How to translate a PDF into English

Indy PDF Studio translates the text of your document directly in your browser. During the introductory period translation is completely free, and neither the PDF nor its text is sent to a server.

Step by step

Open the editor and click Open to choose a PDF from your device.
For a scanned document, check the OCR language and let the text be recognized first. A digital PDF usually already has a usable text layer.
Click Translate, choose the source language and English (or any other supported language) as the target. Translate the current page or the whole document.
The first time, wait for the language model to download from Hugging Face. For most language pairs it is around 650 MB, so a stable connection and enough free memory help.
Review the translation in the document, fix inaccuracies and text overflowing its boxes, then export the PDF or a Word file.

Text PDFs vs. scanned documents

In a scan the text is part of an image, so OCR has to run before translation. Blurry scans, skewed lines or tiny fonts cause errors already during recognition, so check the recognized source text as well.

Layout and translation quality

The editor works with text blocks and tries to keep their position and style. A longer translation may not fit into the original space; an orange marker warns about overflow. Machine translation can change meaning or numbers and does not replace professional or certified translation.

Supported languages

You can translate between Czech, English, German, Polish, Slovak, Spanish, French, Portuguese, Italian, Japanese, Korean, Indonesian and Vietnamese. Quality varies by language pair; Japanese is experimental.
