Reduce Image Size
Three ways to make any photo smaller, in one place: hit an exact file size (like 50KB or 1MB) for forms and portals, lower the quality with a live before/after preview, or shrink the width and height in pixels. Everything runs in your browser, so nothing is uploaded.
How to use the Reduce Image Size
- Choose how to reduce: To a file size for upload limits, By quality for the smallest file that still looks great, or By dimensions to change the pixel size.
- Add your image: Drop, paste or browse for a JPG, PNG, WebP, GIF or AVIF image.
- Download: The smaller image updates live as you change the target. Download it when it looks right.

Frequently Asked Questions
How do I reduce an image's size in KB?
Choose 'To a file size', type your target (for example 50KB) and drop your image. The tool finds the highest quality that fits, and only shrinks the dimensions if quality alone can't get there.
What's the difference between file size and image size?
File size is how much storage the image takes (KB/MB). Image size often means dimensions in pixels (e.g. 1920×1080). Reducing dimensions also reduces file size; reducing quality lowers file size without changing dimensions.
How can I reduce image size without losing quality?
Use 'By quality' at 75–85%, or convert to WebP. Both cut size substantially with no visible change. Reducing dimensions keeps images sharp as long as you don't need the extra pixels.
Can I reduce the size of an image on my phone?
Yes. The tool works in Chrome, Safari and other mobile browsers with no app to install, and your photos stay on your phone.
