Compress a Word (DOCX) File
Compress DOCX files online by optimizing embedded images — text, formatting, tracked changes and comments untouched.
How to use Compress DOCX
Word documents balloon when full-resolution phone photos get pasted in. The tool re-compresses those embedded images at your chosen preset while leaving text, styles, tracked changes, comments, headers and footers completely untouched — the document opens and edits exactly as before, minus most of the weight. Email attachment limits stop being a problem.
- Drop your file into the box above, or click it to browse. You can also paste from the clipboard.
- Adjust the options to taste — the defaults are sensible for most cases.
- Press Compress and watch the progress bar; everything runs on your device.
- Download your result — individually, or as a ZIP when there are several files.
Like every tool on ImageCompressorKits, this runs 100% in your browser: your file is never uploaded to any server, which makes it safe to use even with private documents — and it keeps working if you go offline after the page loads.
Frequently asked questions
Are my tracked changes and comments safe?
Completely — the document's XML, which holds all text, revisions and comments, is copied through byte-for-byte. Only image streams are re-encoded.
Can Word still edit the file afterwards?
Yes, it remains a fully standard .docx. Nothing about the format changes; only the pictures inside weigh less.
Is this tool really free?
Yes — completely free, with no signup, no watermark, and no file limits beyond what your device's memory can handle.
Are my files private?
Yes. Processing happens locally in your browser via JavaScript; nothing is transmitted or stored. See our privacy policy for the full picture.
