Compress a Word document — without uploading it

Shrinks the images inside your document. Nothing uploads.

Where the megabytes are hiding

A .docx is a ZIP archive containing the text, the layout and every image. The text is almost weightless — a hundred-page report is a few hundred kilobytes of actual words. Everything else is pictures, usually pasted straight from a camera or a screenshot tool at full resolution and then scaled down on screen.

The document still carries the original pixels. A photo displayed at postcard size can be a 4000-pixel-wide image behind the scenes.

What compression changes, and what it does not

PackFit recompresses those embedded images and repacks the document. The text, styles, headings and layout are untouched — Word opens the result exactly as before, minus the hidden bulk.

Everything runs in your browser, which matters when the document is a contract, a report or anything you would not hand to an unfamiliar server.

Frequently asked questions

Will my formatting survive?

Yes. Only the embedded images are recompressed; text, styles and layout are repacked untouched.

Why did my document barely shrink?

It is probably mostly text. Without large embedded images there is little to recover.

Is the document uploaded?

No. It is opened, rewritten and saved entirely on your own device.
