I'm Fatih, the creator of 10015.io. I've developed one of the most popular text to handwriting converters on web. It was a though development process as it has many difficult steps like conversion of html into images and also converting them into pdf files.
One of the most requested feature of this tool was multiple page support. At first, it is not easy to figure out how to split text into multiple pages because the area of the text, line heights and fonts are all dynamic. After a long development process, I've added multipage support to text to handwriting converter on 10015.io.
Now, it automatically splits the text into multiple pages and you can download the image and PDF of each page separately or download all as a single PDF file. Here is how the output looks.
You can give it a try and comment about your thoughts about the new feature.
