The Complete Guide to Online Image Compression

Images often make up most of a webpage's weight. Whether you are optimizing a site, filling out a form, or preparing travel documents, controlling image size is a practical skill. Our Free Online Image Compressor makes that easier without extra software.

Lossy vs. Lossless: What Actually Happens

Lossy compression (JPEG, WebP) reduces file size by removing data that is less noticeable to the eye. Lossless compression (PNG) keeps every pixel but can still be optimized through metadata cleanup and smarter encoding. Our tool uses the approach that best fits the target size.

Client-Side Privacy by Design

Many online tools upload your image to a remote server before processing it. This tool works entirely inside your browser, so your files stay on your device during compression.

From quick social media resizing to strict government portal submissions, our compressor adapts to every scenario. Try it now - no signup, no limits.

Is my image data safe and private?

What is the difference between lossy and lossless compression?
