How does the 50kb Image Compressor work?
Our tool uses a programmatic bisection search (binary search) algorithm locally in your browser. When you drop an image, the JS engine quickly generates compression tests on Canvas at varying quality levels and dimensions. In less than 150ms, it identifies the highest quality index that fits strictly below the **50 KB** threshold. No image data is ever uploaded to any servers.
Frequently Asked Questions (FAQ)
- How is quality maintained at If the file size is too big for high qualities, our script automatically scales down the resolution slightly so the photo details remain clean instead of turning into pixelated blocks.
- Is there a limit on image dimensions? No. It accepts photos of any resolution (including large mobile camera snaps) and optimizes them locally.
