Will compression reduce my image quality?

With quality settings above 70%, most images show no visible quality loss to the human eye. You can use the side-by-side preview to find the perfect balance between size and quality.

Can I compress multiple images at once?

Yes. Our batch compression feature lets you upload and compress multiple images simultaneously, saving you significant time.

What Is Image Compression?

Image compression reduces the file size of an image while maintaining acceptable visual quality. There are two types: lossy compression (which slightly reduces quality for much smaller files) and lossless compression (which preserves exact quality). Compressed images load faster on websites, use less storage, and consume less bandwidth. For web developers and content creators, optimizing image size is one of the most impactful performance improvements — Google uses page speed as a ranking factor.
