Supports translation of PDF, Word, PPT, EPUB and other documents, covering 100+ languages. Preserves original formatting, preview partial translation and pricing first, then decide whether to translate the full text.
Translation and Document Processing
"Preview part of the document before translating the complete file. The preview range depends on the document and your available account credits. If the preview requires credits, the task page will display the cost before you proceed. Layout preservation depends on the file, fonts, and text length. Complex tables, scanned pages, and text in images may require manual review. Please check the partial preview before translating the complete document."
Understand Content, Preserve Usable Document Structure
Directory Structure Preserved
Recognizes the navigation menu and chapter hierarchy of CHM files, with content still organized by the original knowledge path after translation.
Page Link Handling
Preserves jump relationships between chapters as much as possible, reducing broken links and reading interruptions in translated help documentation.
Multi-Model Semantic Translation
Aggregates models like GPT, Claude, and Gemini to match more reliable expressions based on technical documentation, tutorial, or FAQ scenarios.
Terminology Consistency
Constrains product names, button names, and command names using a terminology database to avoid inconsistent translations of the same software concept across different chapters.
Legacy Format Compatibility
For CHM documents still circulating in enterprise and software industries, reduce the preprocessing costs of localizing legacy documentation.
Online Preview and Proofreading
Review the parsing and translation results first before deciding whether to complete the full document translation, ideal for quality control of complex help documentation.
