TXT to MP3

Convert TXT Files to MP3 Audiobooks

Turn a plain text file you have the rights to into a natural-sounding MP3 audiobook — choose Standard or Premium, preview for free, and pay only for your file.

Most text-to-speech tools stop at a few thousand characters — enough for a paragraph, useless for a book. HirayaAI converts entire TXT files: a full manuscript, a long story, compiled notes or a public domain classic, narrated end to end with natural AI voices and delivered as one MP3 audiobook with proper pacing and ID3 tags. Premium also includes a chaptered M4B for compatible audiobook players.

TXT is the simplest format to convert — no layout to fight, just your words. Upload the file, choose Standard or Premium narration, and hear a free preview from your actual text. See the exact price, then pay once to convert the whole file.

Good to know

What makes TXT conversion different

Bring the whole file. Upload a manuscript, story, or collection of notes. Choose Standard or Premium narration; we check the file and show its exact price during preview. Pay once for the complete audiobook, with no subscription.

Structure is detected from your text. Chapter-style headings (like "Chapter 1") become narrated sections with natural pauses. Text without headings is split into evenly sized sections automatically, so long listens stay comfortable either way.

FAQ

TXT conversion questions

Is there a character or word limit for TXT files?

HirayaAI supports full-length books as well as shorter documents. Limits depend on your voice option; your file is checked during preview before payment. Standard is $2.99 per file up to 20,000 words, $6 up to 150,000 words, or $10 for longer files. Premium pricing is calculated from your file during preview. You see the exact price before paying. Applicable taxes are added at checkout. No subscription.

How is this different from a free text-to-speech reader?

Free TTS readers speak a snippet aloud in your browser. HirayaAI produces a downloadable MP3 audiobook of the entire file — chapter detection, natural pacing, one continuous file with ID3 tags — that you keep and play on any device, online or offline.

Can I convert pasted or exported text, like notes or a manuscript?

Yes. Anything saved as a .txt file converts: manuscripts, compiled notes, long-form writing or public domain books, as long as you own the content or have the rights to use it.

What audio format do I get?

Both options include a complete MP3 audiobook. Premium also includes a chaptered M4B for compatible audiobook players. Your download link stays active for 7 days and is also emailed to you.
