Image Compressor

Image compression reduces file size by removing redundant data and optimizing the image encoding. Lossy compression (JPEG) removes some image data to achieve smaller sizes, while lossless compression (PNG) maintains all original data but with less dramatic size reduction.

This tool supports JPEG, PNG, and WebP formats for both input and output. You can upload images in these formats and compress them while optionally converting to a different format for better optimization.

Compression can reduce quality depending on the settings. Use the quality slider to balance file size and visual quality. Higher quality settings preserve more detail but result in larger files, while lower settings create smaller files with some quality loss.

For web use, 75-85% quality usually provides a good balance of size and quality. For photography, 85-95% is recommended. For thumbnails or icons, 60-75% is often sufficient. The preview helps you find the right balance for your needs.

Yes, PNG images can be compressed by converting them to JPEG or WebP format. PNG compression is lossless, so direct PNG optimization has limited size reduction. Converting to JPEG or WebP can significantly reduce file size for photographs.

WebP is a modern image format that provides excellent compression with good quality. It typically produces 25-35% smaller files than JPEG with similar quality. It's supported by all modern browsers and is excellent for web use.

File size reduction varies by image type and quality settings. Typical results: JPEG photos can be reduced by 30-70%, PNG photos converted to JPEG can be reduced by 80-90%, and WebP conversion often achieves 25-50% size reduction.
