Compress JPG, PNG & WebP images 鈥?up to 90% smaller, minimal quality loss
Image compression reduces the file size of an image while maintaining acceptable visual quality. Smaller images load faster on websites, improve user experience, boost SEO rankings, reduce bandwidth costs, and save storage space. This tool uses advanced compression algorithms to minimize file size with minimal quality loss.
Website optimization: faster page load times and better SEO. Email attachments: reduce file size to fit email limits. Social media: optimize images for faster uploads. Storage savings: reduce disk and cloud storage usage. Mobile apps: smaller images mean faster app loading times.
Click the upload area or drag & drop images onto it. Adjust the quality slider 鈥?lower quality means smaller file size. Optionally set max width and/or height to resize images. Compression starts automatically. View before/after file sizes and savings percentage. Download individual images or all at once.
No. All image compression happens locally in your browser using JavaScript. Your images are never uploaded to any server, never stored, and never seen by anyone else. This is a 100% client-side tool.
For most web use, 70-80% quality provides excellent results with significant file size reduction. For photos where quality is critical, use 85-90%. For thumbnails or previews, 50-60% may be sufficient. Always check the result visually.
Lossy compression (JPG, WebP) reduces file size by discarding some image data 鈥?quality decreases slightly but file sizes are much smaller. Lossless compression (PNG) preserves all data but has limited compression ratios. This tool uses lossy compression for maximum file size reduction.
Results vary by image type. Photos typically compress to 20-30% of original size at 70% quality. Screenshots and images with lots of text compress less well. PNG images with transparency can see 50-80% reduction when converted to WebP.
Resizing (setting max width/height) reduces pixel dimensions, which naturally reduces file size. It's often more efficient to resize first, then compress. For web images, always resize to the actual display size 鈥?there's no benefit to loading a 4000px image if it's only displayed at 800px.
