Privacy and Security
ConvertTool is built for trustworthy everyday use. When processing runs in your browser, files are not uploaded to our servers. When server-side conversion is required for certain formats, transfers use encrypted connections and files are removed after processing according to our privacy policy.

Freelancers bookmark this page because it removes the install-and-export cycle from traditional desktop converters.
When a client portal rejects an upload, rerun with different quality or resolution settings instead of rebuilding the project from scratch.
