How to make a Word, Excel or PowerPoint file smaller

Drop the file. The pictures inside are scaled and re-encoded in your browser, then the package is written again. The text, the styles and every other part stay as they were.

  1. Drop the file

    A .docx, .xlsx or .pptx, one at a time.

  2. Choose the picture size

    1600 px on the long edge is the default; 1200 is smaller, 2400 is sharper.

  3. Read before and after

    The cards show the old size, the new size, the saving and how many pictures were made smaller.

  4. Download

    If the new file is not smaller, the download is the original.

Frequently asked questions

Not answered here? Ask Yangopen

Which files can I compress?

A .docx, .xlsx or .pptx file whose content types name a Word, Excel or PowerPoint main part. Anything else is refused, including a zip of pictures.

Is my file uploaded?

No. The file is read and written in your browser; it never goes to our server.

What happens to the pictures?

JPEG and opaque PNG pictures larger than the chosen long edge are scaled and re-encoded in their own format, and kept only when the result is smaller. A PNG with transparency is kept as PNG. SVG, EMF, WMF, GIF and unknown pictures are copied unchanged.

Does it change the text or the document layout?

No. Every part other than a picture is copied byte for byte under the same name, and the XML is not edited.

Why is the file not smaller?

The pictures may already be small or well compressed. Try 1200 px, or accept the original: the page says when the result is not smaller and offers the original.

Can it open a password-protected file?

No. A password-protected Office file is an OLE file, not a zip. Remove the password in Office, save it again, then compress it.
