Powerful OCR for Python Applications

Our library integrates easily, enabling Python applications to run seamlessly on any platform – desktop Windows, Windows Server, macOS, Linux, and the cloud.

130+ Recognition Languages

Our Python and .NET OCR API recognizes a plethora of languages and popular writing scripts, including mixed languages:

Leave language detection to the library or define the language yourself for enhanced recognition performance and reliability.

  • Extended Latin alphabet: English, Spanish, French, Indonesian, Portuguese, German, Vietnamese, Turkish, Italian, Polish, and 80+ more;
  • Cyrillic alphabet: Russian, Ukrainian, Kazakh, Serbian, Belarusan, Bulgarian;
  • Arabic, Persian, Urdu;
  • Chinese and Devanagari script, including Hindi, Marathi, Bhojpuri, and others.

Powerful processing filters

The accuracy and reliability of optical character recognition is highly dependent on the quality of the original image. Aspose.OCR for Python via .NET offers a large number of fully automated and manual image processing filters that enhance an image before it is sent to the OCR engine:

  • Automatically straighten images aligned at a slight angle to the horizontal.
  • Manually rotate severely skewed images.
  • Automatically remove dirt, spots, scratches, glare, unwanted gradients, and other noise.
  • Automatically adjust the image contrast.
  • Automatically upscale, or manually resize the image.
  • Convert images to black and white or grayscale.
  • Invert image colors so that light areas appear dark and dark areas appear light.
  • Increase the thickness of characters in an image.
  • Blur noisy images while preserving the edges of letters.
  • Straighten page curvature and fix camera lens distortion for page photos.

Optimized for specific document types

Aspose.OCR for Python via .NET offers specially trained neural networks to extract text from certain types of images with maximum accuracy:

Built-in spell checker

Although Aspose.OCR for Python via .NET provides high recognition accuracy, printing defects, dirt, or non-standard fonts may cause certain characters or words to be recognized incorrectly. To further improve recognition results, you can turn on spell checker, which finds and automatically corrects spelling errors based on the selected recognition language.

If the recognized text contains specialized terminology, abbreviations, and other words which are not present in common spelling dictionaries, you can provide your own word lists.

Batch Recognition Simplified

Our Python OCR API liberates you from recognizing images one by one. Employ various batch-processing methods to recognize multiple images in one call:

  • Recognition of multi-page PDF, TIFF, and DjVu files.
  • Recognition of all files in a folder.
  • Recognition of all files in an archive.
  • Recognition of all files from a list.

Recognize text on Photos

Reading text from any content in Aspose.OCR for Python via .NET is as easy as calling a universal recognize() method.

Convert photo to text - Python

api = AsposeOcr()
# Add image to the recognition batch
input = OcrInput(InputType.SINGLE_IMAGE)

# Set recognition language
recognitionSettings = RecognitionSettings()
recognitionSettings.language = Language.UKR;

# Recognize the image
results = api.recognize(input, recognitionSettings)

# Print recognition result
for result in results:

Python Universal Converter

Our API adeptly reads any image from scanners, cameras, or smartphones: PDF documents, JPEG, PNG, TIFF, GIF, BMP images, and even DjVu files. Full support for multi-page PDF documents, TIFF, and DjVu images ensures versatility. You can also provide an image from the web via a URL.

Recognition results are returned in popular document and data exchange formats: plain text, PDF, Microsoft Word, Microsoft Excel, JSON, and XML.

Recognize PDF and Save Results to various output formats - Python

api = AsposeOcr()

# Create OcrInput and add images
input = OcrInput(aspose.ocr.models.InputType.PDF)
file = os.path.join(self.dataDir, "pdfs/multi_page_1.pdf")
input.add(file, 0, 3)

set = RecognitionSettings()
set.set_detect_areas_mode = DetectAreasMode.NONE
result = api.recognize(input, set)
api.save_multipage_document("test.xml", SaveFormat.XML, result)
api.save_multipage_document("test.json", SaveFormat.JSON, result)
api.save_multipage_document("test.pdf", SaveFormat.PDF, result)
api.save_multipage_document("test.xlsx", SaveFormat.XLSX, result)
api.save_multipage_document("test.docx", SaveFormat.DOCX, result)
api.save_multipage_document("test.txt", SaveFormat.TEXT, result)
api.save_multipage_document("test.html", SaveFormat.HTML, result)
api.save_multipage_document("test.epub", SaveFormat.EPUB, result)
api.save_multipage_document("test.rtf", SaveFormat.RTF, result)

Resource Optimization in Python

Optical character recognition demands resources. Our API offers flexible ways to balance the classic time-price-quality triad:

  • Choose between thorough recognition and fast recognition.
  • Specify the number of threads allocated for recognition, or allow the library to automatically scale to the number of processor cores.
  • Free up the CPU by offloading calculations to the .NET backend.

Fast Recognition - Python

api = AsposeOcr()

# Create OcrInput and add images
input = OcrInput(InputType.SINGLE_IMAGE)

result = api.recognize_fast(input)

Recognize single line

If your image is already trimmed to a single line of text, it can be recognized in the fastest possible mode, without automated corrections, content structure detection, and other resource-consuming steps. It can speed up OCR up to 7 times faster than normal recognition process.

Recognize single line of text on image - Python

api = AsposeOcr()

# Create OcrInput and add images
input = OcrInput(InputType.SINGLE_IMAGE)

# recognize without regions detection
settings = RecognitionSettings()
settings.recognize_single_line = True

result = api.recognize(input, settings)
