A: Hi punkrose123,

Thanks for your question. The largest we offer is 125mb and yes, it certainly is. We have users with hundreds of pages and it works well. Just to note, if a PDF is particularly large in file size it is usually a print ready file. We do not advise using these in the system due to the size and unnecessary information they contain which will impact the conversion. It is best to optimise the PDFs for digital distribution and web view for maximum compatibility across all devices.

We can supply export settings for InDesign and help/advice for many other platforms so you can get your books looking their best!

Thanks
