Question details
The user wants to locate a PDF file on their mobile device, upload it to a cloud service, and prepare it for Optical Character Recognition (OCR) to extract or edit the text.
- Product
- Mobile PDF App
- Device & OS
- iOS, Android
- Scenario
- Accessing local mobile files and converting scanned PDFs or images to editable text via a mobile application.
- Observed behavior
- Needs a clear, step-by-step method to locate local documents on a smartphone, upload them securely, and process them with an OCR engine.
Ensure your mobile device is connected to a stable internet network, as uploading files to the cloud and running OCR processing often requires online access. Gather the PDF files you intend to process into an easily accessible folder on your device.
Use the Adobe Acrobat Reader Mobile App
Upload and process PDFs using the Adobe Acrobat Reader app for iOS or Android, which integrates with Adobe Document Cloud.
Adobe Acrobat Reader provides a seamless way to locate local files and upload them to the cloud for advanced processing. Keep in mind that full OCR capabilities might require a premium Adobe subscription.
Download the free Adobe Acrobat Reader mobile app from the App Store or Google Play, launch the application, and sign in to your Adobe account.
Tap the 'Files' tab at the bottom menu and select 'On This Device' to browse your local mobile storage for the PDF file.
Select the file and choose to upload or save it to Adobe Document Cloud for secure storage and cross-device access.
Use the 'Export PDF' or 'Scan' feature within the app to apply Optical Character Recognition (OCR) and convert the scanned document into editable text.
Use Native Cloud Drives (Google Drive / iCloud)
Upload your PDF to standard cloud drives like Google Drive to utilize their built-in text recognition.
Perform Mobile PDF Uploads and OCR with WPS Office
WPS Office provides a powerful, all-in-one mobile app that lets you easily locate local PDFs, sync them to WPS Cloud, and perform high-accuracy OCR to extract text directly from your phone.

- 2. Upload to WPS Cloud: Select your PDF file and tap 'Upload to Cloud' (or turn on auto-sync) to back it up and make it accessible across all your devices.
- 3. Select the OCR Tool: Open the PDF document, tap the 'Tools' menu icon at the bottom of the screen, and select 'OCR' or 'Picture to Text'.
- 4. Extract and Edit Text: Choose the pages or sections you want to process. WPS will automatically extract the text, allowing you to copy it or export it directly as a new Word document.
Frequently Asked Questions
Can I perform OCR on a PDF without an internet connection?
Most advanced OCR tools on mobile apps require an internet connection because the complex text-recognition algorithms run on cloud servers. However, basic offline text extraction might be supported by specific localized apps.
Why does the OCR output have so many spelling mistakes?
OCR accuracy depends heavily on the visual quality of the original PDF. Blurry text, low-resolution scans, handwritten notes, or complex multi-column layouts can confuse the engine. Enhancing the scan quality before running OCR will drastically improve the results.
Where are downloaded PDF files typically stored on my phone?
On Android devices, PDFs downloaded from the browser are usually found in the 'Downloads' folder within the 'My Files' app. On iPhones, they are typically saved to the 'Downloads' folder inside the native 'Files' app, either on your local drive or iCloud Drive.
Is it possible to convert the OCR text back into a Microsoft Word format?
Yes. Comprehensive PDF editors, including WPS Office, allow you to run OCR on a scanned PDF and export the recognized text directly into a fully formatted, compatible .docx file for straightforward editing.
