open_in_new Use Smart Compressor FreeJPG compression works by reducing the precision of color data in areas where human eyes are less sensitive. At quality 80–85, compressed JPGs are visually identical to originals but up to 90% smaller. Glopix uses a MozJPEG-compatible algorithm for optimal compression ratios while preserving natural-looking results.

Frequently Asked Questions
What quality should I use to compress JPG for web? expand_more
Quality 80 for most web photos, quality 85 for product images where detail matters (e.g., e-commerce). Quality 70 for ultra-fast-loading thumbnails.
Does compressing a JPG multiple times hurt quality? expand_more
Yes — every re-save of a JPG loses more data. Start with your original high-quality file and compress once to your target quality. Never re-compress an already-compressed JPG if you can avoid it.
What's better — compressed JPG or WebP? expand_more
WebP at the same quality setting will be 25–35% smaller than JPG. For web use, convert to WebP at /imagetools/webp/ for the smallest possible file.
