How to Compress an Image Without Losing Quality
Reduce JPG and PNG file size for faster pages and smaller uploads while keeping images looking crisp. Here's the practical method.
Smaller images, faster site
Image weight is usually the biggest thing slowing a page down, and page speed is a ranking factor. Smart compression can cut a photo's size by 50–90% with no visible difference for web use.
Compress an image online
Open the Image Compressor, drop in one or many images, and choose Quality mode or Target-size mode. It handles JPG, PNG, and WebP, and everything runs in your browser — your photos are never uploaded.
Two ways to control the result
- Quality mode — drag a slider; 70–80% usually cuts size by half with no visible loss
- Target-size mode — set an exact budget (compress to 100KB, 200KB) and let the tool find the quality for you
- Output as WebP for the smallest files, or keep the original format
- Optionally cap the max width to shrink oversized photos further
Need a different file type instead of a smaller one? Use the Image Format Converter to switch between JPG, PNG, and WebP.
How much can I compress without losing quality?
For photos, expect 50–60% smaller at 70–80% quality with no visible change. Converting to WebP typically saves the most. For logos and graphics with flat color, PNG or lossless WebP keeps edges crisp.
