What is image compression?
Reducing file size by optimizing image encoding parameters, allowing images to occupy less storage space and load faster while maintaining good visual effects.
How to choose compression quality?
Different formats use different optimized quality settings: JPEG at 80, PNG at 75, WebP at 75, AVIF at 60. These settings have been carefully debugged to achieve the best file size while maintaining good visual quality.
JPEG is suitable for photos, small in size but lossy; PNG is suitable for icons and transparent images, lossless but large in size; WebP is a modern format with the highest compression rate, but some older browsers do not support it.
File format conversion tips
Our tool supports format conversion while compressing, such as converting JPEG to WebP for better compression. Selecting multiple output formats can obtain files for different purposes at once.
Up to 20 image files can be uploaded at a time. It is recommended to test the compression settings with one image first, and then batch process after confirming the effect is satisfactory. All processing is done locally in the browser, protecting your privacy.
After compression is complete, you can download each file separately or download all files in a package. Files are automatically renamed to distinguish formats.
