- Email Friendly: Fit images under the 10-25MB attachment limits of most email providers
- Save Storage: Free up space on your phone, computer, and cloud storage
- Quick Uploads: Share photos faster on social media, messaging apps, and file sharing services

Image Compression FAQ
How much can I compress an image?
Most images can be compressed by 60-80% without visible quality loss. The exact reduction depends on the image content, format, and your chosen quality level. Photos with lots of detail may compress less than graphics or screenshots.
Is image compression free?
Yes, CompressPixel is 100% free with no limits. Compress as many images as you want, any time. There are no file size limits, no daily caps, and no watermarks. All processing happens in your browser, so there are no server costs to pass on to you.
Does compressing images reduce quality?
Image compression does reduce file size by removing some data, but our smart algorithms ensure the visual quality remains excellent. Most people cannot tell the difference between the original and compressed images when using the recommended "Web Optimized" preset.
Are my images safe? Where are they uploaded?
Your images are 100% safe and private. They are never uploaded to any server. All compression happens directly in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
What image formats can I compress?
You can compress JPG/JPEG, PNG, and WebP images. Our tool also supports format conversion, so you can compress a PNG and download it as a JPG (or vice versa) for additional file size savings.
