How layout-preserving PDF translation works

KolmoPDF preserves the original document layout throughout the translation process. Page hierarchy, column structure, formulas, and inline symbols remain intact in the translated output, instead of reducing the document to plain text before translation.

Supported languages: English, Chinese (Simplified), Japanese, Korean, French, German, Spanish, and Russian. Any pair between these 8 languages.
Formula handling: Mathematical expressions are recognized and restored after translation, not translated literally.
Image translation (OCR): Enable image translation to translate text inside charts, screenshots, and diagrams embedded in the PDF.
Output options: Translated only, or bilingual output with original and translated text side by side.
Credit cost: 2 credits per page, regardless of language pair.

PDF files only. Maximum file size: 300 MB. Maximum page count: 800 pages.
