Reduce Image Size Free →How to Reduce Image Size Without Losing Quality
Upload your image and set the slider to 50%. At this level, most JPG photos reduce by 60–80% with less than 5% visible quality difference. The tool uses advanced JPEG encoding for photos and palette quantisation for PNG — the same techniques used by TinyPNG and Squoosh.
The key is matching compression level to your use case. Web images tolerate more compression than print. Thumbnails can be compressed more aggressively than hero images. The compressor shows the exact output file size after compression so you can adjust until you hit your target.
Blog & article photos
Start at 50–60% compression. Target output: 100–200KB. Gives fast page load with no visible quality difference.
E-commerce product photos
Use 40–55%. Target: 100–300KB. Product photos need sharpness — go lower on the slider to preserve texture.
Website hero & banner images
Use 50–65%. Target: under 200KB. Hero images have the biggest impact on Largest Contentful Paint (LCP).
Thumbnails & preview images
Use 65–80%. Target: under 50KB. Thumbnails display small so higher compression is fine.
Why Reducing Image Size Matters for Your Website
Images make up 50–70% of a webpage total file size. Uncompressed images slow your site, hurt PageSpeed, and increase bounce rates. Google uses page speed as a ranking signal through Core Web Vitals — specifically Largest Contentful Paint (LCP), which measures how fast the main image on a page loads.
A well-compressed image loads 3–5× faster than the original with no visible difference. After removing product photo backgrounds, reduce your PNG size with the free PNG compressor to keep transparency while cutting file size by 70–90%.
