Document converter
Office documents are the one category where faithfully preserving a layout genuinely needs a full office engine — fonts, tables, styles, footnotes and page breaks all interact, and an approximation is obvious the moment somebody opens it. So these conversions are done properly, and this is the part of the site where that means our server rather than your browser.
Up to 100 files at once. Mixed formats are fine.
They convert one after another and download together as a ZIP.
Most used document conversions
Every document format we handle
21 formats in this category, 57 working conversions — 22 of them without your file leaving the device.
- XLSXXLSX
The Excel format since 2007. Several sheets, formulas, formatting.
- TXTTXT
Characters and nothing else. Will still open in fifty years.
Convert to PDF
- ODTODT
The open text document standard, written by LibreOffice and OpenOffice.
- DOCXDOCX
The Word format since 2007. A ZIP archive full of XML, which is why it converts reasonably well.
- RTFRTF
Formatted text every word processor can open. The lowest common denominator with styling.
- ODSODS
The open spreadsheet standard. Formulas, several sheets, no vendor lock-in.
- ODPODP
The open presentation standard, the LibreOffice Impress counterpart to PPTX.
- DOCDOC
The old binary Word format. Still turns up in archives and government downloads.
- PPTXPPTX

- PPTPPT
The old binary PowerPoint format.

Convert to PDF
- DOCMDOCM
A Word document carrying macros. Converting it to PDF is often the point — the macros do not come along.

Convert to PDF
- XLSMXLSM
An Excel workbook with macros attached.
Convert to PDF
- PPSPPS

Tools for document files
A student against a word limit, a writer checking a brief, or somebody trimming a post to fit a character count — and, far less often served, anybody who needs the word count of a file rather than of text they can paste.
Why these do not run in your browser
Almost everything else here runs on your own machine, and it is worth being straight about why documents do not. Rendering a Word file the way Word renders it means running the same engine, and that engine is a large desktop application rather than something that fits in a browser tab. The alternative would be a converter that produces a document which is nearly right, which for anything you are sending to another person is not much better than nothing.
What happens instead: the file is processed and its working directory deleted as soon as the result has been read. There is no history, no account and no bucket to look in. Every page states which kind of conversion it is before you start, so you always know which of the two you are choosing.
What survives and what does not
Text, styles, tables, images, headers and page structure come across. Where the target format has no equivalent for something — a Word feature that OpenDocument lacks, or the reverse — it is approximated rather than dropped silently, which is the same thing the desktop applications do when they open each other’s files.
Converting to PDF is the one direction where nothing is lost, because a PDF is a description of a finished page rather than an editable document. That is also its limitation: a PDF is what you send when you want it to look identical everywhere, and not what you send when you want it edited.
Document converter: common questions
Are these documents uploaded?
Yes, and this category is the exception on this site rather than the rule. Faithful office conversion needs an engine no browser can host. The file is processed and deleted immediately — nothing is stored, and every page says which kind of conversion it is before you start.
Will my layout survive?
It is rendered by the same engine a desktop office suite uses, so tables, styles, images and page breaks come across. Where a feature has no equivalent in the target format it is approximated, exactly as the desktop applications do when they open each other’s files.
Can I convert a PDF back into an editable Word file?
A PDF describes a finished page rather than a document structure, so anything reconstructing it is guessing at where paragraphs and tables were. We extract the text faithfully; we do not pretend to rebuild the original layout.
Is there a cost or an account?
Neither. There is no sign-up, no watermark and no paid tier, and no daily cap on how many documents you convert. The office conversions are the part of this site that costs us server time, and they are still free.
