How can we help?

Drag and drop your PDF into the app, or click "Choose File". Select your target language, then click "Translate PDF". The translated version will appear on the right side.

You can also translate specific pages by enabling "Translate specific pages" and entering the page range.

Apple Translate works completely offline on your device. Your documents never leave your Mac. It supports 18 languages including English, German, French, Spanish, Italian, Japanese, Chinese, and more.

Google Translate requires an internet connection and your own Google API key. It supports 85+ languages including Bosnian, Serbian, and Croatian which Apple doesn't support.

Go to System Settings → General → Language & Region → Translation Languages. Click the "+" button and add the language you need, then click Download.

Important: Enable "On-Device Mode" to ensure translations work offline and privately within Comprendo.

1. Go to console.cloud.google.com

2. Create a new project or select an existing one

3. Enable the "Cloud Translation API"

4. Go to Credentials → Create Credentials → API Key

5. Copy the key and paste it in Comprendo's Settings (gear icon)

Comprendo includes 50 free pages to try before purchasing. After that, a single one-time purchase of $1.99 unlocks the app permanently — no subscription, no recurring charges.

Open Comprendo and go to the menu bar → Restore Purchases. Make sure you're signed in with the same Apple ID you used for the original purchase.

Translated PDFs are saved to your Downloads folder with the original filename plus the target language code. For example: "document_de.pdf" for a German translation.

You can also open the translated PDF directly in Preview by clicking "Save / Open" in the top right of the translated panel.

Translation quality depends on the engine used. Google Translate generally produces higher quality results for most language pairs. If you're using Apple Translate, try switching to Google mode.

Also note that highly technical documents, scanned PDFs with poor quality text, or PDFs with complex layouts may not translate as well.

Drag and drop an image, screenshot, or PDF into the app, or click "Import". Click "Scan This Page" (or "Scan Selected" for multiple pages) and the extracted text appears in the panel on the right.

You can also use the menu bar icon for Quick Scan or Scan Clipboard without opening the main window.

No. OCR runs entirely on-device using Apple's Vision framework, and translation runs entirely on-device using Apple's Translation framework. Nothing is ever uploaded — Pic2Text works fully offline.

When you export a scan as a Searchable PDF, Pic2Text stamps an invisible, precisely positioned text layer over your original scanned image. It looks exactly like the original scan, but the text is now selectable, searchable, and indexable in Preview, Spotlight, or Acrobat.

Pic2Text includes a 3-day free trial with full functionality. After that, a single one-time purchase of $4.99 unlocks the app permanently — no subscription, no recurring charges.

Open Pic2Text and go to Settings → Restore Purchases. Make sure you're signed in with the same Apple ID you used for the original purchase.

You choose the destination each time you export — Pic2Text supports TXT, PDF, Searchable PDF, RTF, and DOCX formats.
