How to Use & Features
Compress Image Online for Free — Fast, Private & Unlimited
Large images slow down your website, eat up storage, and take forever to send by email. Our free online image compressor lets you compress JPG and PNG images at light speed, right inside your browser. No uploads, no queue, no watermarks — just a smaller file in seconds.
Unlike most tools, ImagePixa is a true browser-based image compressor. Your photos never leave your device, so it's perfect for sensitive screenshots, client work, or any image you'd rather not upload to an unknown server.
How to compress an image online in 3 steps
1. Upload your image
Drag and drop your JPG, PNG, or WebP file into the box above, or click to pick one from your device. Nothing is uploaded anywhere.
2. Pick your quality
Use the quality slider to balance file size and visual quality. 80% is a great default for most photos. Lower values = smaller files.
3. Download
Hit "Compress Image" and download your optimized file instantly. See exactly how much space you saved before downloading.
