How PDF to text works
PDF to Text extracts the existing text layer from a PDF and saves it as a plain .txt file. The extraction is performed by pdf.js inside your browser, reading the text content objects embedded in the PDF's page streams. The document never leaves your device; the result is assembled locally and offered as a direct download.
This tool reads a text layer that is already present in the file. If your PDF was created by a word processor or export tool, it almost certainly has a text layer and extraction will work well. If the PDF is a scan of a paper document, the pages contain image data only and there is no text layer to extract; in that case, this tool will return empty or incomplete output. Scanned PDFs require optical character recognition (OCR) to produce text, which is a separate process not performed by this tool. Check whether your PDF has selectable text in a viewer before using this tool.
