Frequently Asked Questions

Are AI-translated legal documents legally valid?

AI translations are fine for internal review, research, and early drafting. But courts, immigration offices, and government authorities usually do not accept AI translations as official records. If a document must be filed, certified, notarized, or used in a legal proceeding, you’ll need a certified human translation.

When is a certified translation required?

You’ll need a certified human translation for documents such as court filings, visa and immigration submissions, notarized statements, and anything that must meet a regulatory standard. Certified translators can attach a signed statement confirming accuracy, which is something AI cannot provide.

Can I rely on AI for sensitive or high-risk legal documents?

Not for official use. AI is helpful for early understanding, cross-border communication, and internal decision-making, but it should not be the sole source when accuracy has legal consequences. Always check whether the receiving authority requires a certified translation before submitting anything.

What are the risks of translating legal documents with AI?

AI may misunderstand outdated clauses, local legal terminology, or context-specific meanings. It can also miss small details such as tense changes or technical phrasing that alter the meaning of a clause. These risks matter more in regulated or formal settings, which is why certified human review is required for official use.

Is AI translation safe for confidential legal information?

Smallpdf uses encrypted transfer, GDPR-compliant processing, and automatic file deletion to protect your documents. Because legal documents often contain sensitive information, AI translation is appropriate for internal use, but official filings should go through certified translators who follow jurisdiction-specific requirements.

Can AI translate scanned legal documents?

Yes. Smallpdf uses OCR to extract text from scanned or image-based files so they can be translated. The results depend on scan quality—blurry, handwritten, or low-resolution pages may need cleanup before translation.

Can I use AI to translate contracts for cross-border business?

Yes, for early analysis, internal alignment, and preparing drafts. It’s a good way to understand clauses, identify issues, and brief legal teams. For signing or submitting final documents, get a lawyer and a certified translator to review the final wording.

Why shouldn’t I use AI translation for court documents?

Courts require certified accuracy, consistent terminology, and an accountable translator. Because AI cannot swear an affidavit of accuracy or guarantee jurisdiction-specific phrasing, its output is not accepted as an official record.

Can AI help me summarize a long legal document instead of fully translating it?

Yes. Smallpdf offers a summary option that gives you the main points without translating every word. This is useful for early understanding, quick reviews, and comparing versions before requesting a full translation.

What if the AI translation looks wrong or unclear?

You can use the built-in AI chat to ask about unclear clauses, phrasing, or terminology. For anything that affects your legal rights or responsibilities, get a qualified legal professional or certified translator to review the document.
