About the Reduce Image DPI Tool
Lower an image’s DPI to shrink its file size and make it web-friendly, or to meet a specific upload requirement. High-DPI print images are often far larger than a website or form needs.
Handy for speeding up web pages, meeting document-upload limits and preparing images for on-screen use. Runs in your browser, keeping your files private.
