Use Adobe Acrobat to Scan and Convert Images to PDF
Utilize Adobe Acrobat's built-in creation tools to scan directly from a connected scanner, or convert existing image files into a searchable PDF document.
Adobe Acrobat provides direct integration with most desktop scanners, allowing you to capture pages straight into a PDF file. It also offers a dedicated tool to quickly convert existing JPEG images into PDFs and make the text searchable using Optical Character Recognition (OCR).
Launch Adobe Acrobat. Go to the Tools menu and select the 'Create PDF' option from the available tools list.
Click on 'Scanner' to capture a physical document. Select your connected scanner from the dropdown menu, adjust settings like color mode and resolution, and click 'Scan'. Arrange your scanned pages in the desired order.
If you already have digital photos or scans, choose the JPEG-to-PDF conversion option or select 'Single File' / 'Multiple Files', then browse your computer to import your JPEG files.
To make the text selectable and searchable, navigate to the 'Scan & OCR' tool. Click 'Recognize Text' and select 'In This File' to process the scanned images.
Once the scanning or conversion is complete, click 'File' > 'Save As' and choose a destination on your computer to save your new PDF.

Frequently Asked Questions
Why is the OCR not recognizing the text in my scanned PDF?
OCR technology may struggle with low-resolution scans, handwritten notes, or poor lighting. Ensure your original scan is set to at least 300 DPI and that the text is clearly legible without heavy shadows or blur.
Can I convert multiple JPEG images into a single PDF?
Yes. Most modern PDF editors, including Adobe Acrobat and WPS Office, allow you to select multiple image files at once and merge them into a single, continuous PDF document during the conversion process.
Is it possible to scan directly from my mobile phone instead of a flatbed scanner?
Absolutely. You can use mobile scanning applications like the WPS Office mobile app to take photos of paper documents. The app automatically crops, enhances, and converts these images into standardized PDF files.
