Image optimization is the process of reducing image file sizes while maintaining visual quality. It's crucial for web performance because:

• Faster page loading times improve user experience
• Reduced bandwidth usage saves costs
• Better SEO rankings due to improved page speed
• Lower bounce rates and higher engagement

No, absolutely not. All image processing happens directly in your browser using client-side technology. Your images never leave your device, ensuring complete privacy and security. We don't store, upload, or access your images in any way.

There are no artificial limits on our platform. However, processing is limited by your device's capabilities (RAM and processing power). Most modern devices can easily handle dozens of images simultaneously in batch processing mode.

WebP is generally the best format for web use as it provides 25-35% better compression than JPEG while maintaining similar quality. For browsers that don't support WebP:

• JPEG: Best for photographs and complex images
• PNG: Best for graphics, logos, and images requiring transparency
• GIF: Only for simple animations (consider WebP or video for better quality)

Use JPEG for:

• Photographs with many colors
• Images where small quality loss is acceptable
• When smaller file size is priority

Use PNG for:

• Images requiring transparency
• Graphics, logos, and text
• Images with few colors
• When perfect quality is required

The optimal compression depends on the image type:

• JPEG: 80-85% quality for web use without noticeable loss
• PNG: Lossless compression, but file sizes remain larger
• WebP: Can achieve 60-70% quality with better results than JPEG at 85%

For most web applications, 70-80% quality provides an excellent balance between file size and visual quality.

Lossy compression permanently removes some image data to achieve smaller file sizes. Examples include JPEG compression. The image quality is reduced, but often imperceptibly.

Lossless compression reduces file size without removing any image data. The original quality can be perfectly restored. PNG uses lossless compression.

For web use, lossy compression is usually preferred due to significantly smaller file sizes.

Yes! Our batch processing feature allows you to:

• Upload multiple images simultaneously
• Apply the same settings to all images
• Process them with one click
• Download all processed images together

This saves significant time when working with large numbers of images.

Our tools support all major image formats:

• Input: JPEG, PNG, WebP, GIF, BMP, TIFF
• Output: JPEG, PNG, WebP, GIF, BMP

We're continuously adding support for more formats based on user needs.

WebP offers several advantages over JPEG:

• 25-35% smaller file sizes at the same quality level
• Support for both lossy and lossless compression
• Transparency support (like PNG)
• Animation support (like GIF)

The main limitation is browser support, though over 95% of browsers now support WebP.

Signs that your images need optimization:

• File sizes over 100KB for web images
• Slow page loading times
• High bandwidth usage
• Poor performance on mobile devices
