Why Compress Images?
Large images slow down websites, increase bounce rates, and hurt your Google ranking. Compressing images reduces file size by 50-80% with minimal visible quality loss. This is essential for web developers, bloggers, e-commerce stores, and anyone who publishes content online. Smaller images also save bandwidth on mobile devices and improve Core Web Vitals scores.
Supported Formats
- JPEG · Best for photos and complex images. Lossy compression with adjustable quality.
- PNG · Best for graphics, logos, and images with transparency.
- WebP · Google's modern format offering smaller files than JPEG/PNG at comparable quality.
Frequently Asked Questions
Does compression reduce image quality?
At the default 60% quality, most images look nearly identical to the original while being 50-80% smaller. Adjust the slider to find the right balance for your needs.
Is there a file size limit?
Each image can be up to 50 MB. Since processing happens in your browser, very large files may take a moment depending on your device.
Are my images uploaded to a server?
No. All compression happens locally in your browser. Your images never leave your device, making this completely private and secure.
What quality setting should I use?
For web use, 60-70% is ideal. For print or portfolios, try 80-90%. For maximum compression (thumbnails, email), 30-50% works well.
