Inspect JPG/JPEG image dimensions, EXIF metadata, quality level, compression ratio, and color information.
JPG quality (1-100) affects both visual fidelity and file size. Most images look great at 80-85% quality with significantly smaller file sizes than 100%.
EXIF metadata contains camera settings, date/time, GPS coordinates, and more. While useful, it can increase file size and pose privacy risks.
JPG uses lossy compression to reduce file size. Higher compression means smaller files but more quality loss, especially in detailed areas.
JPG is ideal for photographs with complex colors and gradients. Use 85-95% quality for archival, 70-80% for web.
For web, keep file sizes under 200KB. Consider WebP for even better compression with similar quality.
Strip EXIF metadata before sharing photos online to remove location data and camera information.
Don't use JPG for logos, text, or graphics with sharp edges - use PNG or SVG instead for these.
Pro tip: Use our JPG Compressor to reduce file size while maintaining quality.
JPG (or JPEG - Joint Photographic Experts Group) is the most widely used image format for photographs and web images. It uses lossy compression to significantly reduce file sizes while maintaining acceptable visual quality.
The quality score (0-100) evaluates your JPG based on file size efficiency, quality level, dimensions, and optimization potential. Higher scores indicate better balance between quality and file size for typical web use.
For web images, 70-80% quality is usually sufficient and provides good compression. For print or archival purposes, use 90-95%. Quality above 95% offers diminishing returns with much larger file sizes.
