Privacy, accuracy and compatibility
Kaazo Tools is an online website, while supported transformations and calculations run in the browser. This architecture reduces unnecessary server uploads for many workflows. Browser memory, file format support and device performance can still affect very large files.
Always review generated metadata, structured data, calculations and marketing outputs before publishing or relying on them. SEO, local SEO, financial and advertising tools are workflow helpers; they do not guarantee rankings, revenue, approval or compliance.
