Supports JPEG, PNG, WebP
Large images slow down websites, increase bandwidth costs, and hurt SEO rankings. Image compression reduces file size while maintaining visual quality. Our tool processes images entirely in your browser - your files never leave your device.
We use the HTML5 Canvas API to re-encode images at your chosen quality level. JPEG compression is lossy, removing data the eye barely notices. Lower quality = smaller file size. For most web use, 70-80% quality provides an excellent balance.
Compress JPEG, PNG, and WebP images without noticeable quality loss. Reduce file sizes by up to 80% for faster website loading, smaller email attachments, and more storage space. All compression happens in your browser — your images are never uploaded to any server.
Images typically account for 50-80% of a webpage's total size. Uncompressed images slow down page loading, increase bandwidth costs, and hurt SEO rankings (Google uses page speed as a ranking factor). Compressing images can reduce load times by seconds and improve user experience significantly.
Lossy compression (JPEG) permanently removes some image data to achieve smaller file sizes. At moderate quality settings (70-85%), the difference is virtually invisible to the human eye. Lossless compression (PNG) reduces file size without losing any data, but achieves smaller reductions. Choose lossy for photographs and lossless for graphics with text or sharp edges.
JPEG is best for photographs and images with gradients. PNG is ideal for graphics with transparency, text, or sharp edges. WebP offers superior compression for both use cases (25-34% smaller than JPEG at equivalent quality). AVIF is the newest format offering even better compression but has limited browser support.
For web use, aim for images under 200KB. Use responsive images (serve different sizes for different screen widths). Set JPEG quality between 70-85% for the optimal balance. Always compress images before uploading to your website. Consider using lazy loading for images below the fold to improve initial page load speed.
Typically, images can be reduced by 50-80% without noticeable quality loss. A 2MB photo can often be compressed to 200-400KB with minimal visual difference. The exact reduction depends on the image content, format, and quality setting.
Lossy compression (JPEG, WebP) does reduce quality, but at moderate settings (70-85% quality), the difference is virtually undetectable to the human eye. Lossless compression (PNG optimization) reduces file size without any quality loss.
Yes. All compression happens entirely in your browser using JavaScript. Your images are never uploaded to any server. No data leaves your device. You can verify this by disconnecting from the internet — the tool still works.
Use WebP as your primary format (best compression with good quality). Provide JPEG fallbacks for older browsers. Use PNG only for images requiring transparency or sharp text. Use SVG for logos and icons.
Faster page load times (from smaller images) directly improve SEO. Google uses Core Web Vitals as ranking factors, and large images hurt LCP (Largest Contentful Paint). Compressed images also reduce bandwidth costs and improve mobile user experience.
