Fifteen clear answers to the most-searched questions about translating PDFs online — from free previews and layout fidelity to GDPR security, mobile use, certified translations and large-document handling.
Upload your PDF on TranslaPro's translator, choose your target language, and the first 3 pages are translated free with no signup. You'll see a side-by-side preview before you decide to unlock the rest. The whole process happens in your browser session, no email or account required for the preview.
Yes — when you use a GDPR-compliant service like TranslaPro. Files are encrypted in transit (TLS 1.3), processed in isolated workers, and auto-deleted within 30 minutes. We never store the source PDF, never train AI models on your content, and never share it with third parties. Read the full security overview or our privacy policy.
The best online PDF translator preserves layout, supports 50+ languages, runs OCR on scanned files, and protects your privacy. TranslaPro covers all four — competing tools like Google Translate strip formatting, while DeepL Document caps free usage and lacks OCR for scanned PDFs.
Yes. TranslaPro re-paginates the translated text into a clean, high-contrast A4 PDF that mirrors the structure of your original — headings, paragraphs, lists and tables stay readable. We don't try to overlay translated text on top of images, which is what causes the broken layouts you see in older tools.
TranslaPro handles documents up to ~500,000 characters in a single job (roughly 200–300 pages depending on density). Larger jobs are split into parallel chunks server-side so you don't hit timeout errors common with browser-only translators.
No. Everything runs in the browser. There's nothing to install, no plugins, and no desktop app. Open the translator and it works on Windows, macOS, Linux, ChromeOS, iOS and Android with the same interface.
TranslaPro offers a free 3-page preview, pay-per-document pricing from a few euros for short PDFs, and monthly subscriptions for high-volume users. There are no hidden fees, no recurring trial traps, and refunds are honored if a translation fails. See full pricing tiers.
Yes. For confidential contracts, NDAs, financial reports or legal filings, use Legal Precision mode — it prioritizes terminology accuracy over fluency. Combined with auto-deletion and EU-hosted processing, it's safe for documents covered by GDPR, HIPAA-style confidentiality, or attorney-client privilege. See our security guarantees.
TranslaPro supports 50+ languages including English, Spanish, French, German, Portuguese, Italian, Dutch, Polish, Swedish, Arabic, Hebrew, Chinese (Simplified & Traditional), Japanese, Korean, Hindi, Bengali, Tamil, Turkish, Vietnamese, Thai, Indonesian, Ukrainian and Russian.
Garbled output usually means the translator can't read the text layer — common with scanned PDFs, image-only exports, or PDFs with embedded subset fonts. TranslaPro automatically detects this and routes the file through OCR before translating, which fixes the issue without any extra clicks.
Yes. The translator is fully responsive and works in mobile Safari, Chrome and Firefox on iOS and Android. You can pick a PDF from your Files app, iCloud Drive, Google Drive or Dropbox, translate it, and download the result — no separate mobile app required. Open it on mobile the same way you would on desktop.
If you know the password, remove it locally first (most PDF readers offer a 'Save without password' option) and then upload — TranslaPro doesn't ask for passwords because we never want to store credentials. If you don't have the password, no online translator can legally process the file. After translation, you can re-protect the output PDF in Acrobat or Preview.
No automated translation — ours included — counts as a certified, sworn or notarised translation by itself. Use TranslaPro to produce a fast, accurate working copy of the document, then have a certified or sworn translator in your jurisdiction sign it off. Many users send our output to their certifier as a starting draft to cut cost and turnaround time. See pricing.
Most short PDFs (1–10 pages) finish in under 30 seconds. A typical 50-page report completes in 1–2 minutes. Very large documents (200+ pages) are split into parallel chunks and usually finish in 3–5 minutes. You'll see live progress on the processing screen and get auto-redirected to your dashboard when it's done.
Google Translate accepts PDF uploads but strips most formatting, breaks tables, drops headers/footers, and has a strict file-size limit. TranslaPro is purpose-built for documents: it preserves structure, supports OCR for scans, handles 200+ page files, lets you pick a translation tone (general, legal, technical), and is GDPR-compliant with auto-deletion — see our security overview.
