TwinpageDocument translator for iOS
Translate the document. Keep the page.
Twinpage turns a PDF or .docx file into another language and hands it back looking like the original: tables, columns, titles and pictures stay where they were. Translation runs on your device, so your files are never uploaded.

What makes it different
Original and translation, side by side
Open the original next to the translation and check any line against its source.
A sample to judge in a minute
Try a sample contract or résumé before you bring a real file. You see the result on a document that is not yours, with nothing to upload.
Translation on the device
The built-in translator does the work on your device. Nothing is sent to a server, and once a language is downloaded it works without a connection.

Questions
Is the translation accurate enough for official papers?
It is machine translation. It is useful for understanding a document and preparing a draft, but it is not certified and does not replace a sworn translator. For contracts, court, immigration, medical or other papers that carry legal weight, have a qualified translator check the result and ask the receiving office what it accepts.
Are my files uploaded anywhere?
No. The document is translated on your device by the translator built into iOS. There is no account. The app only collects anonymous usage statistics, never the content of a document, and you can switch them off in Settings. Details are in the privacy policy.
Does it work without internet?
Yes, once the languages you need are downloaded. The download happens once and needs a connection. After that you can translate offline.
Which files can I translate?
PDF, .docx, .doc and .rtf files, and photos of paper pages taken with the camera. You get a PDF that looks like the original and an editable .docx. A password-protected file has to be unlocked first.
Will the layout always be identical?
Tables, columns, titles and pictures stay in place. Translated text is often longer or shorter than the source, so lines may wrap differently or the type may shrink a little to fit its frame. Check the result in the side-by-side view, and try the sample first.
