Frequently asked questions
- Are my images uploaded?
- No. Compression uses your browser canvas, so the image is never sent anywhere. That makes it safe for photographs you would not want on someone else's server.
- Why does my PNG come back as WebP?
- PNG is lossless, so a quality setting does nothing for it and re-encoding usually produces a larger file. WebP keeps transparency and is typically far smaller. Choose JPEG explicitly if you do not need transparency.
- Why did my file get bigger?
- Re-encoding an already well-compressed image at high quality can add bytes. Lower the quality, or keep the original if the result is larger.
- Will compressing lose quality?
- JPEG and WebP are lossy, so some data is discarded. At quality 75 and above the difference is usually invisible at normal viewing size.
