loads your image into an offscreen HTML5 Canvas, resizes it if needed, and re-encodes it using custom quality compression parameters. All processing runs in your browser's active tab.
- Can I choose the compression level?
- Yes! You can drag a real-time slider from 1% (extreme compression) to 100% (original quality) and view dynamic estimated output file sizes instantly.
