What is image compression?
Image compression makes a picture's file smaller so it uploads faster, fits email limits and saves storage. JPG and WebP use lossy compression, which removes detail your eye rarely notices. PNG uses lossless compression, which keeps every pixel but usually shrinks less.
Can I compress an image and keep it clear?
Yes. High Clarity keeps the most detail, so text and edges stay sharp. It saves less space than Balanced or Smallest File, but the photo still gets lighter.
Where can I compress images?
Right here, in any web browser on a phone, tablet or computer. There is nothing to install and no account to create. Your photos are processed on your device, so they are not sent to a server.
Why compress images?
Smaller images help you pass upload limits on forms, job portals and exam sites, load web pages faster, and free up space on your phone.
