Free Image Optimizer

• Reducing page load times (Google ranks faster sites higher)
• Decreasing bandwidth usage and server costs
• Improving user experience with faster content display
• Boosting SEO through better Core Web Vitals scores
• Increasing conversion rates (faster sites convert better)

Lossy compression reduces file size by permanently eliminating certain information (especially redundant data) which may affect image quality at higher compression levels.

Lossless compression reduces file size without losing any quality, but typically achieves smaller size reductions compared to lossy methods.

Our tool automatically applies the optimal compression method based on your quality settings.

JPEG: Best for photographs and complex images with many colors

PNG: Ideal for graphics with transparency or simple illustrations

WebP: Modern format offering superior compression (25-35% smaller than JPEG)

When in doubt, select "Auto-optimize" and our tool will choose the best format.

• 85-95%: High quality (minimal compression, best for print)
• 70-85%: Balanced quality (good for web, small quality loss)
• 50-70%: High compression (visible quality loss, smallest files)
• Below 50%: Extreme compression (significant quality loss)

For most websites, 75-85% provides the best balance of quality and file size.

• JPEGs: 60-80% reduction without noticeable quality loss
• PNGs: 50-70% reduction (lossless) or 70-90% (lossy)
• WebP: Additional 25-35% reduction compared to optimized JPEG/PNG

Results vary based on original image quality and content type.

• Upload multiple images simultaneously (no limit)
• Apply the same settings to all images or customize individually
• Download all optimized images as a single ZIP file
• Process hundreds of images in one session

• Are completely free of watermarks
• Maintain full copyright ownership
• Can be used commercially without attribution

We never modify your images beyond the compression you specify.

• Your images never leave your computer
• No files are uploaded to external servers
• No third-party has access to your images
• Processing happens 100% locally in your browser

This makes our tool ideal for sensitive or confidential images.

• Smaller files: 25-35% smaller than equivalent quality JPEG
• Transparency: Supports alpha transparency like PNG
• Modern support: Compatible with all major browsers
• Better compression: Advanced predictive coding

The only downside is slightly slower encoding time, which our tool handles automatically.

• Specify maximum width and/or height
• Maintains original aspect ratio automatically
• High-quality Lanczos resampling algorithm
• Combine resizing with compression for maximum savings

Resizing before compression often yields the best file size reductions.

• Faster processing: Optimized algorithms work in seconds
• Easier to use: No complex settings or expertise needed
• Better compression: Often achieves smaller files at same quality
• Batch processing: More efficient than Photoshop actions
• Free: No expensive software license required

• Zero image data is transmitted to our servers
• No EXIF or metadata is collected
• Your browsing session is completely private
• We don't use tracking cookies or analytics pixels

You can verify this by using the tool offline or checking network requests in your browser's developer tools.
