FAQ
How does compressing to exactly 100 KB work?
The compressor re-encodes your image repeatedly, adjusting quality (or size for PNG) with a binary search until the output fits within ±2 KB of the target.
Is the image uploaded to a server?
No. Compression runs entirely in your browser; the file never leaves your device.
What if my image is smaller than 100 KB?
Then it already fits — you can download it as-is or keep the original.
