An honest, complete document converter
Every common text format
Word (.docx), OpenDocument (.odt, LibreOffice), RTF, plain text, HTML page, Markdown and PDF, in both directions: 42 possible conversions.
Structure is kept
Headings, paragraphs, bold, italic, underline, bulleted and numbered lists, tables, links and images carry over from one format to another.
Faithful Word to PDF
A DOCX converted to PDF keeps its real layout: fonts, margins, tables, images, headers and footers, with selectable text.
Nothing leaves your device
Files are read and written inside your browser. No server, no account, no watermark, no trial limit.
Which document conversions can you do?
The converter reads seven formats: Word (.docx, plus .docm and .dotx), OpenDocument Text (.odt, the format of LibreOffice and OpenOffice), RTF, plain text (.txt), web page (.html), Markdown (.md) and PDFs that contain text. It writes the same seven formats. So you can convert DOCX to ODT for LibreOffice, ODT to Word, RTF to DOCX, a text file to PDF, an HTML page to Word, Markdown to DOCX or PDF, a Word document to Markdown for a website or wiki, or a PDF to editable text. Several files in different formats can be converted to the same format in one go.
What is kept, and what isn't
Every format has its limits, and the tool tells you before converting. Between Word, ODT, RTF, HTML and PDF, the text, headings, bold, italic, underline, superscript, lists, tables, links, images and page breaks are carried over. Fine layout, however, is simplified: exact fonts, colors, columns, text boxes, footnotes, headers and footers. The one exception: a Word file converted to PDF keeps its full layout, because it goes through the same engine as our Word to PDF tool. When converting to plain text, only the text remains. From a PDF, the text and its structure are rebuilt, but not the page layout or the images. If your document has a carefully designed layout, keep it in its original app for the final touches.
DOCX, ODT, RTF, Markdown: which format should you pick?
DOCX is the Microsoft Word format, the most widely used at work and at school: choose it to send a document others can edit. ODT is the open format of LibreOffice, free and standardized, and some public bodies ask for it. RTF is an old, very simple format that almost every word processor can open, even old ones. PDF is for sharing a document that must look the same everywhere. Markdown is text with a few symbols (# for a heading, ** for bold), used by developers, wikis and sites like GitHub or Notion. HTML gives you a web page to open in a browser, and TXT gives you bare text, ideal for copy-pasting or text-to-speech.
Turn a PDF into an editable document
A PDF isn't made to be edited: it describes letters placed on a page. To turn it into Word, ODT or text, the tool reads the text on each page, puts columns back into reading order, spots headings from the font size, rejoins words hyphenated at the end of a line, recovers lists and simple tables, and removes repeated headers and page numbers. You get a clean document to work on. If the PDF comes from a scanner or a photo, it only contains images: run it through our OCR PDF tool first to recognize the text. And to keep a PDF's original look as closely as possible in Word, the PDF to Word tool is a better fit.
Frequently Asked Questions
Are my documents uploaded to a server?
No. Files are read and converted by your browser, on your device. Nothing is sent to Chatzam or any other service, so it's fine for confidential documents too.
Can I convert an old .doc file?
Not directly: the old .doc format (Word 97 to 2003) is a closed binary format. Open it in Word, LibreOffice or Google Docs, save it as .docx, then drop that file here.
Why does the layout change a little?
Each format describes layout in its own way. The tool keeps the content and its structure (headings, lists, tables, images, links) and gives the result a clean, simple layout. Exact fonts, columns and text boxes aren't carried over, except for Word converted to PDF.
How do I convert a scanned PDF?
A scanned PDF only contains images of pages, with no text. Use Chatzam's OCR PDF tool first to recognize the text, then convert the resulting PDF here.
How is this different from the Word to PDF tool?
Word to PDF is specialized: it shows the pages before exporting and offers printing. This converter handles every conversion between seven formats, with several files at once; for DOCX to PDF, it uses the same layout engine.
How many documents can I convert at once?
Up to 20 files per batch, with no limit on the number of batches. Files of several tens of MB work on a computer; on a phone, available memory may limit very large documents.
