We will convert text from webpage URLs, pasted text, and file uploads witht he extensions 'pdf', 'jpg', 'png', 'bmp', 'gif', 'txt', and 'epub'.
Your word balance is the number of words you can convert to audio before purchasing more. Words are 'spent' at the time you add an article or file to your Library, not the time you listen to it. Listening to an article multiple times does not count against your balance.
When you sign up, you get 1,500 words for free. After that, you may purchase more words on a monthly subscription or in one-time bundles. Once you have words in your account, they never expire.
If you try to convert a file without a sufficient word balance, you will be alerted that it was not fully converted, and you will be able to complete conversion with one click after you have refilled your balance.
