PDF to MP3, convert any document into audio you keep
Upload a PDF. Get a downloadable MP3 in minutes. No subscription, no app to install, no streaming-only catch, the file is yours and works in every audio player you already use.
Most "PDF to MP3" tools fall into one of two traps. They're free but they sound like a 2003 satnav. Or the voices are good but you can only listen inside the tool's app, no download, no AirPods on a plane, no CarPlay. Harkable was built to skip both. We use the same tier of neural voices that creators pay subscriptions for, and the output is a standard MP3 you download and own forever.
The flow is intentionally boring: drop the PDF in, pick a voice, pick a quality, click generate. A few minutes later there's an MP3 on your machine. Put it on your phone, drop it into a podcast app, send it to a Kindle, whatever, once the file exists, Harkable is out of the way.
The flow, end to end
1. Upload your PDF
Drag and drop the file at /convert. PDFs, Word docs, and pasted text all work. We extract the text and strip the citation noise, page headers, footnote markers, URLs, and bibliography sections, so the narration flows.
2. Pick voice + quality
Choose from a curated set of OpenAI neural voices and preview each one before you commit. Quality modes let you trade off speed and cost for the highest-fidelity rendering when it matters.
3. Generate the MP3
Click generate. A long PDF takes a few minutes. The file then waits in your library for 7 days, recoverable on any device, no email pings, just open the tab when you're ready.
4. Download and listen anywhere
The MP3 lives on your device, not behind a login. Apple Music, Spotify offline imports, Pocket Casts, CarPlay, AirPods, your dumb gym headphones, if it plays MP3s, it plays Harkable.
Voice quality and modes
Harkable runs on OpenAI's 2026-generation TTS, the same voice tier creators use to narrate audiobooks for sale. There are multiple voices to choose from, each with a real sense of pace and breath. They handle long-form reading without the flat, mechanical drift that gives most TTS away in the first paragraph.
For most documents the default quality mode is what you want. For a paper or chapter you'll listen to repeatedly, the higher quality mode is worth the small extra cost, pronunciation, phrasing, and prosody all improve noticeably.
Pricing, briefly
Two MP3s every month are free, forever. No card required to start. Beyond that, credits start at $5 and never expire. A typical 20-page paper costs around $0.50–$1.00. A 200-page book is around $20, once.
There's no subscription. You don't have to remember to cancel. If you only convert a couple of documents a year, you'll spend nothing most months. If you batch through a stack during midterms or a big project, you pay for that stretch and stop.
