Method to Extract Text from Images Without Any Errors

Extracting text from images accurately—especially for languages like Czech with diacritics—can be challenging. But a method discussed and vetted by users has proven to deliver high precision and language compatibility.

:fire: Step-by-Step Guide for Flawless OCR Results:

1. Use Google Lens (Recommended on Mobile):
Google Lens supports Czech and handles accents better than most OCR engines. It works directly from your camera or gallery.

  • On Android: Built-in via the camera app or Google Photos.
  • On iOS: Use the Google app with Lens feature.

2. For Desktop Users – Convert Image to PDF, Then Use OCR:
If you’re working from a PC:

  • First, convert the image to a PDF (any photo editor or web tool works).
  • Open the PDF with Adobe Acrobat Reader or Google Drive and use their built-in OCR tools.

3. Online OCR Alternatives (with Language Selection):

  • OnlineOCR.net – Free, supports Czech. Upload → Select Language → Extract.
  • i2OCR – Specifically supports Czech and multi-column layouts.
  • NewOCR – Good accuracy with less compression loss.
  • Document AI by Google Cloud – Professional-level tool; requires setup but offers API.

4. Tesseract OCR with Czech Support (For Developers):
Install Tesseract OCR and use it with the Czech language pack:

tesseract input.jpg output.txt -l ces

Make sure tesseract-ocr-ces is installed (ces = Czech language).

:brain: Pro Tips for Accuracy:

  • Use high-resolution images (avoid screenshots of screenshots).
  • Prefer scans or sharp photos with good lighting and contrast.
  • Always crop out irrelevant areas to reduce OCR confusion.
  • If using scanned PDFs, ensure they’re not too compressed (which can degrade text clarity).

Bonus Tool:

  • Capture2Text – Lightweight OCR app for Windows with hotkey screenshot-to-text support. Czech included.

Conclusion:
For flawless results, Google Lens on mobile and Tesseract or NewOCR on desktop are the top picks. This method is especially powerful for Czech documents or textbooks, offering high accuracy even with special characters and diacritics.

Use this approach to digitize documents, translate text, or archive educational content—with near-zero errors.

Happy learning! :slight_smile:
