Convert PDF to Word, Excel, PowerPoint, JPG, PNG, and Text

Converting a PDF into an editable format has never been easier. Our online engine lets you extract document contents seamlessly:

  • PDF to Word (.docx): Convert document layouts to editable Microsoft Word files while preserving original typography.
  • PDF to Excel (.xlsx, .csv): Extract tables from your PDF pages and export them into structured worksheets or comma-separated tables.
  • PDF to PowerPoint (.pptx): Turn PDF slides back into Microsoft PowerPoint presentation decks.
  • PDF to Images (.jpg, .png): Render pages as high-resolution images or pack them into a structured ZIP file.
  • PDF to Text & HTML (.txt, .html): Strip formatting to obtain raw text data or convert pages into lightweight HTML code.

Convert Documents and Images to PDF

You can also convert standard file formats back into fully compliant, universal PDF documents. Simply upload files like Microsoft Word (`.doc`, `.docx`), Excel (`.xls`, `.xlsx`), PowerPoint (`.ppt`, `.pptx`), or digital photos (`.jpg`, `.jpeg`, `.png`, `.webp`, `.gif`), and our converter will process them instantly using premium layout rendering engines.

OCR for Scanned PDF Documents

If you have scanned paperwork, receipts, or image-only documents, check the OCR (Optical Character Recognition) option in the settings sidebar. Our advanced text recognition algorithms analyze the scanned image contents, extract characters, and produce searchable, selectable text in your final converted document, saving you hours of manual retyping.
