Why Compress Images?
Large images slow down websites, take longer to send by email, and eat into storage. Compressing images reduces their file size while keeping them looking sharp.
Typical results:
- A 5MB JPG photo → compressed to 400KB (92% smaller)
- A 2MB PNG screenshot → compressed to 300KB (85% smaller)
- A 1MB WebP → compressed to 120KB (88% smaller)

Frequently Asked Questions
Will compressing an image reduce its quality?
Pixlush uses smart compression algorithms that reduce file size while preserving visual quality. At standard settings, the difference is undetectable to the human eye.
What image formats can I compress?
Pixlush supports JPG, PNG, and WebP compression.

How do I compress an image below 100KB?
You can adjust the quality slider to find the perfect balance. For the best results, try converting large images to WebP format, which offers superior compression compared to JPG or PNG.

We recommend a quality setting of 80%. This typically reduces file size by 70-90% while maintaining high visual fidelity for web and mobile displays.
