How to Translate Documents With AI

By DocFila Team · February 13, 2026 · 5 min read

In an increasingly connected world, you regularly encounter documents in languages you do not read — immigration forms, business contracts, academic papers, medical records, or travel documents. Professional human translation is priced per word and usually takes days. AI-powered document translation bridges the gap, giving you results in minutes that are good enough for understanding and reference, though not for submission.

When You Need Document Translation

Document translation is not just for language professionals. Here are the most common real-world scenarios:

Immigration and Visa Applications

Immigration authorities often require translated copies of birth certificates, marriage certificates, diplomas, bank statements, and criminal background checks. While official certified translations may be required for submission, an AI translation helps you understand documents you receive in a foreign language and prepare your own materials.

International Business

Contracts, invoices, proposals, and correspondence from international partners may arrive in languages your team does not speak. Quick translation helps you understand the content, respond faster, and make informed decisions. For final versions of legally binding contracts, always use a professional human translator.

Travel

Hotel confirmations, rental agreements, insurance documents, local regulations, and restaurant menus — when traveling abroad, being able to translate documents on your phone is invaluable.

Academic Research

Research papers, journal articles, and historical documents in foreign languages are common in academia. AI translation lets researchers quickly assess whether a paper is relevant before investing in a full professional translation.

Medical Records

If you receive medical care abroad or need to transfer records between countries, quick translation helps you understand diagnoses, prescriptions, and treatment plans.

How to Translate Documents With DocFila

Step 1 — Import or Scan Your Document

Open DocFila and either import an existing PDF or image file, or use the document scanner to capture a physical document. DocFila opens common formats such as PDF, JPG and PNG.

Step 2 — Run OCR (For Scanned Documents)

If your document is a scanned image (the text is not selectable), run OCR first. DocFila runs OCR on your device for Latin, Chinese, Japanese, Korean and Devanagari text, and the PDF translator skips pages that have no text layer, so run OCR on a scanned document before you translate it. It is not needed for PDFs that already contain text.

Step 3 — Select the Translate Tool

Tap the translate option. Choose the source language (or select "Auto-detect" to let DocFila identify it) and the target language. The text translator offers 47 target languages and Translate PDF offers 20, including:

• English, Spanish, French, German, Italian, Portuguese
• Chinese (Simplified and Traditional), Japanese, Korean
• Arabic, Hindi, Turkish, Russian, Polish, Dutch
• Swedish, Norwegian, Danish, Finnish
• …and others: 47 languages in total for text and 20 for PDF translation; the list in the app is the authoritative one

Step 4 — Review the Translation

DocFila shows the translation with the original text. Review the output and make manual edits if necessary. AI translation excels at general content but may need adjustment for:

• Technical or industry-specific terminology
• Legal language with precise meaning
• Idiomatic expressions and cultural references
• Proper nouns and brand names

Step 5 — Export the Translated Document

Save the translation as a bilingual PDF — the original text followed by its translation, page by page. The layout of the original is not preserved. Share it via email or your DocFila library, or keep it in the Secure Vault.

Tips for Better Translation Accuracy

1. Start with a clean scan. OCR accuracy directly affects translation quality. Use good lighting and the Black & White filter for text documents.
2. Proofread OCR output first. If OCR misreads a word, the translation will be wrong. Correct any OCR errors before translating.
3. Specify the source language. Auto-detection works well for major languages but may struggle with closely related languages (e.g., Norwegian vs. Danish). Select manually when you know the language.
4. Translate section by section. For long documents, translating smaller sections produces better results than feeding the entire document at once.
5. Use AI translation for understanding, certified translation for submission. AI translation is perfect for personal comprehension. For legal submissions, immigration applications, and court documents, use a certified human translator.

Privacy and Security

When translating sensitive documents — financial statements, medical records, legal contracts — privacy matters. Many online translation tools process your text on remote servers, where it may be stored or used for training. DocFila prioritizes privacy:

• Documents travel to DocFila's servers encrypted in transit, and stored files are encrypted at rest
• Translation uses cloud AI: the text is sent to Google's Gemini through DocFila's servers. DocFila does not train any model on your documents (see AI data handling)
• If a document must not leave your device, do not translate it with DocFila: there is no on-device translation mode
