Pro tips
- Best results come from text-based PDFs — scanned image PDFs need OCR first.
- Use 'Short' for quick takeaways, 'Detailed' when you need to brief someone else.
- For very long documents (50+ pages), only the first 50 pages are analyzed to keep results fast and accurate.
- Always review the AI summary before sharing — it's a starting point, not a substitute for the original.
Frequently asked questions
Is the PDF AI Summarizer free?
Yes — 100% free, no signup, no watermarks.
What kinds of PDFs work best?
Any text-based PDF: research papers, reports, contracts, manuals, books, articles, meeting notes. Scanned image PDFs won't work unless you OCR them first.
How long can the PDF be?
We analyze up to 50 pages per document. Longer PDFs are truncated to stay fast and accurate.
Is my PDF stored or shared?
No — text is extracted in your browser and sent securely for summarization. Nothing is permanently stored.
Can it summarize PDFs in other languages?
Yes — the summarizer handles documents in most major languages and returns the summary in the same language.
