Frequently Asked Questions
How does target KB compression work?
Our smart algorithm executes an iterative binary search across compression tables and canvas scaling, ensuring the resulting image stays under or directly matches your required KB size without blurring.
Is there any quality loss?
The compressor utilizes modern DCT quantization and sub-sampling to eliminate invisible metadata and high-frequency noise, preserving visual clarity while reducing file size by up to 85%.
Are my private photos uploaded to external servers?
No. All compression is executed entirely client-side within your browser. Your images never leave your device.
