Image compression is the process of reducing the file size of images while maintaining visual quality. This is achieved by removing redundant data or using more efficient encoding methods.

Our image compressor supports the most common web image formats:

• JPG/JPEG - Best for photos with many colors
• PNG - Best for images with transparency or few colors
• WebP - Modern format with excellent compression

Our tool uses HTML5 Canvas technology to:

• Resize images to your specified maximum dimensions
• Apply quality compression based on your settings
• Re-encode the image with optimized settings
• Preserve the original format and metadata when possible

Yes! All image processing happens directly in your browser using Canvas API. Your images are never uploaded to our servers, ensuring complete privacy and security.

Quality settings guide:

• 90-100% - Highest quality, minimal compression
• 80-90% - High quality, good for web use
• 60-80% - Good quality, smaller file size
• 40-60% - Lower quality, significant compression

We recommend starting with 80% for the best balance of quality and file size.
