Documents to PDF. Word (.docx), Excel (.xlsx, .csv), PowerPoint (.pptx), and plain text (.txt) files are converted to PDF via the browser print engine.

Web content to PDF. HTML files and raw HTML code are rendered and saved as PDF. URLs can also be captured as PDF.

Ebooks to PDF. EPUB files are converted to PDF with text content preserved.

PDF to other formats. Extract text from a PDF, convert pages to JPG images, export to HTML for web publishing, or extract content for Word editing.

OCR extraction. JPG, PNG, TIFF, and BMP images with text are processed through OCR to extract readable, editable text.

How the Smart Converter Works

Drop any file onto the converter. It reads the file extension and MIME type to identify the format. Then it automatically selects the correct conversion method and processes the file. You do not need to choose a conversion type manually — the tool handles that decision for you.

If you prefer to use a specific tool directly, the full list of individual tools is available on the PDF Tools page.
