Step by step
- Check if the file is already small (for example, under 100 KB) or already a low-quality JPG.
- In Word or PowerPoint, make sure you did not check Do not compress images in file.
- If an app still won't shrink it, drop the original image into the box on this page.
- Lower the longest side (for example to 1200 px) and set quality around 60–72%.
- Press Compress and download the smaller file.

Related questions
Why did PowerPoint or Word not compress my pictures?
By default, Office may keep high resolution or have compression turned off in Advanced settings, or the image is linked rather than embedded. Compressing the image before inserting it avoids the issue.
Why is my compressed image bigger than the original?
If you re-save a small, already compressed JPG at a higher quality setting, the file can grow. Lower the quality or reduce the pixel dimensions instead.
What if a photo over 50 megapixels is slow to compress?
Very large photos (over about 50 megapixels) can be slow on older phones. Try compressing on a newer device or desktop browser.
