What PDF formats are supported?

Notevibes supports standard PDF files — text-based PDFs from any source including academic journals, business tools, ebook platforms, and document editors. The AI extracts text intelligently regardless of formatting or layout.

Is there a page limit for PDF uploads?

Free accounts can convert PDFs up to 10 pages. Paid plans support PDFs of any length — 100+ page reports, full textbooks, and lengthy research papers. There are no character limits on paid plans.

How does the AI handle tables and charts?

The AI detects tables and converts them into clear, spoken descriptions. For example, a data table becomes "Row 1: Revenue, $2.4 million. Row 2: Growth, 18 percent." Charts are described by their key data points and trends.

Can I convert scanned PDFs?

Yes, if the scanned PDF has an OCR text layer (most modern scans do). For image-only scans without a text layer, we recommend running OCR first using a free tool like Adobe Acrobat or Google Drive, then uploading the result.

What happens to headers, footers, and page numbers?

The AI intelligently strips page numbers, headers, footers, and other formatting artifacts. It focuses on the actual content — paragraphs, sections, and meaningful text — so the audio flows naturally.

Can I convert PDFs in languages other than English?

Yes. Notevibes supports 40+ languages. Upload a PDF in any supported language and the AI will extract and narrate the text with native-quality pronunciation and natural delivery.

What audio formats can I download?

Download as MP3, WAV, OGG, or ULAW. MP3 is ideal for listening on phones and portable devices. WAV provides lossless quality for professional use.

Is this PDF to audio tool free?

Notevibes offers a free tier to get started. Test all document presets, 45+ style modifiers, and custom prompts. Upgrade to a paid plan for longer PDFs and full-length document conversion.

How natural does the AI narration sound?

Notevibes AI voices deliver clear, human-like speech with natural pauses, breathing, and expression. Document presets are tuned for informational content — measured pacing, clear diction, and professional delivery that makes dense documents easy to follow.
