Compress a Word document — make a .docx smaller, free
Compress a Word file by shrinking the photos and screenshots inside it — they are what makes a .docx too big almost every time. Text, tables and layout are left exactly as they are.
Word · PowerPoint → smaller file
Choose a Word document
- Only the pictures inside are made smaller. Text, layout and tables stay as they are.
- Your file never leaves this device: nothing is uploaded.
- Old .doc and .ppt files and files that need a password to open can’t be opened here.
This runs on your device, so a large file with many pictures can take a minute. Keep this tab open.
Videos, sound, fonts, drawings and embedded objects are copied as they are.
Keep your original: pictures can’t be brought back to full resolution later.
Choose the file and it is compressed at once at print quality (220 ppi). Need it under 1 MB or 2 MB for an upload form or an email? Pick that size: the pictures are saved smaller until it fits, and if it can’t, you see the smallest size reached.
How do I reduce the size of a Word file?
Make the pictures in it smaller. Choose your .docx above: LensUp saves the photos and screenshots again for 220 ppi — the print setting Word offers in its own Compress Pictures — and you download the smaller file. If a form asks for a set size, press Under 1 MB, 2 MB, 5 MB or 10 MB. Text and layout are not touched, and the file never leaves your device.
How to compress a Word document
- Choose your Word filePick a .docx of up to 50 MB (200 MB with LensUp Pro), or drop it on the page. It is read on your device; nothing is uploaded.
- Wait a momentThe pictures are saved again for the size they are shown at, targeting 220 ppi. A document with a few photos takes seconds; one with dozens can take a minute.
- Download, or pick a sizeDownload the smaller .docx. To fit a limit, press Under 1 MB, 2 MB, 5 MB or 10 MB, or type a size in KB.
Why Word files get so big
A photo from a phone camera is usually several megabytes, and Word keeps every photo at full size even when it is shown a few centimeters wide. A handful of photos is enough to make a document tens of megabytes; the text itself rarely takes more than a few hundred KB.
What changes, and what stays
Only the pictures are saved again. Each one is resized for the size it appears on the page, targeting 220 ppi, and photos are stored as JPEG; pictures with transparent parts and screenshots stay PNG, and a picture that would not get smaller stays as it is. Everything else — text, fonts, tables, headers, comments and tracked changes — is copied as it is.
What it can’t do
It makes pictures smaller. Parts of the file that are not pictures stay the size they are.
- Old .doc files and files with an open password can’t be opened. Save as .docx in Word, or remove the password, first.
- A document that is mostly text won’t get much smaller: there is nothing to shrink.
- Embedded videos, sounds, fonts, EMF and WMF drawings, GIF pictures and embedded Excel sheets are copied as they are.
- A picture that was made smaller can’t get its full resolution back later. Keep your original.
- A digitally signed document loses its signature in the smaller copy. You are asked before that happens.
Questions
Why is my Word file so big?
Almost always because of pictures. Word keeps each photo at the resolution it was taken at, even when it is shown small on the page, and a phone photo is usually several megabytes. The result screen shows how much of your file is pictures, videos and everything else.
Can I compress a Word document to 1 MB?
Usually, if it is big because of photos. Press Under 1 MB and the pictures are saved at lower resolutions until the file fits. If the text, fonts or embedded objects alone are larger than 1 MB, it can’t fit, and LensUp shows the smallest size it reached and what takes the space.
Does compressing reduce the quality?
Text, tables and layout are untouched. Pictures do lose some detail: by default they are saved for 220 ppi, the print setting Word itself offers, which is usually hard to tell apart on screen or on paper — check large photos before you print. Under a set size they can go lower; small text inside screenshots may then look softer when you zoom in.
Is my document uploaded?
No. Your browser reads the file and makes the smaller copy on your device. Nothing is sent to a server.
Does it work on a phone?
Yes, in the browser of a phone or tablet. A large document with many pictures takes longer on a phone than on a computer.
Can I compress the pictures in Word itself?
Yes: select a picture, open Picture Format › Compress Pictures, untick “Apply only to this picture” and choose a resolution. LensUp does the same to every picture at once, in a current browser, without Word, and can aim for a set file size.
