About this tool
Why use a local Image Compressor?
Most online image compressors require you to upload your files to their servers. This is not only slow for large images, but also a massive privacy risk for sensitive screenshots or proprietary design assets.
Native Canvas API
This tool leverages the HTML5 Canvas API built directly into your web browser. When you drop an image, the browser loads it into memory, draws it on a hidden canvas, and exports it to your desired format and quality without a single byte ever leaving your device.
The Power of WebP
We highly recommend converting large PNGs and JPEGs into the WebP format. WebP provides superior lossless and lossy compression for images on the web, often shrinking file sizes by 30-50% with zero noticeable drop in quality.
