PDF TO MP3 — Turn PDFs into audiobooks with the AI you already pay for

PDF TO MP3 turns PDF documents into audiobooks. It can be used two ways: connect your existing Codex or Claude subscription via an MCP server to handle document processing (so PDF TO MP3 itself costs $0, with speech generation billed directly by OpenAI or Google), or use fully hosted plans where PDF TO MP3 handles processing and billing. Documents can be listened to on the web, in iPhone/Android apps, or downloaded as MP3s.

Key Features

Use your existing AI subscription

Connect Codex or Claude by adding the PDF TO MP3 MCP server, so document processing runs through the AI subscription you already pay for at no extra cost from PDF TO MP3.

Bring your own speech key

Add an OpenAI or Gemini API key that pays for speech generation directly, billed per usage by OpenAI or Google rather than by PDF TO MP3.

Hosted all-in-one plans

Alternatively, upload documents and let PDF TO MP3 handle all processing and usage billing, with credits covering processing, audio creation, questions, and live conversations.

Ask and Explain

Ask live questions about your documents and use the Ask and Explain buttons; credits are consumed for questions and live conversations.

Automatic translation

Upload a document in one language and generate the audio in another to hear a translation.

MP3 download and mobile apps

Download a full MP3 for the whole document or per-chapter MP3s, and listen on the web or in the iPhone and Android apps.

Premium TTS and multi-speaker

Paid plans include premium text-to-speech and multi-speaker audio creation.

How It Works

01. Connect your AI

Sign in, choose Codex or Claude, and in Codex open Settings → Plugins → Add MCP server with Streamable HTTP, paste the provided server address, then authenticate to connect your PDF TO MP3 account.

02. Add your speech key

Choose OpenAI or Gemini to make your speech and add the corresponding API key, which pays for speech generation only. Enable billing in the Gemini console for improved reliability.

03. Send your first document

Attach a PDF in your AI chat and ask it to use the PDF TO MP3 MCP to turn the document into an audiobook. Your subscription covers document processing via MCP, and your API key covers speech generation.
