How much does it cost to translate EPUB?

From 249 RUB per book up to 200 thousand words on Basic, or 445 RUB on Premium. The exact price appears once the file is uploaded.

Can I check the quality before paying?

Yes. A sample of the book is translated automatically after upload so you can compare it against the original. Payment comes after that.

How long does translating a book take?

Usually from tens of minutes to a few hours depending on length. Progress is visible on the order page and the finished file arrives by email.

How is this different from machine translation?

Translation runs through large language models with surrounding context rather than word by word. The difference shows in dialogue, terminology and long descriptive passages.

Translate EPUB from Chinese to Korean

A EPUB file translates from Chinese to Korean in full, automatically. The EPUB file is split into meaning-preserving segments and translated piece by piece. The preview is free and pricing starts at 249 RUB per book.

Upload a bookPreview is free; you pay after checking the quality.

What happens to your file

The EPUB file is split into meaning-preserving segments and translated piece by piece. Markup, chapter order and structural elements are rebuilt on assembly, so you download the same EPUB format you uploaded.

How the translation runs

You upload a EPUB file and we parse its structure: chapters, markup, structural blocks.
Text is split at sentence boundaries so the model sees a complete thought rather than a fragment.
Segments are translated with neighbouring context, which keeps names and terminology consistent across the book.
Translated segments go back into the original structure and you download EPUB.

What is preserved

Translating EPUB preserves:

table of contents and chapter navigation
footnotes and endnotes
images and their captions
chapter breaks and part ordering
book metadata: author, title, language
paragraph styles and text emphasis

Chinese to Korean: what changes

Korean text usually runs about 88% longer than the source. For EPUB that means the translated file grows and pagination shifts.

This pair crosses writing systems: Han characters to Hangul. For EPUB that means embedding a font covering the target character set, otherwise glyphs render as empty boxes.

Korean does not separate words with spaces, so volume is counted in characters rather than words.

What makes translation into Korean harder:

the honorific system colours every line and encodes character relationships
the verb moves to the end of the clause, restructuring word order entirely
formal and neutral address are distinct, and a book cannot mix them
subjects are frequently dropped and inferred from context

What makes the Chinese original harder to read

Difficulty comes from the source language as much as the target. Here is what has to be untangled in Chinese text:

The original does not separate words with spaces, so phrase boundaries have to be recovered algorithmically — and that determines where the text is cut into translation segments.
Chinese originals are more compact than most languages: one character carries more meaning, so a short page can expand into a noticeably longer translation.
number is not marked grammatically, so singular versus plural has to be recovered from context
the subject is often omitted, so who is acting has to be inferred from preceding sentences

What to keep in mind

DRM-protected files cannot be opened programmatically and are not processed. We do not help remove protection.
Text length changes during translation, so pagination will not match the original.

What can go wrong

The honest weak points of this particular combination:

Pagination in EPUB will not match the original: the text length changed and EPUB reflows to the reader's screen.
Complex typesetting — pull quotes, drop caps, two-column text — carries over approximately.
In technical writing, terms can be rendered differently across chapters. If consistency is critical, use the Premium tier with its double pass.
If the translation fails, you get a full refund — the request form is on the site.

What it costs

Basic is 249 RUB for a book up to 200 thousand words; Premium is 445 RUB. The exact price is calculated once the file is uploaded and the real word count is known. A free preview shows translation quality before you pay.
