1Upload the Word documents you want to work on; the file opens on an editable canvas in your browser with nothing installed.
2Crop, rotate, resize, draw, add text and shapes, or adjust colour — every change lands on a working copy, never on your upload.

4Export back to Word, or to a lossless format instead if you are still part-way through editing.
Word Editor FAQ
Is my file uploaded, or does editing happen locally?
+
Editing happens in your browser; the file goes to our workers only for the operations that genuinely need server-side processing, and it is deleted shortly afterwards.
How does Word Editor let me edit without installing anything?
+
Concretely, the document is parsed into a live text flow rather than a page image, so edits are made to paragraphs and styles and the file is rewritten as a document rather than re-rendered. The editing surface is the browser, so there is nothing to install and no licence to hold.
Anything specific to Word in the editor?
+
Yes — the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images. Worth knowing before you export over your only copy.
Is anything lost when I export?
+
Only what the export format cannot represent. Choose a lossless output while you are still iterating and a compressed one when you are finished — exporting to a lossy format between edit sessions is what accumulates damage.
What can I upload to Word Editor?
+
DOCX and legacy DOC, plus ODT, RTF and plain TXT. LibreOffice does the parsing, so anything it opens correctly on a desktop opens correctly here.
Is there a file size limit on Word Editor?
+
Yes: free accounts process documents up to 25 MB each, and since the text in a Word file is XML, anything near that ceiling is embedded images rather than writing. If a document is over it, the fix is almost always to downsize the images inside rather than to cut content.
Will Word Editor lower the quality of my Word documents?
+
The text, styles, headings, tables and lists are structured data and survive intact — they are not re-typeset. The only thing that can lose fidelity is an embedded image, and only if the operation you chose recompresses it.
Can I run Word Editor on several Word documents at once?
+
Yes. Documents are small and parse fast, so a batch of them is usually finished before a single video would have started.
Why does a EPUB site host Word Editor?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. Word Editor runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once Word Editor is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after Word Editor means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Word Editor here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
