To translate a PDF from Chinese to English, upload it and choose your source language — **Chinese (simplified)** or **Chinese (traditional)**, each with regional variants — with English as the target. You get back a translated PDF with the **original layout preserved**. Scanned files work too, on a different route: the AI PDF workflow doesn't handle image-of-text pages, so you select the pdfimageonly parsing method at upload and each page goes through the **image-translation pipeline**. ### 30–60% ### longer in English than in Chinese The rebuilt PDF reflows tables, columns and text boxes to absorb the expansion instead of letting it spill. ### 100 MB ### file ceiling, with no page limit The AI PDF workflow accepts files up to 100 MB, whatever the page count. ### 15–45 min ### for a typical 10–20 page document Documents of 60+ pages take significantly longer. ## Popular PDF translation language pairs Smartcat handles high-volume pairs and long-tail requests from the same workspace. ### Spanish to English PDF Translator High volume customer and marketing content ### French to English PDF Translator Brand, legal, and support documents ### All PDF translation language pairs Every source language we support, in one place ### German to English PDF Translator Technical, legal, and compliance documents ### Japanese to English PDF Translator Product, training, and localization materials ### Script choice ### Simplified and Traditional are handled as different things A mainland business license and a Hong Kong filing differ in **character set and vocabulary**. Smartcat lists them as distinct source languages, down to the region, so you select the variant rather than trust a detector. That choice drives both recognition and translation. - [Translate PDF files now](https://smartcat.com/sign-up?chinese-english-pdf-translator-carousel) ### Segmentation ### Clauses stay whole, even without spaces Chinese is written **without word boundaries**. Smartcat segments text linguistically before translating, which is the difference between a readable English contract and word salad. - [See it in action](https://smartcat.com/sign-up?chinese-english-pdf-translator-carousel) ### Layout reflow ### The layout absorbs the expansion English output is typically **30–60% longer** than the Chinese source. The rebuilt PDF reflows text boxes and table cells so the extra length doesn't overprint or vanish — you export a finished document, not a repair job. - [Start a workflow](https://www.smartcat.com/marketplace/) ### Scanned pages ### Scanned Chinese documents need the right route Image-only PDFs (stamped contracts, certificates, older scans) run on the image-translation pipeline, which you select as pdfimageonly at upload — not auto-detected. Recognition is strongest on **clean printed hanzi**. For photos rather than a PDF, use the [scanned Chinese document translator](https://www.smartcat.com/image-translator/translate-scanned-chinese-document/). - [Review in editor](https://smartcat.com/sign-up?chinese-english-pdf-translator-carousel) ### Terminology ### Terminology holds across the whole document set The tenth supplier agreement reuses every term the first nine settled. Glossary and translation memory keep 甲方/乙方 rendered consistently as “Party A / Party B” across **hundreds of pages**. - [Get started](https://smartcat.com/sign-up?chinese-english-pdf-translator-carousel) ## Why do Chinese PDFs break most translation tools? Chinese PDFs fail in ways a generic converter never warns you about. - **□□□ boxes where characters should be** — the tool substituted a font with no CJK glyphs. - **Scans rejected as image-based files** — a supplier contract scanned in Shenzhen, red company chop stamped across the signature block. - **Traditional read as Simplified** — a filing from a Taiwan partner comes back translated as if it were Simplified, mangling terms that differ between the two. And Chinese text has **no spaces between words**, so tools that split text on whitespace hack sentences apart mid-word — 合同双方 (“both parties to the contract”) becomes something a lawyer stops trusting on page one. Then there's room: an English translation typically runs **30–60% longer** than the Chinese it replaces. In a fixed PDF layout, that overflow has to go somewhere. left Smartcat handles this at the platform level. You choose **Chinese (simplified)** or **Chinese (traditional)** yourself — down to the region — so nothing rests on a detector, and text is segmented linguistically before translation, which is what keeps a clause whole when the source has no word boundaries. The PDF is then rebuilt rather than patched: tables, columns and text boxes reflow to absorb the longer English, and seals stay as images. Every term you approve compounds in the **glossary and translation memory**, so the tenth supplier agreement starts with everything the first nine settled. Comparing approaches rather than translating a file today? Start with our guide to [document translation](https://www.smartcat.com/blog/document-translation-the-complete-guide/). left ### Simplified + Traditional Translated, variant-aware — you select the script rather than relying on detection. ### Scanned pages Handled via the pdfimageonly route you select at upload — quality follows scan quality. ### Seals and chops Kept as images; text inside a stamp is not reliably read. ### Tables and columns Rebuilt in place, reflowed for longer English text. A Misread Character Reads Like a Fact Low-resolution scans, handwriting and seals stamped over text are where **hanzi OCR struggles**, and a wrong character becomes a confident English sentence. Keep the AI draft, then put a **Chinese-English reviewer** on the sections that carry risk — same project, same file. - [Book a personalized demo](https://www.smartcat.com/book-a-demo/?chinese-english-pdf-translator) ## Translate a Chinese PDF to English in five steps Upload, select the script, review, export — from one place. ### From upload to export One workflow, five stages, one workspace. ### Upload your Chinese PDF Up to **100 MB**, any page count. If the file is scanned pages rather than a text layer, choose pdfimageonly as the parsing method in the upload dialog; **it is not detected for you**. ### Select the script **Chinese (simplified)** and **Chinese (traditional)** are separate languages, with PRC/Singapore/Malaysia and Taiwan/Hong Kong/Macau variants, plus Cantonese and Pinyin. Pick the one your document is written in. ### Get the English draft Your glossary and translation memory apply, so **names, legal terms and table headings** come out the same way every time. ### Review what matters Check the translation against the live layout, alone or with a professional Chinese-English reviewer from Smartcat's Marketplace. ### Export the finished PDF Same layout, in English. What does it cost? Every plan starts with a **15-day free trial** that includes 15,000 Smartwords and full access to translation capabilities, no credit card. Translation is metered in Smartwords — **word count, not page count** — so a 3-page scan and a [300-page manual](https://www.smartcat.com/translate-large-pdf/) are priced by what's actually in them. Full detail on the [pricing page](https://www.smartcat.com/pricing/). - [Translate PDF files now](https://smartcat.com/sign-up?chinese-english-pdf-translator) ## Built for the Chinese documents enterprises actually run on Supplier and manufacturing contracts, mainland and Hong Kong filings, technical and compliance packs, and stamped back-office scans — the files where layout and terminology carry the meaning. ### Every kind of Chinese document your team works with - **Supplier and manufacturing contracts** — the glossary keeps 甲方/乙方 rendered as “Party A / Party B” across hundreds of pages. - **Mainland, Hong Kong and Taiwan filings** — Simplified and Traditional are separate selectable languages, down to the region, so you pick the variant rather than trust a detector. - **Technical and compliance packs** — tables, columns and text boxes are rebuilt in place and reflowed for English that runs 30–60% longer. - **Scanned and chopped documents** — choose **pdfimageonly** at upload; seals are kept as images, and text inside a stamp is not reliably read. - **Handwriting and low-resolution scans** — hanzi OCR struggles here, so route those pages to a human review pass. - **Vertically set Chinese** — not supported, so hire a Marketplace translator for those files. ### Human review is a stage in the same project, not a restart Keep the AI draft and add a **professional Chinese–English reviewer** from the Marketplace to the sections that carry risk — same project, same file, nothing re-uploaded. - **Where it matters most** — low-resolution scans, handwriting and text stamped over by a seal, where one misread character becomes a confident English sentence. - **If you need a signed translation** — the translator on the project **signs the statement of accuracy** for the work they did. Smartcat facilitates the attestation as the platform, issues no certification of its own and takes on no liability for translation quality. - **If signing needs handling** — an account manager can complete it manually on the linguist’s behalf. Each authority sets its own certificate, registration and legalization requirements, so confirm those first — and [book a demo](https://www.smartcat.com/book-a-demo/) if you want help matching a translator to your deadline. ### You’re never stuck with the first version Every translation lands in a complete visual editor. Click any element — a term that reads awkwardly, a table heading that needs different wording — and say what you want in plain language, then see the change before you accept it. No designer round-trips, no re-running the job. ## How Smartcat Compares to Google Translate and ChatGPT for Chinese PDF Translation ### What you get back ### Chinese layout, tables and characters preserved on export ### Scanned / image-only Chinese PDFs ### Long Chinese documents in one pass ### Simplified and Traditional handled as separate languages ### Chinese–English human review in the same workflow ### Run the same job again next month *Image: Smartcat* ### ✓ A finished English PDF that still looks like the Chinese original ### ✓ Yes — document reassembled with tables, columns and images in place, reflowed to absorb English that runs 30–60% longer ### ✓ Yes — select the pdfimageonly parsing method at upload and each page runs through the image-translation pipeline ### ✓ AI PDF workflow takes files up to 100 MB with no page limit; 10–20 pages in 15–45 minutes ### ✓ Chinese (simplified) and Chinese (traditional) are separate source languages, down to the region — you select it, nothing is guessed ### ✓ Marketplace Chinese–English linguists reviewing against the live layout ### ✓ Projects, Chat and version history — resume and re-export ### Google Translate *Image: Google Translate* ### ~ A rough file or copyable text ### ~ Partial — formatting often lost, and longer English text overruns the cell it sat in ### ~ Limited ### ~ Per-file size and page caps ### ~ Detected rather than chosen — a Taiwan filing can come back read as Simplified ### ✗ No ### ✗ Manual every time ### ChatGPT *Image: ChatGPT* ### ~ Translated text in a chat window that you rebuild into a document yourself ### ✗ No — it returns text, not your rebuilt Chinese file ### ~ Reads many scans, but the output is still text ### ~ Chat context limits — long Chinese documents get truncated or chunked ### ~ You can tell it which script to use in each prompt; nothing is stored as a project setting ### ✗ No — you arrange review yourself ### ~ Re-prompting works, but output varies run to run ## What results do teams see?

Choose pdfimageonly in the upload dialog — **it is not detected for you**. A digital PDF with a real text layer needs no parsing choice at all. Either way you also select your Chinese variant as the source and English as the target. The layout — tables, images, columns — is rebuilt in the English output, and you can review the draft before exporting. ### Does it handle both Simplified and Traditional Chinese? **Yes — and you choose which.** Chinese (simplified) and Chinese (traditional) are separate selectable source languages, with regional variants for the PRC, Singapore and Malaysia on one side and Taiwan, Hong Kong and Macau on the other (plus Cantonese and Pinyin). Vocabulary and characters differ between them, so you select the variant your document is written in rather than relying on detection. **Vertical Chinese text is not supported.** ### Can it translate a scanned Chinese PDF? Yes, but you route it deliberately. The AI PDF workflow doesn't support image-of-text PDFs, so in the upload dialog you choose pdfimageonly as the parsing method and each page runs through the **image-translation pipeline** — the only pipeline that supports **handwritten content**. Clean printed scans work well; **handwriting and stamped-over text are unreliable** and should get a human review pass. For photos of documents rather than PDFs, use the [image translator](https://www.smartcat.com/image-translator/translate-scanned-chinese-document/) instead. ### Why does my translated PDF show boxes (□) instead of characters? That's a **font problem, not a translation problem**: the viewing font has no glyphs for the characters. - Some specialized fonts may be **substituted with similar alternatives**, and **exact font matching isn't guaranteed**. - **Bold and italic formatting** is generally preserved. - On the image side, the editor ships CJK fonts — **Noto Sans SC, Noto Sans TC, Noto Sans JP, Noto Sans KR** — so CJK glyph coverage is real. - There is **no separate font-embedding step**: source fonts are carried through and substituted where a glyph is missing. So if a recipient sees boxes, install a **CJK-capable font** in their viewer, or open the file in a reader that ships one. ### Will the English text fit the original layout? English typically runs **30–60% longer** than Chinese. Smartcat reflows text boxes and table cells during the rebuild, so the export absorbs the expansion. Extremely tight fixed layouts are worth a visual check in the editor before export. ### Is there a free Chinese PDF translator? Smartcat is **free for 15 days with 15,000 Smartwords** — full access to translation capabilities, no credit card — then paid. There is **no permanently free tier**. Genuinely free tools exist and are fine for a throwaway file; what you pay for here is layout fidelity, script handling and terminology that holds across a document set. ### Is my document confidential? Smartcat is **SOC 2 Type II compliant**. Files are encrypted in transit and at rest, workspaces are isolated per account, and access is role-based. Details on the [security page](https://www.smartcat.com/security/). ### Can I export the translated English PDF after review? Yes. Once review is complete, export the finished English PDF for delivery or distribution. ### When is this the wrong tool for a Chinese PDF? When the source fights the OCR. Accuracy on hanzi degrades quickly on: - **low-resolution scans** - **handwritten notes** - **seals stamped over text** A misread character produces a **confidently wrong** English sentence, which is worse than a blank. For documents like that, take the machine draft and add a human review pass on the sections that carry risk, or go straight to a professional Chinese-English translator. **Vertical Chinese text is not supported** at all. And for a **500-page manual** the tool is right but the route is different — see [translate large PDFs](https://www.smartcat.com/translate-large-pdf/). ### My question isn't here.
