Convert Scanned Image to Text – from TIFF, JPEG, PNG

When you scan a document, it becomes an image. Afterward, you might need to get the text out of it. The text that you can edit with a word processing, spreadsheet, or an editing program. Use an OCR converter for this task – just add images and let the software OCR your files. Once the OCR is done, text in searchable PDF documents can be selected, copied, and marked up.

How to OCR a PDF or image file – step-by-step instruction

  1. Open DocuFreezer
  2. Add files or an entire folder to the List of files
  3. Select Output file type: PDF or TEXT
  4. Go to Settings
  5. Place a check mark next to Make PDF searchable (OCR) or OCR (Optical Character Recognition)
  6. Select the language of your input documents (better not select many languages at the same time)
  7. Select Multipage and other options, if necessary
  8. Click Start
  9. Get the resulting files in the Output folder

How to ensure the best results:

  • Images (especially screenshots) must be scaled up so that the text height is at least 20 pixels
  • Select only those languages that are contained in your documents
  • The text of the original file must not have any rotation or skew
  • Dark borders must be manually removed, or they will be misinterpreted as characters

Please note, that text may be incorrect or corrupted after conversion with OCR. Make sure that the input files have high quality – large format and high resolution.

What is Optical Character Recognition

Optical character recognition (OCR) is a method of converting a scanned image into text. When a page is scanned, it is usually stored as a bitmapped JPEG or TIFF format. When the image is on the screen, we can read it. But to the computer, it is just a series of black and white dots. The computer does not recognize any “words” or actual characters on the image. DocuFreezer can help you turn a flat image into letters and characters. Try the OCR feature in the free version of DocuFreezer – download the program using the button below.
