Frequently Asked Questions
Who can access this feature?
How do I ensure the best translation?
Since translations are processed locally on your device, the language data should be stored locally. If it isn't, a simple system prompt will appear. Just follow those instructions to download the language, and you're good to go!
Can I translate large PDF files?
You can translate large PDF files, there's no set limit. Hardware limitations might cause issues with bigger documents on older devices.
Can I translate scanned PDFs or images within PDFs?
You can translate images within PDFs using the Mac version of PDF Expert, but only after running OCR to recognize the text. This is not possible on iPhone or iPad.
Will the original layout and formatting of my PDF be preserved after translation?
No, the original layout and formatting will not be preserved.
Can I translate a PDF into multiple languages at once?
You can translate a document into multiple languages, but only one at a time, not in a parallel process.
Why can’t I find the Translate icon on iPhone/iPad?
On mobile, translation is available under … → Translate PDF, not in the main toolbar.
*PDF Expert supports all languages currently available through Apple’s Translation framework. Some language-specific constraints apply — for example, translating from Arabic is supported, while translating into Arabic is not. For Mandarin Chinese, Japanese, and Korean, only horizontal text orientation is supported.
Apple updates language availability over time, so supported languages may evolve with future OS releases.
