Compress JPG and JPEG online
Reduce the size of your JPEG files without visible quality loss. Our intelligent algorithm analyzes each image to optimize compression while preserving important details. Ideal for reducing the weight of your photos before sending by email or publishing on a website. JPEG compression works particularly well on photographs with natural gradients.
PNG compression with transparency
Optimize your PNG images while preserving alpha transparency. PNG files are often large because they use lossless compression. Our tool intelligently reduces the number of colors and optimizes the palette to decrease file size by up to 70% while maintaining excellent visual quality.
Why compress your images for web?
Light images significantly improve your site's loading time, which directly impacts your Google ranking (Core Web Vitals) and user experience. A page that loads in under 3 seconds retains more visitors. Compressing your images before publishing is an essential SEO best practice.
WebP compression: the modern format
WebP is the next-generation image format developed by Google. It offers 25-35% better compression than JPEG and PNG, while supporting transparency and animation. Convert your images to WebP for an ultra-fast website compatible with all modern browsers.
Compress photos for email and social media
Reduce your photos to meet email attachment size limits (typically 10-25 MB) or optimize them for Facebook, Instagram and Twitter. A 5 MB smartphone photo can be reduced to 500 KB with no visible difference, making quick sharing easy.
