With libmodjpeg you can overlay a (masked) image onto an existing JPEG as lossless as possible. Changes in the JPEG only take place where the overlayed image is applied. All modifications happen in the DCT domain, thus the JPEG is decoded and encoded losslessly

Compatible with all RHEL-based distributions, including CentOS, AlmaLinux, Oracle Linux, Rocky Linux, etc.
