Thanks for reaching out to us!
We haven’t yet added support for custom fonts to the new online version, however we will be adding it, along with other features like Clone, Frames and Stickers in the coming months.
In the meantime, you can download our program version from ribbet.com/download which is identical to our previous (Flash) version and has all the same functionality including Custom Fonts (click the “Load My Fonts” button at the bottom of the Text tab). The program version will continue to work well into the future. Once installed it will add a Ribbet icon to your Windows desktop / Mac icon dock – you can launch Ribbet from that (no need to return to our website). You can also sign into it with your existing Ribbet account.
Let us know if you have any further questions.
– Regards, The Ribbet Team
