Image Compressor
Transparent areas become white in a JPEG. Choose WebP to keep them.
Both previews show the middle of the image at full size, so you can see what compression does to the detail.
How it works
Pick an image and choose how to compress it. Quality lets you trade detail for size with a slider. Target size finds the best quality that fits under a limit, like the 50 KB many application forms ask for. The image keeps its width and height either way.
JPEG or WebP?
JPEG opens everywhere and is what most forms accept. WebP is smaller for the same quality, and keeps transparent areas, but some older sites won't take it.
When it won't go small enough
A large photo can't always be squeezed under a small limit just by lowering the quality. Make it smaller in pixels first with the Image Cropper, which can set an exact size, then compress the smaller copy.
Your image stays with you
The image is compressed inside your browser. It isn't uploaded, so nothing is stored anywhere once you close the page. Saving a new copy also leaves out the details your camera stored with the photo, such as where it was taken.
