Image Compressor — frequently asked questions
Will compressing reduce my image quality?
The tool uses lossy compression, so some data is discarded to save space. At medium and high quality settings the change is usually invisible, and you can preview the result before downloading to make sure it looks right.
Which image formats can I compress?
You can compress JPG, PNG and WebP images. JPG and WebP typically shrink the most, while PNG works best for graphics and screenshots with flat colors.
Are my photos uploaded anywhere?
No. The image compressor runs entirely in your browser, so your images are never uploaded. Everything is processed on your own device and nothing is sent to a server.
