The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices. The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator. Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request. **Pricing & Plans:** Freemium.

The interface is minimal — upload a PDF, choose a language and generate. The result is a concise overview that helps you decide whether a document is worth a full read or pulls out the essential points when you are short on time. Because it is free and open source, SmartPDFs is approachable for casual readers and developers alike. The summaries are produced by Llama 3.3 running on Together AI, a large language model that captures the main arguments, findings and conclusions of the source text. The language selector lets you generate the summary in a language you prefer, which is useful when working across documents written in other languages. SmartPDFs suits anyone who handles a lot of PDFs — students working through reading lists, professionals triaging reports and papers, or teams that want a fast, shareable overview of a long document. It works best with text-based PDFs; scanned documents without extractable text may not summarize reliably, and like any summarizer the output depends on the source content. **Pricing & Plans:** Free. SmartPDFs is free to use, with no paywall for generating PDF summaries. It is also open source. - **Instant PDF summaries:** Upload a PDF and get a concise summary in seconds, so you can understand the gist without reading the full document. - **Language selection:** Choose the language for the summary before generating, making it easy to read a document in your preferred language. - **Clear, shareable summaries:** Summaries are clean and easy to share with colleagues or classmates as a quick overview of a document. - **Open source:** SmartPDFs is open source, with its code published on GitHub for anyone to inspect or self-host. - **Powered by Llama 3.3 on Together AI:** Summaries are generated by Llama 3.3 running on Together AI, a modern large language model. **Strengths:** Completely free with no paywall; Very simple three-step flow: upload, choose language, generate; Open source and reviewable on GitHub; Language selection makes summaries readable across languages **Limitations:** Only handles PDF uploads, not other document formats; There is no stated account system or long-term document library; Summaries depend entirely on the quality of the source PDF text [Profile (Markdown)](https://openaitools.app/tool/smartpdfs.md) ## Frequently Asked Questions ### How do LightPDF and SmartPDFs compare in monthly traffic?
