Free AI Document Tools

Free AI document tools: convert documents and ebooks, compress PDFs, split or merge pages, and fill any PDF form.

Documents

• Document Converter
  Convert between DOCX, PDF, Markdown, HTML, plain text and RTF with a clean, layout-aware result. Runs entirely in your browser — your documents never leave this device.
• Ebook Converter
  Create and convert ebooks between EPUB, PDF, TXT, Markdown and HTML. Read EPUBs and re-package them on-device — your reading stays private.
• Compress PDF
  Reduce PDF file size while preserving quality. Preserve text & forms for a clean re-pack, or re-render as image for maximum compression. If a pass would not shrink the file, you get your original back — never worse.
• Split / Merge PDF
  Split a PDF by ranges or every N pages into a zip, or merge multiple PDFs into one. Page-exact copy — zero quality loss.
• Merge CSV Files
  Combine several CSV files into one — columns are matched up by header name, so files with columns in a different order (or a missing column) still merge cleanly. Runs entirely in your browser.
• Merge Excel Files
  Combine several Excel workbooks into one — as a single combined sheet with columns matched by header, or keep every sheet separate in one merged workbook. Runs entirely in your browser.
• Fill Forms Online
  Detect AcroForm fields in any PDF and fill text, checkboxes, radio buttons and dropdowns — or click straight onto a page to type. Then download a flattened, print-ready PDF.
