FAQ
Frequently Asked Questions
Common questions about using text to speech with PDF documents
How do I convert a PDF to speech?
+
Upload your PDF, choose one of 75 AI voices, and start the conversion. You can preview any voice first, fine-tune speed and pitch, and download the result as MP3. Everything runs in your browser, with nothing to install. The tool extracts text from your PDF locally using PDF.js, so your original file never leaves your device. Once you pick a voice and confirm settings, the synthesized audio is generated server-side and delivered as a downloadable MP3. Typical turnaround is under a minute for a 10-page document. You can also switch languages mid-session if your PDF contains multilingual content, selecting a different voice for each conversion.
Can I turn a PDF into voice for free?
+
Yes. PDF2MP3 is free to try: upload a PDF, preview voices, and convert it to audio right in your browser. Your first conversion covers up to 1,000 characters with a standard voice, no credit card required. Voice previews remain free regardless of your plan, so you can always test how a document sounds before spending anything. Longer documents and premium HD voices consume credits, which you can purchase as a one-time pack or through a monthly subscription. The converter displays the exact credit cost before you confirm, so there are no surprises. Most short articles and memos fall well within the free allowance for a quick test.
How is this different from a screen reader?
+
Built-in screen readers use robotic system voices and require your screen to stay on. Our AI voices sound natural and human-like, and you can download the audio as MP3 to listen offline on any device. Screen readers also struggle with complex PDF layouts: multi-column text, sidebars, and footnotes often get jumbled into incoherent sequences. PDF2MP3 uses intelligent text extraction that preserves the intended reading order. Additionally, screen readers typically offer one or two system voices with limited speed control, while this tool gives you 75 voices across 8 languages with fine-grained speed and pitch adjustment for a comfortable listening experience.
Can I preview voices before converting?
+
Yes. Upload your PDF and preview any voice with a short sample of your actual text. Compare voices, speeds, and pitches before converting the full document. Previews generate in 2 to 5 seconds and use your real content rather than a generic demo clip, so you hear exactly how the narration will sound. This is especially useful when choosing between regional accents (American vs. British English, for example) or when tuning speed for dense technical material versus light reading. Previews are always free and do not consume credits, so you can test as many combinations as you like before committing to a full conversion.
What languages are supported?
+
We currently support 8 languages with 75 distinct voice options: American English (27), British English (8), Japanese (5), French (7), German (7), Spanish (10), Chinese (8), and Portuguese (3). Each language uses region-appropriate pronunciation models rather than a single generic engine, so French voices sound natively French, not English with a French filter. Language learners often use the tool to listen to documents in their target language while following the PDF text visually, strengthening both listening comprehension and reading speed at once. For long-form content such as novels or full textbooks, you can also create complete audiobooks from your PDFs.
How long does conversion take?
+
Preview generation takes 2 to 5 seconds. Full conversion runs at roughly 10 pages in 30 to 60 seconds, scaling to about 3 to 5 minutes for a 100-page document. Speed depends on document complexity and current server load, but most users find conversions finish faster than they expected. Text-dense academic papers may take slightly longer per page than lightly formatted articles. Pro subscribers get priority queue processing, which noticeably reduces wait times during peak hours. You can close the browser tab while conversion runs in the background and return later to download the finished MP3 whenever it is ready.
What's the maximum file size?
+
We support PDFs up to 50MB, which accommodates roughly 150 pages. This covers most articles, textbooks, research papers, and business documents. The limit applies to the PDF file size rather than the extracted text length, so image-heavy PDFs with less text will convert faster than text-dense ones of the same file size. If your document exceeds 50MB, splitting it into chapters or sections before uploading is a practical workaround. Each segment converts independently and produces its own MP3. You can then play the files sequentially in any audio player or merge them later with a free tool like Audacity or FFmpeg.
Is my PDF stored on your servers?
+
No. Text extraction happens in your browser using PDF.js, so your PDF file never leaves your device. Only the extracted plain text is sent to the server for voice synthesis, and that text is discarded immediately after the audio is generated. We maintain a strict zero file storage policy: no PDFs, no extracted text, and no converted audio files are retained on our infrastructure after processing. This architecture means even if our servers were compromised, your original documents would not be exposed. It is a deliberate design choice for users who handle sensitive business contracts, legal filings, medical records, or unpublished academic research.
Can I use this for language learning?
+
Absolutely. Choose a voice in your target language, slow the speed to 0.5x, and follow along with the PDF text on screen. It is an effective way to improve listening comprehension and pronunciation simultaneously. Studies on dual-coding theory (Paivio, 1986) suggest that combining reading with listening can strengthen recall, particularly for complex or unfamiliar material. You can convert textbook chapters, news articles, or graded readers into audio and practice during commutes or at the gym. Repeating the same section at progressively faster speeds helps train your ear for natural speech rhythm before moving to full-speed native content, building confidence incrementally.
What audio format is produced?
+
All conversions produce standard MP3 files at 128kbps, a bit rate that balances speech audio clarity with compact file size. At this rate, one minute of speech is roughly 1MB, so a 45-minute document weighs about 45MB and fits easily on any modern device. The MP3 format is universally compatible: smartphones, tablets, computers, car audio systems, smart speakers, and dedicated MP3 players all handle it natively without any special app or codec. If you need another format afterward, standard audio tools such as Audacity, VLC, or FFmpeg can re-encode the file in seconds. Convert your PDF to audio now →
Does it work with scanned PDFs?
+
Our TTS works best with text-based PDFs where the text layer is embedded in the file. Scanned documents (image-based) need OCR processing first to extract readable text before conversion is possible. You can check whether your PDF has a text layer by trying to select and highlight words in a regular PDF viewer: if selection works, the file is compatible. If not, run it through an OCR tool such as Adobe Acrobat, ABBYY FineReader, or the free open-source Tesseract engine to add a text layer, then upload the result. Most modern scanners and phone scanning apps like Apple Notes or Adobe Scan produce OCR-ready PDFs by default.
Can I adjust how the voice sounds?
+
Yes. Control playback speed (0.5x to 2x) and pitch to customize the listening experience. Slower speeds are great for language learning, faster speeds for quick document reviews. These settings are applied during synthesis, so the downloaded MP3 already contains your chosen speed and pitch baked in. For example, setting 1.5x speed on a 60-minute document produces a roughly 40-minute MP3 with no chipmunk effect, since the AI model regenerates the speech at the target rate rather than simply time-compressing the waveform. You can preview different speed and pitch combinations before committing to a full conversion to find what sounds best.
