Imagine you wanted to convert an article or a printed agreement into editable text. You could spend hours retyping and then manually correcting it. Or you could convert all the contents into digital format using a scanner (or a digital camera) and Optical Character Recognition application – in just a couple of minutes!
Automatic OCR processing and PDF text recognition is now a necessity in many situations. With built-in Optical Character Recognition (OCR) technology, DocuFreezer lets you recognize text from various documents, thus becoming a useful OCR application. DocuFreezer is a reliable offline batch file converter for Windows 10 and older Windows systems.

The number of languages will be increased in further versions of DocuFreezer. If you would like to have more languages added, please contact our support team.
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.
OCR Conversion: Bitmapped PDF to Searchable PDF
You can also make your PDF searchable. DocuFreezer can create PDF containing editable text out of an image-only PDF or another filetype using the built-in OCR technology.
Text Recognition from AutoCAD DWG and DXF
DocuFreezer supports DWG and DXF drawings as input formats. Thus, you can get the text out of your CAD drawings in the form of searchable PDF or TXT. Simply add the files to the list, select PDF or TXT as Output file type, go to Settings and check option Make PDF searchable (OCR) or OCR (Optical Character Recognition).
How to OCR a PDF or image file – step-by-step instruction
- Open DocuFreezer
- Add files or an entire folder to the List of files
- Select Output file type: PDF or TEXT
- Go to Settings
- Place a check mark next to Make PDF searchable (OCR) or OCR (Optical Character Recognition)
- Select the language of your input documents (better not select many languages at the same time)
- Select Multipage and other options, if necessary
- Click Start
- 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.
