Dúvidas frequentes
Perguntas frequentes
Which file formats can I translate?
PDF, Word (DOCX), Excel (XLSX/XLS), PowerPoint (PPTX), EPUB, TXT and CSV. Per-file limits are 100MB without a subscription and 300MB on a paid plan (Plus or Pro).
Which languages are supported?
Popular languages are Simplified Chinese, Traditional Chinese, English, Spanish, French, German, Japanese, Korean, Russian, Arabic and Portuguese. Other languages in the full list can be translated too.
Is it really free?
Yes! Files with up to 1,000 words (characters/words) are completely free. Larger files are translated first; review the preview images, then pay only if you want the full download.
How are larger files billed?
The first 1,000 words are free. The rest accumulates by tier: 1,001–20,000 @ base rate $1.00 / 10k (¥7.00 / 10k); 20,001–100,000 @ 30% off ($0.70 / ¥4.90); 100,001–300,000 @ 50% off ($0.50 / ¥3.50); 300,001+ @ 70% off ($0.30 / ¥2.10). Rounded to the nearest cent (minimum $0.01 (¥0.07)).
Do I need an account?
No. Open the translator and start as a guest. We do not keep a cloud document library. You can sign in anytime to manage and use subscription plans.
Can I see the translation before I pay?
Yes. When translation finishes, you get preview images: the first 2 pages side by side when the file is longer than 4 pages, or page 1 when it is not. Previews are images, not the full file. Pay to download every page after you check quality and layout.
Will my formatting be kept?
Office files keep styles, tables and most layout. PDFs are semantically reconstructed so headings, lists and links are retained when the source contains real text.
How are different languages counted?
Chinese, Japanese and Korean are counted by characters. Other languages are counted by words. The base rate ($1.00 / ¥7.00 per 10,000 words), the first 1,000 words free, and the 30%, 50% and 70% tiers are the same.
Do you keep my files?
No. For Word, Excel, PowerPoint, EPUB, TXT, and CSV documents, text extraction is performed entirely locally in your browser; original files never leave your device. Due to the visual complexity of PDF layouts (involving vector fonts, dual text layers, and coordinate reconstruction), PDF documents are processed inside an isolated secure sandbox and permanently destroyed immediately after processing. We never build a cloud document library, nor do we train AI models on your data.
Am I charged if translation fails?
No. If translation does not finish, no subscription words are used and there is no download charge. You can retry.
Can I cancel a subscription?
Yes. A PayPal subscription can be cancelled any time in your account. Words already paid for remain until the current period ends, and it will not renew. A WeChat monthly pass does not renew automatically.
Which payment method should I use?
In mainland China, use WeChat Pay. Elsewhere, use PayPal.
What if my PDF is encrypted?
If the file needs a password to open, the page asks for it before estimating length or starting. You can also decrypt it locally and upload again. A locked file is not translated, and it is not treated as Chinese for the estimate.
