Compare SonikaAI, DeepL, VersQ and Google Translate: whether the pages still look right, whether you can translate one section, and what file you get back.
Start with SonikaAI if you need the whole PDF or just a few pages translated with the structure of the document intact. If a Word file, working in an editor or a quick free translation matters more, the table shows which service suits you better.

The competitors’ capabilities are taken from their own official descriptions. Google states that formatting is preserved only for the paid Cloud Translation API, not for the free translate.google.com compared here. This compares features, not translation quality.
In Document mode the text, tables and figures stay where they were. That makes it easier to check the translation against the original and to find the caption that goes with a diagram — there is no layout to rebuild by hand.
If you only need one section out of a large PDF, set the page range when you start. There is no need to split the file yourself.
Choose translation with narration and you get text and audio from a single run. A long report or a coursebook is something you can listen to on the move instead of reading off a screen.
Start with the pages that have tables, captions and complex layout. Look at how the translation reads and where things ended up — then decide how much more to process. To keep the original pages you need Document mode. If the PDF is above all a book to read or listen to, choose Book mode: it prepares a comfortable version of the text and may reflow the layout. SonikaAI needs a PDF with a text layer. Scanned PDFs that contain only page images are not supported at the moment.
Translate a PDF without rebuilding it afterwards — tables, figures and captions stay where they were. Do the whole file or just the pages you need, with narration if you want it.
Need one chapter out of a long PDF? Give the pages you want translated or narrated. Upload the whole file — there is no need to split it yourself.
