Online Image Compressor

Our compression tool provides specialized optimization for each image format:

JPEG Compression: Adjusts quality and uses chroma subsampling techniques to reduce file size while maintaining visual quality
PNG Compression: Optimizes color data and image complexity while preserving transparency
WebP Compression: Leverages WebP's advanced compression algorithms for optimal file size reduction
GIF Compression: Reduces palette size and optimizes color quantization
BMP Compression: Limited compression options due to format specifications

Low Compression (1-3): Best for images requiring highest quality, such as professional photography
Medium Compression (4-6): Suitable for most web images and general purposes
High Compression (7-9): Best for situations requiring smallest file sizes, such as mobile apps and website loading speed optimization

Higher compression levels may take longer to process but can significantly reduce file sizes, making them ideal for web use and sharing.

To save time, test your compression settings on one or two images first
For website optimization, WebP typically offers the best compression ratio
For compatibility, JPEG for photos and PNG for images with transparency are safe choices
Use the "Maximum Width" option to resize and compress simultaneously for further file size reduction
