How does image compression work?

Our tool uses intelligent compression algorithms to reduce file size while maintaining visual quality. It adjusts quality settings iteratively to reach your target file size.

Will compression affect image quality?

Some quality loss is inevitable with compression, especially for aggressive targets. Our tool finds the optimal balance between file size and quality.

Can I compress PNG images?

PNG compression in our tool converts to a compressed format. For lossless PNG compression, the file size reduction may be limited.

What's the best format for compressed images?

WebP offers the best compression-to-quality ratio for most images. JPG is ideal for photographs, while PNG is better for images with transparency.
