In the digital age, PDFs are among the most commonly used file formats for documents. Whether you’re handling reports, scanned letters, academic papers, or forms, there often comes a time when you need to extract or transcribe text from a PDF file. Depending on the type of PDF—whether it’s text-based or a scanned image—the tools you’ll need can vary.
In this article, we’ll explore the best AI and OCR (Optical Character Recognition) tools that can help you transcribe text from PDFs efficiently. We’ll also compare their features, highlight free options, and guide you toward the right solution for your specific needs.
📂 Types of PDF Files: Know Before You Start
