Common questions about image compression and optimization
Our tool supports JPEG, PNG, and WebP formats. You can upload images in any of these formats and choose to convert them to a different format during compression for optimal web performance.
Compression results vary based on the original image and quality settings. Typically, you can achieve 50-80% size reduction while maintaining good visual quality. WebP format often provides better compression than JPEG.
No! All image processing happens locally in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security of your files.
You can upload up to 10 images at once, with each image having a maximum size of 50MB. This ensures optimal performance while handling most common use cases including high-resolution photography.
WebP is a modern format that provides superior compression compared to JPEG and PNG. Use it for web images when you need the smallest file sizes and your target browsers support it (most modern browsers do).
The quality slider ranges from 10% (maximum compression, lower quality) to 100% (minimal compression, highest quality). For web use, 70-85% usually provides the best balance of file size and visual quality.
