Client-side compression means the heavy processing (resizing, re-encoding) is done by your computer's CPU using JavaScript and the HTML Canvas API. This avoids slow uploads/downloads to a server.
WebP is a modern format that generally offers superior lossless and lossy compression compared to older JPG and PNG formats. It provides smaller file sizes for the same perceptual quality.
The tool uses PNG quantization (color palette reduction) to reduce file size. For lossy compression, it reduces the number of colors in the image, achieving high file size reduction with minimal visual loss.
Compression might fail if the input image is already highly optimized or if your browser terminates the processing due to resource limits. The tool is designed to keep the original file if the compressed result is larger or equal in size.
Yes, it is completely safe. Since the processing is 100% client-side, your images are never sent over the internet to our servers. They remain private on your device.
