Removing NXPowerLite Tag information from Office files to enable re-optimization

Please note we recommend that this process is only used when advised, to avoid damaging files. Removing NXPowerLite data reduces the quality of mages in the file and could lead to images becoming unusable.

Explanation:

NXPowerLite embeds a small metadata “tag” into each successfully processed file. The tag describes the version of NXPowerLite that optimized the file and the settings that were used, and enables NXPowerLite to bypass optimizing the file on subsequent runs. Tagging allows NXPowerlite to ensure that it cannot ‘over-optimize’ images in files, ensuring that the intended original quality is not degraded. Moving or renaming files is completely safe because NXPowerLite will always read this information if it exists.

Sometimes this information needs to be overridden so that the file can be re-optimized. To follow is some steps to take to remove this data from Office files.
