ZIP for Form Upload — Clean ZIP for Portals

Government portals, university submission systems, job application forms, tender portals, and bank document uploads often reject ZIPs due to size, filename issues, hidden files, or folder structure problems. This tool prepares your ZIP to meet common portal requirements: size under limit, clean filenames, no hidden files, no deep nesting, no special characters.
