Compress JPG Images Online Free
Compress JPG images — shrink file size with a quality slider and live size preview.
Large image files slow down page loads, eat up storage, and make emails bounce — compressing trades a small, often invisible amount of quality for a significantly smaller file size.
Finding the sweet spot on the quality slider
Very high quality settings barely shrink the file; very low settings introduce visible artifacts (blockiness, blurring) — the useful range for most photos is typically 60-80% quality, where file size drops substantially with minimal visible quality loss.
Frequently asked questions
Why does my website need compressed images?
Large uncompressed images are one of the most common causes of slow page load times, which affects both user experience and search engine rankings — compressing images is one of the highest-impact, lowest-effort website performance improvements available.
Should I resize the image too, or just compress it?
If the image is being displayed smaller than its original dimensions (like a thumbnail), resizing first typically saves far more file size than compression quality alone — this tool's max-width option handles both at once.
