Frequently Asked Questions
Common Questions & Answers
Clear answers about image formatting, compression standards, and privacy.
What is MozJPEG and why is it better than standard JPEG?
MozJPEG is an advanced JPEG encoder developed by Mozilla that incorporates trellis quantization and optimized Huffman tables, producing 10–15% smaller file sizes than standard libjpeg at identical visual quality.
Will MozJPEG compression remove my EXIF camera metadata?
Yes, compression automatically strips unnecessary camera metadata, GPS location data, and color space tags to protect your privacy and reduce unnecessary byte payload.
