Image Compressor | SkyConverterTools

Your images are 100% safe and private. All processing happens client-side in your browser. This means:

• Your images never leave your computer
• No files are uploaded to any server
• No data is stored on our servers
• Complete privacy and security
• Your sensitive images remain on your device only

This is the most secure way to compress images, especially for confidential or personal photos.

JPG/JPEG: Best for photographs and realistic images. Uses lossy compression (removes some data). Smaller file sizes but can lose quality at high compression.

PNG: Best for graphics, logos, and images with transparency. Uses lossless compression (no quality loss). Supports transparency but results in larger file sizes.

WebP: Modern format developed by Google. Can be both lossy and lossless. Typically 25-35% smaller than JPG/PNG with similar quality. Supported by all modern browsers.

Compression depends on the image content and format:

• JPG: 70-85% quality typically reduces size by 50-80% with minimal visible loss
• PNG: Lossless, but can reduce size by 20-50% through optimization
• WebP: Can reduce size by 25-35% compared to JPG at similar quality
• Resizing: Reducing dimensions can save 50-90% depending on original size

For most web use, JPG at 70-80% quality is sufficient. Always preview the compressed image to ensure quality meets your needs.

Our tool supports images up to 10MB in size. However, the actual limit depends on:

• Your browser's memory capacity
• Your device's processing power
• Image dimensions (very large dimensions may cause issues)
• Available RAM on your computer

For very large images (over 10MB or high resolution), we recommend resizing first or using specialized desktop software. Most web images should be under 1MB for optimal performance.

By default, we preserve EXIF metadata when possible. However, note:

• JPG: EXIF data is typically preserved
• PNG: Some metadata may be lost during compression
• WebP: Limited metadata support
• Canvas API: Browser limitations may affect metadata preservation

If you need to preserve specific metadata (like GPS location or camera settings), check the "Preserve EXIF metadata" option and verify the output. For critical metadata, consider using specialized software.

Image compression is crucial for web performance:

• Faster loading: Smaller images load faster, improving user experience
• Better SEO: Google ranks faster-loading websites higher
• Mobile optimization: Smaller files use less mobile data
• Reduced bandwidth: Lower hosting costs and better performance
• Storage savings: More efficient use of server/cloud storage
• Accessibility: Faster loading for users with slow connections

• No registration or login required
• No usage limits or quotas
• No watermarks on compressed images
• No file size restrictions beyond browser limits
• All features available for free
• No ads that interfere with compression

We support the tool through non-intrusive ads that don't affect your compression experience. Your privacy and free access are our top priorities.
