How to Use the Compression Analyzer

  1. Upload your image by dragging and dropping or clicking the upload area. Supports PNG, JPG, WebP, AVIF, GIF, and BMP formats.
  2. View instant analysis of your image including dimensions, file size, detected image type, and compression efficiency.
  3. Adjust quality settings using the slider to see how different quality levels affect file size across formats.
  4. Compare formats side-by-side to find the best balance of quality and file size for your needs.
  5. Download optimized versions directly or use our specialized compression tools for more options.
Pro tip: For web images, WebP typically offers the best balance of quality and size. Use our Image Upscaler if you need to increase resolution first.

Understanding Image Compression

Lossless

Preserves every pixel exactly. File can be decompressed to identical original. Best for graphics, logos, and screenshots where detail matters. PNG is the most common lossless format. Try our PNG Analyzer to check your files.

Lossy

Discards some data to achieve smaller files. The quality slider controls how much data is removed. JPG uses lossy compression by default. WebP and AVIF support both modes. Use our JPG Analyzer to examine compression artifacts.

Frequently Asked Questions

For most websites, WebP offers the best balance of quality and file size. It's supported by 97%+ of browsers. For maximum compression and modern browsers, consider AVIF. Use PNG for images requiring transparency and pixel-perfect quality like logos. Our Favicon Generator can help create optimized icons.

For photographs: 75-85% provides excellent quality with good compression. For graphics and text: 85-95% preserves sharp edges better. For thumbnails and previews: 60-70% is usually sufficient. The analyzer helps you see the exact tradeoff for your specific image.

PNG is already a lossless format. Converting it to WebP lossless may result in similar or slightly larger files depending on image content. For photographs originally saved as PNG, converting to lossy WebP or JPG will typically reduce size significantly. Check our PNG Compressor for optimization options.

AVIF generally achieves 20-30% better compression than WebP at equivalent quality. However, WebP has broader browser support (97% vs 93%). AVIF also takes longer to encode. For cutting-edge performance, use AVIF with WebP fallback. Convert easily with our WebP to AVIF tool.

All analysis is performed directly in your browser. Your images are never uploaded to our servers. The compression comparisons are generated locally using the HTML5 Canvas API, ensuring complete privacy for your files.
