Depending on what you upload
Your translated EPUB will look great and read naturally - in the clean, standard ebook style readers are used to. Chapter structure and paragraphs are preserved.
If your original has custom styling (special fonts, drop caps, complex layouts), you'll want to review and apply those in your formatting tool before publishing. Many authors go straight from BookLingua to KDP upload.
We do our best to keep your original formatting - fonts, spacing, headings, bold and italic text - so your translated file looks as close to the original as possible.
Most customers can go straight from BookLingua to KDP or print setup, but it's worth a quick review to make sure you're fully happy before going to print.

Everything you need to know before you get started
Yes - significantly. BookLingua uses a proprietary two-pass system: the first pass produces a faithful translation; the second is an editorial review that refines idioms, adapts cultural context, and ensures your book reads naturally to native speakers. Every change is highlighted so you stay in control.
EPUB, DOCX, and TXT. We recommend DOCX for best results - it gives the most accurate word count and preserves formatting perfectly. PDF is not supported as formatting is lost during conversion.
