The PDF in a chosen language.

Translate in the PDF toolbar offers a choice of language. The text changes where it sits. Equations, code, numbers and links stay as they were.

Translate PDF

Translates the text in place and keeps the layout. Uses AI credits.

ModelChosen model

The words change. The page does not.

Text fits its box

Each translation is drawn inside the box the original text used. If it runs long, the type shrinks evenly, down to 60 percent. If it still does not fit, the app flags it as Overflow for correction.

Maths and code are left alone

The app never sends blocks it reads as equations, formulas, code or figures. Inside the text, numbers, URLs, email addresses and inline code are locked. If one comes back changed, the app rejects that section.

The PDF's own fonts

The translation uses the fonts embedded in the PDF where they have the characters. Where they do not, Noto Sans, Noto Serif or Noto Sans JP stands in, and the review list says which.

Scans work too

The first translation of a PDF needs its text as editable blocks, and a scan has none yet. Oyren offers to make the text editable first, for scans and digital PDFs alike, then carries on with the translation. Both steps use AI credits, and the first one runs once per file.

Arabic and Hebrew are not available yet. Right-to-left layout is not supported, so the app leaves them switched off rather than getting the page wrong.

Translation runs on AI credits, the same credits as the rest of Oyren. There is no subscription.

Translation into a preferred language.

A PDF uploaded to a workspace has Translate in its toolbar. The notes, plans and apps built from it live in the same place.
