Frequently asked questions

Our compressor reduces file size by optimizing the image data. For JPGs, it adjusts the quality level. For PNGs, it reduces the color palette. The result is a smaller file that still looks great.
Some quality reduction is normal with lossy compression (JPG, WebP). However, our default settings are optimized to keep the visual difference barely noticeable. You can adjust the quality slider to find your preferred balance.
No. Your image is processed entirely in your browser. It never leaves your device. We use client-side JavaScript to handle the compression.
You can compress images up to 50 MB in size. For best performance, we recommend files under 20 MB.
