Why reduce image file size?
Reducing image file size is useful when uploading images to websites, submitting online forms, attaching images to emails, publishing content, or optimizing images for web pages. Smaller files generally require less storage and less data to transfer.
Compress JPG, PNG, and WebP images

Compress images to a target file size
Some websites and applications impose maximum upload limits. If you need an image below a specific threshold, such as 100 KB, 200 KB, or 500 KB, targeting a maximum file size can make the image easier to submit while still preserving useful visual quality.
Image compression directly in your browser
The image compression workflow is designed to run directly in your browser. This means you can optimize an image without needing to install desktop image-editing software or rely on a traditional server-based image compressor.
