Frequently Asked Questions
Can I translate a long technical manual PDF without splitting it?
Service manuals and specification binders often run to hundreds of pages full of diagrams. Pro and Business accept a single PDF of up to 1 GB or 5,000 pages; Basic handles 100 MB and 300 pages, Free 20 MB and 20 pages. The large PDF translator page compares the plans for big manuals.
What file formats does DocTranslator support?
DocTranslator supports DOCX (Word), PDF, XLSX (Excel), PPTX (PowerPoint), IDML (InDesign), TXT, JPG, JPEG, PNG, CSV, and JSON files. You can drag and drop files or browse your device to upload them.
How much does it cost to translate documents with AI?
Signing up is free, and on the Free plan every AI translation is paid per document: $0.005 per word, or $1 per page for PDFs and scans, with a $0.99 minimum. A subscription includes AI translation every 30 days: up to 1,000 pages on Basic (from $1.99 a week) and up to 5,000 on Pro ($19.99 a month) and Business ($49.99 a month). All plans include 108 languages and full file format support.
How many languages does DocTranslator support?
DocTranslator supports 108 languages including Spanish, French, German, Chinese (Mandarin and Cantonese), Japanese, Korean, Arabic, Portuguese, Italian, Russian, and many more.
How fast is the AI document translation?
It depends mostly on the document. A short PDF with a text layer comes back sooner than a long scan, because each scanned page has to be recognised (OCR) before it can be translated. There is no setup step before that: you upload the file, choose the two languages, click "Translate" and download the result in its original format and layout.
Does DocTranslator preserve the original document formatting?
Yes, DocTranslator maintains the original language style, formatting, fonts, and layout of your document. The AI ensures accuracy and context while preserving the natural flow of your original document across all supported formats.
Is my document secure when using DocTranslator?
Yes, all communications with DocTranslator are encrypted. Your private documents are handled with discretion, and only authorized personnel can view your files. DocTranslator has robust privacy policies in place.
Can I preview my translation before paying?
Yes, where a preview is available for your language pair. After you upload a file, DocTranslator shows its first page already translated, free of charge, before you pay; for EPUB and HTML files it is the opening section. For a fuller check, the monthly Basic plan starts with a 7-day free trial for up to 30,000 words, or you can pay for a short document on its own, from $0.99.
What's the difference between AI translation and human translation?
AI translation is instant and affordable ($0.005/word on Free, less on Pro, paid per document) and ideal for quick understanding of content. For official purposes like USCIS submissions that require certified and notarized translations, you must use human translation services.
How do I get started with DocTranslator?
Create a free DocTranslator account by signing up with your name, email, and password. Then upload your file (Word, PDF, PowerPoint, etc.), select source and target languages, click "Translate," and download your translated document.
