PDF2MP3 is a browser-based PDF-to-audio service using neural text-to-speech to convert PDFs into MP3 files. Users upload PDF files (free trial limits apply), select language and one of dozens of voices, optionally adjust speed and pitch, and generate downloadable MP3 narration. The service extracts text locally in the browser and sends text to secure servers for synthesis, offers multi-language support, automatic metadata, batch processing for paid tiers, and prioritizes fast, studio-like natural voice output for accessibility and content reuse.
