What an ebook looks like once FileConcat has read it

A two-chapter sample guide. The chapters come back in reading order; each picture is named by the text the book gives it, not described.

Sample ebook, read by FileConcat 2.9.

What gets lost converting documents to text

A shelf of books, one file to paste

Drop a folder of ebooks and they come back as one text file, each under its own name, with a token count for the whole set. An assistant that caps attachments counts it as one.

Common questions

Is my book uploaded to a server?

Not to us. FileConcat reads the book in your browser and there is no account to create. The only upload is the one you choose to make, when you paste or attach the text at your assistant.

Does it read Kindle books?

A .mobi or .azw3 file without DRM, yes, read the same way as an EPUB. A book protected by DRM is not opened.

In what order do the chapters come?

In the reading order the book itself sets. A part the book keeps outside that order is marked where it stands.

Can I get plain text without tags?

Yes. Set Format to Plain before you copy or download. The tags go, and each file sits between two rules with its name, under a short summary and the file list.

Can I convert many ebooks at once?

Yes. Drop several files or a whole folder. They come back as one text file with each book under its own name, so an assistant that limits attachments takes them as one.
