Frequently Asked Questions
Is this image compressor really free and private?
Yes, it is completely free with no limits on how many times you can use it. Because the image compression happens entirely in your browser, your files are never uploaded to any server. Your privacy is fully guaranteed.
Which image format is best for websites?
WebP is the recommended format for most websites because it provides superior compression compared to JPEG and PNG. It helps your pages load faster and improves your Core Web Vitals.
How does image compression affect page speed?
Large images are the most common reason for slow page loading. By compressing images, you reduce the total page size, which directly improves loading times and metric scores like Largest Contentful Paint (LCP).
Will I lose image quality?
The default quality setting of 78 offers a good balance between file size reduction and visual quality. The changes are nearly invisible to the human eye, but the file size reduction is massive.
