Yes. Upload any research paper to the Chat with PDF tool and ask: "Summarize this paper in 5 bullet points," "What is the main conclusion?" or "Explain the methodology in simple terms." PDFTash AI reads the entire document and answers based on the actual content. You can summarize 100-page papers in under 30 seconds.
Yes. The PDFTash Translate PDF tool converts entire PDF documents into 50+ languages while preserving the original layout, tables, figures and formatting. Upload a German chemistry paper, a Chinese economics journal, or a French historical document and get a translated PDF with the original structure intact. Essential for international research.
Go to PDFTash Compress PDF, upload your document, and it will compress automatically targeting the smallest possible size. For specific size targets (like 200KB for some portals), run a second pass on the compressed file. Text quality is never degraded — only image compression is applied, which is invisible to the human eye in most documents.

Yes. Upload your lecture notes or textbook chapter to Chat with PDF and ask: "Generate 10 multiple-choice practice questions based on this material" or "What are the most likely exam topics from this chapter?"
