Image Compressor

Large image files are one of the biggest contributors to slow website load times. Compressing images reduces their file size without a noticeable loss in visual quality, which improves page speed, reduces bandwidth usage, and provides a better user experience on mobile devices. Search engines also factor page speed into rankings, so optimized images can directly improve your site's SEO performance.

JPEG is best for photographs and complex images with many colors. It uses lossy compression, so lowering the quality slider reduces file size at the cost of some detail. WebP is a modern format that typically achieves 25-35 percent smaller files than JPEG at equivalent visual quality, and it is supported by all major browsers. PNG uses lossless compression, making it ideal for graphics with sharp edges, transparency, or text, but the files tend to be larger. Choose the format that best matches your use case.

For web use, a quality setting of 70-80 percent for JPEG or WebP usually provides an excellent balance between file size and visual quality. Use the social media size presets to quickly resize images for platforms like Instagram, Twitter, or YouTube without manual calculations. If your original image is much larger than needed, resizing it down before compressing will yield the biggest file size savings. Always preview the compressed result before downloading to make sure the quality meets your standards. If you need to change file formats as well, our Image Converter supports PNG, JPG, WebP, and more. For combining compressed images into documents, check out our PDF Merge tool.
