If the text in your PDF isn't editable, that might be because the document only contains pictures of text, rather than the original text data itself. This is often the case with scanned documents. In order to make a scanned document editable, the images need to be converted back into text. PicoPDF uses Optical Character Recognition (OCR) to convert images into editable text.

Use the OCR tool to convert images into editable text. You can access the OCR tool from the Home Tab or from the Tools Menu. The OCR tool will search the document for images containing text, then replaces each image with text that can be edited.

Please note that the accuracy of converting images to text is highly dependent on the sharpness of the image and clarity of the texts in the image.
