After processing, these files are thoroughly deleted from the system to prevent any unauthorized access. Images undergo enhancement and are stored at a JPEG quality setting of 65%, which is typically adequate for numerous applications. Nonetheless, there is the possibility to modify the settings for improved image quality if needed, although this may lead to increased sizes of the resulting PDF files. Throughout the upload process, files are kept secure and remain in a safeguarded condition until they are permanently removed following processing. This comprehensive approach ensures that user data remains confidential and secure at every stage.
