Estimate how long a PDF will take to read or hear before converting it. This browser-only utility analyzes extractable text locally, compares reading time with narration at 1x, 1.5x, and 2x speed, and flags files that may need optical character recognition. It is a sizing and readiness check, not the converter itself. Long PDFs are estimated from evenly sampled pages, so results are planning estimates rather than guarantees.
The PDF stays in the browser during estimation and is not uploaded by this tool. To generate audio and unlock an offline file with Pro, open the PDF-to-audio and MP3 converter.
