Advanced Image Compressor

What image formats do you support?

Our compressor supports all major image formats including JPG, PNG, HEIC, WEBP, GIF, and BMP. We can process up to 10 images simultaneously with each file size up to 20MB. The output format can be set to match the original or converted to JPG/WebP for better compression.

How does image compression work?

Our compression technology uses advanced algorithms to reduce file size while preserving visual quality. Techniques include:

• Smart quantization for JPEG images
• Optimized color palette reduction for PNG
• Efficient WebP encoding for modern browsers
• Intelligent resizing based on maximum dimensions
• Selective metadata removal (EXIF, GPS data)

Will compression reduce image quality?

Our compression maintains excellent visual quality while reducing file size. You can control the balance between size and quality using the quality slider:

• 85-95%: Near-lossless, minimal quality difference
• 70-85%: Recommended balance (good quality with significant savings)
• 50-70%: Noticeable quality loss but much smaller files
• Below 50%: Significant quality loss for maximum compression

What are the benefits of image compression?

Compressing images provides multiple advantages:

• Faster website loading: Smaller images load faster
• Reduced bandwidth usage: Save on data transfer costs
• Improved SEO: Page speed is a ranking factor
• Storage savings: Store more images in limited space
• Better user experience: Faster-loading pages keep users engaged

How do I download compressed images?

After compression, you have two options:

1. Individual download: Click the download button next to each compressed image
2. Batch download: Use the 'Download All as ZIP' button to get all compressed images in a single ZIP file

The original files remain untouched on your device.

Is my image data secure?

Absolutely. Our compression happens entirely in your browser:

• Images are never uploaded to any server
• Processing occurs locally on your device
• No images are stored or transmitted
• No account or login required

When you close the browser, all processed data is cleared automatically.

What are the advanced options?

Our advanced settings include:

• Preserve EXIF metadata: Keep camera information and GPS data
• Batch mode: Apply settings to all images at once
• Progressive rendering: Create progressive JPGs for faster perceived loading
• Format conversion: Convert all images to JPG or WebP

Can I compress HEIC images from iPhone?

Yes! We support HEIC format commonly used by iPhones. Our compressor:

• Converts HEIC to standard formats (JPG/PNG)
• Preserves image quality during conversion
• Reduces file size significantly compared to original HEIC
• Handles multiple HEIC files simultaneously

HEIC images are processed locally - no server upload required.
