What’s New

Version 1.1

If you enjoy using Carbonize, consider leaving a tip in the Tip Jar. Find it in the Preferences screen. Thanks!

## Changed

* Carbonize now defaults to a new rendering method! It's instant, offline and enables supports for custom themes and image backgrounds.

You can optionally switch back to Carbon's server-side rendering by toggling the switch in Preferences.

## Added

* I've added an option to bypass the built-in editor and skip to your default browser instead. This might help if you use Chrome and prefer to export images there, while still being able to drag code onto the Dock icon or use the Services menu.

Love it

Looks very clean, great app - Awesome for building tutorials or creating blog posts. Syntax highlighting supports a lot of languages.

Developer Response ,

Thanks for your review!

Do keep in mind that images aren't easily accessible to people with visual impairment. They won't be able to fully read your tutorials or blog posts if you don't offer an alternative (like a link to the code in a Gist). There are even ways to get Carbon-like syntax highlighting to your sites without generating an image. Might be worth a look!

Can't support long code

Beautiful app but when export long code it will fail.

Developer Response ,

Thanks for your feedback and review.

I’ve just released version 1.1 which introduces a new way to render the images. Let me know if it exports your longer snippets properly now. :)
