Everything About Image Compression
Get answers to common questions about compressing and converting images.
Image compression reduces file size by removing redundant data and applying mathematical algorithms. Lossy compression (JPEG, WebP) removes some image data to achieve smaller sizes, while lossless compression (PNG) reduces size without any quality loss. Our tool uses advanced algorithms to find the optimal balance between file size and visual quality.
JPEG/JPG is best for photographs with good compression but doesn't support transparency. PNG is ideal for graphics and logos with lossless compression and transparency support. WebP is a modern format offering 25-35% better compression than JPEG with transparency support. HEIC is Apple's format offering excellent compression, mainly used on iOS devices.
It depends on the compression settings. Using higher quality settings (75-90%) typically produces no visible quality loss while still reducing file size significantly. Lower quality settings (20-50%) will produce smaller files but may show visible artifacts. Our tool lets you preview the result before downloading.
Typical compression can reduce file sizes by 50-90% depending on the original image and settings. Photos can often be reduced by 60-80% with minimal quality loss. WebP format typically provides 25-35% better compression than JPEG.
