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.
