Compress Image — Free & Online
Reduce image file size without noticeable quality loss for faster loading.
Frequently Asked Questions
- What compression method do you use?
- We use a combination of lossy and lossless algorithms depending on the image type. JPG and WebP files use smart lossy compression that targets imperceptible details. PNG files can be compressed losslessly, keeping them pixel-perfect.
- Why is my compressed PNG still large?
- PNG uses lossless compression, which means it can only remove redundant data without affecting any pixels. For dramatically smaller files, consider converting your PNG to WebP — you'll typically save 25-50% with the same visual quality.
- Can I compress multiple images at once?
- The current version processes one image at a time to keep the tool fast and simple. We're working on batch processing — stay tuned.
