Frequently Asked Questions

How much can I reduce my image size?

Typically 50-90% reduction depending on the original image and quality setting. A 5MB photo can often be reduced to under 500KB while still looking great.

Will compression reduce image quality?

Some quality loss is inevitable with lossy compression, but at 80% quality most people cannot see any difference. Use the preview to find your ideal balance.

Is my image uploaded to a server?

No! All compression happens locally in your browser using JavaScript. Your images never leave your device.

What's the best quality setting for WhatsApp?

For WhatsApp, 70-80% quality works great. This gives you significant size reduction while keeping photos looking sharp on mobile screens.

Can I compress multiple images at once?

Yes! Our batch compression feature lets you compress dozens of images simultaneously with the same quality settings.
