How does the JPG size reducer hit exact file targets?

Our algorithm conducts a multi-pass binary search over JPEG DCT quantization matrices. If reducing compression quality alone cannot meet the target size without gross visual corruption, it intelligently downsamples pixel resolution until the file fits within your required ceiling.

Is my passport photo or signature safe from data leaks?

Yes, completely. Because all compression takes place in your browser's local memory, your identity documents, signatures, and certificates are never uploaded to any server or seen by anyone else.
