Question 1

Are my images uploaded to a server?

Accepted Answer

No. Compression runs entirely in your browser using JavaScript. Your images never leave your device.

Question 2

Which formats are supported?

Accepted Answer

PNG, JPG, and WebP. The output format matches your input file.

Question 3

How much will the file shrink?

Accepted Answer

Savings vary by image. Photographs typically compress 40-70%. Images that are already heavily compressed will see smaller gains.

Question 4

Will compression affect image quality?

Accepted Answer

The tool targets a maximum output size of 1 MB while preserving as much quality as possible. For most photos the difference is imperceptible.
