How to Translate Selected Text in a PDF on Mobile Devices
Question details
The user wants to translate specific portions of text directly from the pop-up context menu while reading a PDF document on a mobile device.

- Product
- Acrobat Reader Mobile
- Device & OS
- not provided
- Scenario
- Reading a PDF file on a smartphone or tablet and attempting to translate a selected paragraph or sentence.
- Observed behavior
- The text translation option is missing or unavailable within the application's built-in pop-up menu.
Ensure you have an active internet connection to process translations and install a third-party translation application (such as Google Translate) on your device, as your current PDF reader lacks native translation features.
Use Copy and Paste with a Translation App
Since Acrobat Reader Mobile lacks a built-in translation option, you can manually copy the text and paste it into a dedicated translator application.
While direct translation from the PDF pop-up menu is not supported in the Adobe Acrobat Reader app, you can easily bypass this limitation by relying on your device's clipboard.
This method works universally across both iOS and Android devices, provided you have a translation application installed.
Long-press on the text in your PDF document. Drag the selection handles to highlight the exact phrase or paragraph you want to translate.
Tap 'Copy' from the context menu that pops up right above your selected text.
Open a translation app like Google Translate or Apple Translate, tap the input field, select 'Paste', and choose your target language to view the translation.

Enable Tap to Translate (Android Only)
Android users can use Google Translate's overlay feature to translate copied text instantly without switching apps.
Translate PDF Text Directly Using WPS Office
Skip the hassle of switching between apps. WPS Office Mobile provides an integrated PDF reading and editing experience with built-in text translation, allowing you to select and translate document text instantly on your mobile device.
- 1. Open your PDF in WPS Office: Launch the WPS Office mobile app, tap on 'Files', and open the PDF document you need to read.
- 2. Highlight the text: Long-press the text you wish to translate to bring up the context menu, adjusting the cursors to select your specific sentence.
- 3. Tap Translate: Swipe through the options in the pop-up menu and tap the 'Translate' button to instantly display the translated text in your preferred language.

Frequently Asked Questions
Why is the translate option missing in Acrobat Reader Mobile?
Adobe Acrobat Reader Mobile does not currently feature a native text translation tool in its pop-up menu. Users must rely on copying the text and pasting it into an external translator app.
Are there mobile PDF readers that support built-in translation?
Yes, comprehensive office suites like WPS Office Mobile include built-in translation features for PDFs, allowing you to highlight text and translate it without leaving the document.
Can I translate an entire PDF document at once on my phone?
While you cannot translate an entire document directly inside most basic PDF readers, you can upload the PDF file to online services like Google Translate Documents via your mobile browser, or use advanced features in comprehensive office apps.
Does translating PDF text require an internet connection?
Most integrated translation tools and third-party apps require an internet connection. However, if you use an app like Google Translate and download offline language packs, you can translate copied text without Wi-Fi.
