What is image compression?
Image compression reduces the file size of an image while keeping as much visual quality as possible. It makes images easier to store, share and use online.
Why compress images?
Smaller image files use less storage and bandwidth and can help pages load faster. Image compression is useful before uploading photos to websites, online stores, blogs and other digital platforms.
Does image compression reduce quality?
It can. Higher compression can produce a smaller file but may reduce image quality. Adjust the quality setting to find the right balance between file size and visual quality.
What is the best image format for smaller file sizes?
The best format depends on the image and how it will be used. WebP and AVIF can often provide smaller files than JPG or PNG while maintaining good visual quality.
Is my image uploaded to a server?
No. The image is processed locally in your browser using the HTML Canvas API. Your original image is not uploaded to a server.
