How Does Our Image Compressor Work?
Our advanced image compression algorithm reduces file size through multiple optimization techniques including lossy and lossless compression, metadata removal, and smart quality adjustment. All processing happens in your browser for maximum privacy and security.
Compression Levels Explained:
- Low Compression: Maintains highest quality with minimal size reduction (10-30% smaller)
- Medium Compression: Best balance of quality and size reduction (30-60% smaller) - Recommended
- High Compression: Significant size reduction with good quality (60-80% smaller)
- Extreme Compression: Maximum size reduction for web optimization (80-90% smaller)
Supported Image Formats:
- JPEG/JPG: Best for photographs and images with many colors. Excellent compression ratio.
- PNG: Perfect for images with transparency, logos, and graphics with sharp edges.
- WebP: Modern format offering 25-35% better compression than JPEG while maintaining quality.
Pro Tips for Better Compression:
- Use JPEG for photos and WebP for modern browsers to get the best compression
- Resize large images to your target display size before compressing
- Medium compression level works best for most use cases
- Convert PNG photos to JPEG for significantly smaller file sizes
- Always preview compressed images to ensure acceptable quality
Privacy and Security:
- All image processing happens locally in your browser
- No images are uploaded to our servers
- Your images never leave your device
- No registration or personal information required
- Completely free with no hidden costs or limitations
Frequently Asked Questions
How much can I compress my images?
Compression results vary by image type and content. Typically, you can expect 30-80% size reduction. Photos compress better than graphics, and JPEG format generally achieves higher compression ratios than PNG.
Will compressing images reduce quality?
Our compression algorithm is designed to maintain visual quality while reducing file size. With medium compression settings, most users won't notice any quality difference. Higher compression levels may show slight quality reduction but significant space savings.
Is there a limit to how many images I can compress?
No, there are no limits! You can compress as many images as you want, with no file size restrictions. Our tool processes everything locally in your browser, so you're only limited by your device's memory.
What image formats are supported?
We support JPEG, PNG, and WebP formats for input. You can also convert between formats during compression. WebP offers the best compression efficiency and is recommended for web use.
Can I compress images for specific use cases?
Yes! Use low compression for print materials, medium for general web use, high for email attachments, and extreme for web thumbnails or when bandwidth is limited.
Do you store my images on your servers?
Absolutely not! All image processing happens entirely in your browser. Your images never leave your device, ensuring complete privacy and security.
