Is OZO really free?
Yes. Every tool on OZO is free to use, including downloading your documents as PDF. There are no paid plans. OZO is funded by ads shown around the tools (never inside your documents) and by voluntary donations.
Do I need to create an account?
No. Every tool works without an account or signup.
Where is my data stored?
Your drafts are saved only in your own browser, and PDFs are created on your device. Clearing your browser data removes them.
Can I use OZO on my phone?
Yes. OZO is built for phones first and works in any modern browser. You can also add it to your home screen to use it like an app.
Will my documents have OZO branding?
Documents have a small "Made with OZO" line at the bottom of the PDF, which helps other people find OZO. Everything else on the page is yours: your logo, colours and details.
Can I suggest a new tool?
Please do. OZO adds new tools regularly, and many come from suggestions. Send yours through the contact page.
