What Can You Do with These PDF Tools?
This collection covers the most common PDF workflows that people search for: converting office documents to PDF, reducing PDF file sizes for email, and making PDF content accessible through audio playback.
Every tool runs entirely in your browser. There is no server-side processing, no file upload, and no account required. This means your confidential documents, financial reports, and personal files stay on your device throughout the entire conversion process.
The conversion tools support the most widely used input formats: Word documents (DOCX), Excel spreadsheets (XLSX, XLS, CSV), ebook files (EPUB), and images (PNG). Each converter parses the source file locally and renders a preview before you export the final PDF through the browser print dialog.
The optimization and audio tools extend beyond simple conversion. The PDF Optimizer helps you understand why a PDF is large and what steps to take to reduce its size. The speech tools make PDF content accessible to people who prefer listening or need hands-free document review.
