How much does it cost to translate PDF?

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.

Will the formatting survive?

Yes, layout is preserved page by page: text is replaced in place while images and tables stay where they were.

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 PDF from Korean to Chinese

A PDF file translates from Korean to Chinese in full, automatically. PDF runs through a layout-preserving engine: text blocks are replaced in place at their original coordinates while images and tables stay put. 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

PDF runs through a layout-preserving engine: text blocks are replaced in place at their original coordinates while images and tables stay put. You get a PDF back, not a rebuilt text document.

How the translation runs

We break the PDF into text blocks and record the coordinates of each one on the page.
We check whether the file has a text layer. If the pages are images, there is nothing to translate and we warn you before payment.
Each block is translated and placed back at its original position; images, tables and running heads are left untouched.
A PDF is assembled with the same page-by-page structure as the original.

What is preserved

Translating PDF preserves:

page-by-page layout and block positions
images and their captions
tables
chapter breaks and part ordering

Korean to Chinese: what changes

Chinese text usually runs about 47% shorter than the source, so the translated file ends up more compact.

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

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

What makes translation into Chinese harder:

plurality is not marked grammatically and must be recovered from context
subjects are frequently dropped and inferred from context

What makes the Korean original harder to read

Difficulty comes from the source language as much as the target. Here is what has to be untangled in Korean 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.
Korean originals are more compact than most languages: one character carries more meaning, so a short page can expand into a noticeably longer translation.
honorific suffixes encode relationships between characters; ignoring them strips a layer of meaning from dialogue
the verb sits at the end, so the meaning of a sentence only resolves at the last word
politeness level is grammatically encoded and has to be recognised to keep the register right
the subject is often omitted, so who is acting has to be inferred from preceding sentences

What to keep in mind

If the PDF is made of scans with no text layer, there is nothing to translate. We check for this before payment and warn you on the order page.
Text length changes during translation, so pagination will not match the original.

What can go wrong

The honest weak points of this particular combination:

The PDF is built from photographs or scanned pages. There is no text layer, so there is nothing to translate — we detect this in advance and show a warning on the order page.
Translating into Chinese needs characters the original PDF fonts do not carry. We embed a suitable font, but the typeface in translated blocks may differ from the original.
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.
