Image Compressor & Resizer
Shrink photos for the web without uploading them anywhere.
A photo straight off a camera can be 6 MB; the same picture on a web page rarely needs more than 150 KB. Drop images here to resize and compress them in your own browser - nothing is uploaded, so it works on client photos you would not want to hand to a website.
