Compress Images Online Free

Image compression is about finding the sweet spot between file size and visual quality. Too much compression and your photos look terrible - blocky artifacts, blurred details, weird colors. Too little compression and files are massive, taking forever to upload or email. Our image compressor aims for that middle ground where file size drops significantly but quality remains good enough for the intended use. Here's what most people don't realize: different image types need different compression strategies. Photos (JPEGs) are already compressed, so "compressing" them means re-compressing at lower quality. This is lossy - you lose some detail. But if you go from 95% quality (huge file) to 75% quality (much smaller), most people can't see the difference on screens. PNGs are often unnecessarily large because they use lossless compression. Converting them to optimized JPEGs can reduce file size by 80% with minimal visible change. Screenshots and graphics with text need different handling than photos - too much JPEG compression makes text blurry. Keep those as PNGs but optimize the PNG compression. Our tool analyzes your image type and applies appropriate compression. For photos, we use smart JPEG optimization that reduces file size without obvious quality loss. For graphics, we optimize PNG compression or convert to efficient JPEGs where appropriate. You control the compression level: maximum (smallest files, noticeable quality reduction), balanced (good size reduction, minimal visible change), or custom.
