English to Chinese PDF translator
Read an English paper, report, or manual in Simplified Chinese. Upload your PDF with English and Chinese already selected, then download a translated copy or compare both languages side by side.
Real PDF comparison
This one-page research note was written for the demo and processed by the translation worker. The Chinese PDF is the unedited output. Compare the heading, paragraphs, equation, chart caption, and reference against the downloadable English original.
This is one completed translation, not a guarantee for every PDF. The sample source is fictional; inspect important details in your own document.
Fonts, text and layout
An English PDF often relies on fonts that contain no Chinese characters. Replacing words alone is not enough: the translated page needs a font with the right glyphs, sensible line breaks, and space for the new text. The example above lets you inspect those choices in an actual file instead of judging a recreated preview.
This page starts with English as the source and Chinese (Simplified) as the target. Choose Chinese (Traditional) in the language selector if that is what your readers need. These are different output choices; review names and regional terminology after changing the target. The source language can also be switched to Detect language when a document contains more than one language.
Chinese output uses a typeface that can display the translated characters. It may differ from the English source font, and headings or paragraphs can wrap differently. Inspect punctuation, small characters, and text inside narrow table cells in the downloaded PDF. A readable Chinese page matters more than matching the exact English font metrics; the original remains available for comparison.
Research papers combine prose with symbols, variables, units, and citation markers. The translation workflow aims to retain those parts while translating the explanation around them. Use Both versions to receive a reading copy and a side-by-side copy. Compare unfamiliar technical terms, figure labels, and references with the English page before quoting the translated wording in your own work.
Choose your document
Translate a relevant chapter or article rather than a whole collected volume. Two-column pages, captions, and inline notation need a visual check after translation. If only a few pages matter, extract them first to keep the document within your page allowance and make the bilingual review easier.
Keep part identifiers, version numbers, measurements, and warnings beside their diagrams. Chinese terminology may vary by discipline, so check repeated names against the English source. A scanned manual can use OCR during translation, but faint printing and low-resolution labels need extra attention in the result.
Ready when you are
Upload a text-based or scanned PDF, or load the one-page sample in the form. Files can be up to 50 MB and 100 pages. The whole document must fit your remaining page allowance.
The languages are selected for this page. You can change them or swap the direction. Keep Both versions for reading and comparison, or choose a single output. Start the translation when you are ready.
Follow progress in the upload form. When processing finishes, download the translated or bilingual PDF and compare important wording and numbers with the source.
上传英文论文、报告或说明书，确认源语言为 English、目标语言为 Chinese (Simplified)，再开始翻译。选择 Both versions 可同时获得中文译文和原文译文对照 PDF。扫描件会在翻译流程中进行 OCR；中文字体、换行和排版可能与英文原件不同，请核对术语、公式、表格和数字。
上传英文 PDFBefore you translate
Upload the PDF in the form above. English and Simplified Chinese are already selected. Choose Translated, Bilingual, or Both versions, then start the task. Progress and download links appear in the same form. You can translate a text-based PDF directly; scanned pages use OCR as part of the translation workflow.
Not necessarily. The English font may not include Chinese glyphs, so the translated document can use another font. Font size, spacing, and line breaks may also change to accommodate the translation. Open the actual sample to see one result, then inspect your document's headings, captions, and tables after processing.
Yes. Bilingual output places each original page beside its corresponding translated page in a landscape PDF. Both versions, selected here initially, also provides a translated-only download. The original and translated text can be compared without switching documents. Interactive links and annotations may not survive the bilingual page embedding.
Yes, scanned PDFs are part of the existing OCR translation workflow. Use clear, upright pages and review names, numbers, and faint text in the result. Rotate sideways pages before uploading if necessary. This form accepts PDFs rather than individual JPG or PNG images; save document photos as a PDF first.
Translation uses your normal page allowance. Compare plans and page limits. File handling is explained in our Privacy policy.
