8 Apps That Translate Prefecture Emails Instantly
You open your inbox to find an email from the préfecture full of dense administrative French—deadlines, legal references, attachments in PDF. Missing even one detail could cost you your residence permit. Before panic sets in, remember that a handful of well-chosen apps can render those intimidating lines of French into clear English (or any language you need) in seconds.
Below is a 2025-updated roundup of eight reliable tools that translate prefecture emails instantly. Each option has been field-tested by ImmiFrance advisers and clients, so you can pick the one that best fits your device, security concerns, and budget.
Why Machine Translation Matters—but Has Limits
A quick translation lets you
- spot hidden deadlines (often 15 or 30 days),
- understand which attachments must be printed and signed, and
- decide whether you need professional legal help.
However, machine translations are not legally binding. If you must answer within a short time frame, submit court arguments, or decipher an OQTF, pair the app’s output with qualified review. (Our lawyer network can step in within 24 hours—see the CTA at the end.)
1. DeepL Translator – Best Overall Accuracy
• Platforms: Web, desktop (Windows/macOS), iOS, Android
• Price: Free up to 5 000 characters; Pro plans from €8.99/month
• Stand-out feature: Document upload (DOCX, PDF) with original formatting preserved
DeepL consistently tops blind accuracy tests for French-to-English legal language. In our side-by-side trial of a 2025 prefecture OQTF notice, DeepL captured 97 % of key legal terms correctly, versus 90 % for Google Translate. The paid plan activates “Confidential Mode,” which deletes text once the session ends—useful if you’re worried about sensitive personal data.
Tip: Drag the PDF attachment from the prefecture directly into DeepL’s web window for an instant, layout-perfect translation you can save or print.
2. Gmail’s Built-In Translate – Easiest One-Click Option
• Platforms: Gmail web, Android, iOS
• Price: Free
• Stand-out feature: Auto-detect & suggest translation banner at the top of any email
If you already communicate with the préfecture from a Gmail address, you may not need an extra app. When Gmail detects French text, a blue banner appears: “Translate message?” Click “English” and the entire thread—including quoted replies—switches language instantly. The translation stays visible on subsequent opens, so you can re-read instructions without toggling back and forth.
Privacy note: Content is processed via Google servers, which may store anonymised data to improve the model. Avoid forwarding highly personal PDFs; instead, download and translate them locally using DeepL or Microsoft Translator.
3. Outlook + Microsoft Translator Add-In – Corporate Favourite
• Platforms: Outlook desktop, Outlook on the web
• Price: Free
• Stand-out feature: Company admins can force automatic translation under a data-processing agreement (GDPR-compliant)
Many large employers in France route workers’ prefecture correspondence through corporate Outlook accounts. Installing the official Microsoft Translator add-in lets you right-click → “Translate” on any incoming message or even outgoing drafts in French. Because the service is part of Microsoft 365, companies can keep data within EU servers under enterprise agreements—often a compliance must for HR departments sponsoring work permits.
4. Microsoft Translator Mobile App – Offline Packs for Train or Flight
• Platforms: iOS, Android, Windows
• Price: Free
• Stand-out feature: Downloadable French↔English offline package (~191 MB)
Traveling abroad while your renewal is processing? Download the offline pack before boarding so you can translate prefecture updates mid-air or on the TGV without roaming fees. The app also reads text aloud, handy when you need to practice how to pronounce French jargon before calling the hotline.
5. Apple Mail + System Translate – Seamless on iPhone & Mac
• Platforms: iOS 17+, macOS Sonoma
• Price: Free
• Stand-out feature: Inline translation in Apple Mail with one tap, plus privacy-preserving on-device processing for short passages
Open the email, tap the > icon, choose “Translate” and voilà—the French turns into your system language. Short segments under ~200 characters are processed on-device; longer texts go to Apple’s secure relay servers with minimum data retention. Attachments aren’t yet supported, so combine with Files → “Quick Look” → Translate for PDFs.
6. iTranslate – Scan Paper Letters Too
• Platforms: iOS, Android, watchOS
• Price: Free basic; Pro €4.99/month
• Stand-out feature: “Lens” camera mode for instant OCR translation of printed letters
Not every prefecture message arrives by email. If you receive a postal letter (LRAR) demanding additional documents, snap a picture with iTranslate Lens. The app overlays the translation on the paper in augmented reality, so you can compare lines word-for-word. The Pro tier also offers website translation within an in-app browser—useful for form pages on the ANEF portal that still lack English versions.
7. Reverso Context – Legal Phrase Precision
• Platforms: Web, iOS, Android, Chrome extension
• Price: Free with ads; Premium from €6.50/month
• Stand-out feature: Parallel-corpus examples drawn from EU law and court judgments
Reverso shines when you stumble upon CESEDA articles or dense legal formulas. Type “En l’absence de cette pièce, votre demande sera rejetée” and Reverso shows 10–20 real bilingual examples from court rulings or EU directives. Contextual learning helps you draft an accurate reply—crucial for avoiding mistakes that could jeopardise your file. Save favourite phrases to build a personalised mini-glossary for future emails.
8. Google Translate Mobile App – Attach PDFs Directly (2025 Beta)
• Platforms: iOS, Android
• Price: Free
• Stand-out feature: New beta lets you import PDFs up to 20 MB with tables preserved
Google’s mobile app received a quiet 2025 update: tap “Documents,” choose a PDF from your phone, and the translation appears in scrollable view. During our test on a 7-page convocation au guichet, headers, bullet lists and even embedded barcodes remained intact. While accuracy trails DeepL, the convenience of translating on the go is unbeatable.

Workflow: From Inbox to Action in Under 5 Minutes
- Translate immediately. Use Gmail or Outlook if possible; otherwise copy-paste into DeepL.
- Highlight deadlines. Note any lines mentioning “dans un délai de 15 jours” or “recours sous 30 jours.”
- Download attachments separately. Translate PDFs via DeepL or Google’s new document feature to keep formatting.
- Store originals and translations together in a secure folder. You may need both for appeals or court filings.
- Escalate complex notices. If the translation references OQTF, IRTF, or “refus de séjour,” contact a legal adviser immediately. Our guide on OQTF Explained details exact appeal windows.
Security Tips When Translating Sensitive Emails
- Strip personal identifiers before using free online tools: delete your numéro étranger, address, and date of birth.
- Prefer apps with GDPR-compliant servers or on-device processing for refusals or medical data.
- Keep a local copy of the French original; courts require it if you lodge a litigation appeal.
- Never rely solely on machine translation to draft legal submissions—human verification protects you from subtle errors.

When to Call in Professional Help
Even the best AI struggles with edge cases: nuanced humanitarian grounds, medical exemptions, or contradictory instructions. If your translated email includes any of the following red flags, book a consultation right away:
- Mentions of OQTF, IRTF, or “mesure d’éloignement.”
- A demand to produce tax returns you never filed (read our guide on first-year tax filing).
- A refusal citing ordre public or minor offenses.
- A notice of missed appointment you never received (see Lost Prefecture Mail).
ImmiFrance can:
- draft formal replies in French,
- secure emergency appointments, and
- connect you with a specialised lawyer to contest negative decisions.
Key Takeaways
- DeepL and Gmail cover 90 % of everyday needs, but keep Microsoft or Apple tools as backups.
- Translate attachments separately to avoid missing fine-print obligations hidden in PDFs.
- Machine translations are a first pass—not a substitute for professional review when deadlines or legal consequences loom.
- Security matters. Use confidential modes or offline packs for sensitive documents.
- Don’t wait: if an email includes a short response window, combine instant translation with rapid legal advice.
