Frequently asked questions
Is the Developer Tools free to use?
Yes. The core Developer Tools workflow is available from the browser without installing software. Some higher-volume or larger-file tasks may require a paid plan.
Do I need to create an account?
Most tools can be used without an account. Signing in is only needed for account features, subscriptions, or workflows that require saved access.
What happens to uploaded files?
Files are used only to complete the requested conversion or edit. Browser-based tools process locally where possible, and server-processed files are handled through encrypted requests.
