Remove Unwanted Invisible Text in PDF Documents for Accurate Extraction

When dealing with PDF documents, sometimes there may be unwanted invisible text that makes it difficult to extract the desired content accurately. This could be due to various reasons such as the original document being scanned or saved with a low-quality setting. In such cases, it is important to remove the unwanted invisible text to ensure accurate extraction of the desired content.

To remove the invisible text from the PDF, Try using any of these profiles below:

{
    "profiles": "{\n  \"ExtractInvisibleText\": false,\n  \"ExtractShadowLikeText\": false,\n  \"OCRMode\": \"Auto\"\n}"
}

{
    "profiles": "{\n  \"ExtractInvisibleText\": false,\n  \"ExtractShadowLikeText\": false,\n  \"ColumnDetectionMode\": \"ContentGroups\",\n  \"OCRMode\": \"Auto\",\n  \"CSVSeparatorSymbol\": \",\"\n}"
}

{
    "profiles": "{\n  \"ExtractInvisibleText\": false,\n  \"ExtractShadowLikeText\": false,\n  \"LineGroupingMode\": \"GroupByRows\",\n  \"ColumnDetectionMode\": \"ContentGroups\",\n  \"OCRMode\": \"Auto\",\n  \"CSVSeparatorSymbol\": \",\"\n}"
}

In addition, you can also use the ByteScout PDF Multitool to experiment with different extraction profiles to find the perfect one for your PDF document.
