When PNG makes sense
PNG is great for screenshots, UI graphics, icons, and images with sharp lines. It can preserve details without introducing JPEG artifacts, and it supports transparency.
What to expect from PNG compression
PNG is usually lossless, so size reductions can be smaller than JPG or WebP depending on the image. Simple graphics often optimize well, while complex photos may not shrink much as PNG.
Want a smaller file?
If you want maximum size reduction, try exporting to WebP. WebP often produces much smaller files while keeping good visual quality.
Private by design
Your images are processed locally in your browser. That helps keep your files private and avoids upload time.
