Frequently asked questions
What image formats can I compress?
The tool supports JPEG and PNG images. WebP input is also accepted in modern browsers. The output format matches the original input format.
How much will my image be compressed?
Results vary by image content. Moving the quality slider lower produces smaller files at the cost of some visual fidelity. The tool displays both the original and compressed file sizes so you can find the right balance.
Are my images uploaded to a server during compression?
No. All compression is performed locally in your browser using the browser-image-compression JavaScript library. Your images are never sent anywhere.
