Removing Text from images
Open the PDF file containing your image using Soda PDF.
When you remove image backgrounds in a PDF file, the first step is to get rid of any unnecessary text. You’ll use the OCR engine to scan the image and make the text editable and then delete it.
- Open the OCR tab.
Instead of scanning your entire document, you’ll use the OCR engine to scan only the image you are working with.
- Click into Edit Mode.
- Select your image.
- All images have a red border surrounding them.
- Choose Manual.
The video below will explain how to use the Manual OCR feature.
The OCR manual recognition window will open. You can configure what parts of your image you want to be scanned.
There will be a red border surrounding any text. When the OCR engine scans the document, it will make sure to make this text editable. You may see blue boxes around any sections deemed as an image. We recommend deleting any visible boxes except for what surrounds the text you want to remove.
- Choose Delete Block.
- Click on any section to remove it.
- Click Recognize to continue.
Now that the text has been recognized, you can easily remove it from the document. Each line of text will be in its own blue bordered text box.
- Select Edit Mode.
- Click on the text.
- While the cursor is in the text box, hold down the left mouse button and drag the cursor to select additional text.
- You can select the text in multiple text boxes at once.
Press the Delete key to remove the text.
