Image Compressor
Compress images to reduce file size while maintaining quality. Perfect for web optimization, email, and social media.
💡 Tips for Best Results
- JPEG: Best for photos and images with gradients. Quality 70-85% is usually optimal
- PNG: Best for graphics, logos, and images with transparency
- WebP: Modern format with excellent compression and quality balance
- Lower quality = smaller file size, but may reduce visual quality
- All processing happens in your browser - your images never leave your device
Frequently Asked Questions
What is the best image format for the web?
For photos: WebP is best (30–50% smaller than JPG at equal quality), with JPG as fallback. For graphics, logos, and images with transparency: PNG or WebP. For animated images: WebP or GIF. This tool compresses JPG and PNG directly in your browser.
How much can I compress an image without losing quality?
For JPEGs, quality settings of 75–85% are typically indistinguishable from the original to the human eye, while reducing file size by 50–70%. For PNGs, lossless compression can reduce size by 20–40% with zero quality loss. This tool lets you preview before saving.
What is the difference between lossy and lossless compression?
Lossless compression (used for PNG) reduces file size without discarding any pixel data — the decompressed image is bit-for-bit identical to the original. Lossy compression (used for JPEG) permanently discards some image data to achieve higher compression ratios. Once saved as lossy, quality cannot be recovered.
What image file size should I aim for on web pages?
For images above the fold (hero/banner): under 200 KB. For thumbnails and supporting images: under 50 KB. Large images are one of the top causes of slow page load times and poor Core Web Vitals (LCP) scores, which affect both user experience and Google rankings.
Does image compression affect SEO?
Yes, indirectly but significantly. Faster page loads improve Core Web Vitals (especially Largest Contentful Paint), which Google uses as a ranking signal. Compressed images also reduce bandwidth costs and improve mobile experience. Always compress images before uploading to your site.
