Frequently Asked Questions
How does the compressor guarantee the file stays under my limit?
Our engine iteratively calculates quantization tables and compression quality until the resulting byte size is safely below your ceiling.
Will my photo become visibly blurry?
No. The compressor balances compression ratio to retain high sharpness while eliminating invisible metadata and redundancy.
