JPG Compression Quality Settings

The quality setting affects the compression level of the JPG image:

  • 80-100%: High quality, minimal compression artifacts, larger file size
  • 50-75%: Standard quality, good compression, smaller files with some quality loss
  • 10-45%: Low quality, maximum compression, smallest files but visible artifacts

Differences Between Quality Settings

  • 100%: Almost no compression, preserves most original data, largest file size
  • 90%: Very high quality with minimal compression artifacts, good for photography
  • 80%: High quality with light compression, excellent for most web purposes
  • 70%: Good quality with noticeable compression, great for most websites
  • 60%: Medium quality, significant file size reduction, suitable for thumbnails
  • 40%: Low quality, very small file size, visible compression artifacts
  • 20%: Very low quality, extremely compressed, suitable only where file size is critical

Important Notes

  • JPG compression is lossy, meaning some image data is permanently removed
  • Each time you compress a JPG, quality degrades further (avoid re-compressing)
  • For web images, 70-80% usually provides the best balance
  • For high-quality photographs, consider using 85% or higher
  • Text and graphics with sharp edges may show artifacts at lower quality settings

FAQ - JPG Compression

What does this JPG Compressor do? +

This JPG Compressor is an online tool that reduces the file size of JPEG images while maintaining acceptable visual quality. It helps make your websites load faster and reduces storage space needed for images.

Will compression affect image quality? +

JPG compression is lossy, which means some image data is removed to reduce file size. Our tool lets you control the quality level to find the perfect balance between file size and image quality for your needs.

Why should I compress JPG files? +

Compressed JPG files load faster on websites, use less bandwidth, take up less storage space, and improve your site's SEO rankings by enhancing page speed. They're also easier to share via email and social media.

How do I use the quality slider? +

The quality slider lets you control the compression level. Higher values (80-100%) maintain better visual quality but result in larger files. Lower values (10-70%) produce smaller files but may introduce visible compression artifacts. We recommend starting with the default setting of 80% and adjusting as needed.
