How to compress an image
Smaller files
Lower the quality (from 100 down to 50) to shrink the file, and keep the same format or switch to another one. Around 75 keeps photos looking good at a much smaller size.
Which format
JPG and WebP get smaller as quality drops; WebP is usually smallest. PNG stays lossless, so convert screenshots or photos to WebP or JPG when size matters most.
Stays on your device
The work happens in your browser, so the image is not uploaded to our servers. Files up to 15 MB; download the result as PNG, JPG or WebP.
Frequently asked questions
Is compression done on your servers?
No. Your image is re-encoded in the browser. We never receive the image bytes.
Will quality get worse?
Lower quality means smaller files and more visible compression on JPG and WebP. PNG stays lossless unless you convert to JPG or WebP.
