Do free tools require an account?
No. Public UtilityHub tools open without an account. An account is required only when you want a workspace to save records, collaborate with a team or use paid product features.
Are the public tools really free?
Yes. The tools listed in the public tools directory are free to use. They do not start a subscription and do not ask for a card.
Are my files uploaded to UtilityHub?
Image and PDF pages state how each tool processes files. Where a page says browser processing, the work happens on your device. Always check the privacy note on the specific tool before adding a sensitive file.
Should I verify a downloaded result?
Yes. Open every downloaded file and confirm its dimensions, size, legibility and destination requirements. UtilityHub helps prepare a result but cannot verify the current rules of every external form or service.
What currency are plans shown in?
Launch prices are shown in US dollars and exclude applicable taxes. Calculator currency selectors are labels only and do not perform exchange-rate conversion.
