Frequently asked questions
Does compressing reduce quality?
JPG and WebP use lossy compression, so smaller files mean some quality loss. The slider lets you balance file size against visible quality.
Which formats can I compress?
JPG, PNG and WebP. WebP usually produces the smallest files at a given quality.
Are my images uploaded?
No — compression happens entirely in your browser, so your photos never leave your device.
