Everything About Image Compression
Image file size is one of the biggest bottlenecks for website loading speed. Unoptimized high-resolution images can reach several MB, significantly slowing page loads. This tool drastically reduces file sizes while maintaining visual quality — essential for web performance optimization. For blogs, e-commerce, and portfolio sites, image optimization alone can improve loading speed by 50% or more.
The quality slider gives free control from 1 to 100. At quality 80, the difference from the original is virtually imperceptible to the human eye, yet file size drops 60-70%. Below quality 60, degradation becomes visible but file size decreases over 80%. Find the right balance for your specific use case.
Batch upload multiple images for simultaneous compression, saving significant time. Compare original vs compressed file sizes for each image to instantly verify compression effectiveness. All processing happens in the browser — images never leave your device, guaranteeing privacy.
Pro tip: When email attachments hit size limits (usually 25MB), image compression can solve the problem. Compressing before social media uploads also speeds up the upload process. Web developers who receive "optimize images" recommendations from Google PageSpeed Insights should use this tool. Quality 70 for thumbnails and 85 for hero images are good starting points.
