Convert PNG to TXT — Free Online Converter

Converting PNG to TXT is functionally identical to PNG to TEXT — both extract readable text from your image using Optical Character Recognition (OCR) and save it as a plain text file with the .txt extension. The process analyzes the PNG's pixel data to identify characters and outputs machine-readable text that can be searched, edited, copied, and processed programmatically.

The .txt extension is the most universally compatible text format — every operating system, text editor, programming language, and database can read .txt files. The extracted text uses UTF-8 encoding, supporting characters from virtually every written language. This makes PNG to TXT ideal for digitizing printed documents, extracting data from screenshot tables, and making image-based text accessible.

Digitizing printed content is the primary use case. Scanned documents, printed receipts, photographed labels, and screenshot text all exist as pixels that cannot be searched, edited, or processed. Extracting the text to .txt makes the content available for full-text search, database entry, spreadsheet import, and programmatic analysis.

Compliance and accessibility regulations often require text versions of image content. WCAG accessibility guidelines mandate that text information be available in machine-readable form. Section 508 compliance for U.S. government systems requires the same. Converting PNG documents to TXT satisfies these requirements and makes the content available to screen readers and assistive technologies.

Tesseract OCR engine analyzes the PNG image using LSTM neural networks for character recognition. Pre-processing includes automatic page layout analysis, text region detection, line segmentation, and binarization. The engine supports 17 languages with dedicated trained models. Output is plain UTF-8 text with line breaks preserving the original text flow. PNG's lossless compression gives Tesseract cleaner input than JPEG sources, measurably improving recognition accuracy.
