Yes, 100%. All processing is executed by your local browser's Canvas API. Zero bytes of your images are transmitted over the internet, guaranteeing absolute privacy.
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. Using WebP can make your images significantly smaller than JPEG or PNG while retaining the same quality, leading to faster loading websites.
If you try to compress an already highly-optimized image (like an existing WebP) at a very high quality setting, or convert a simple PNG logo into a JPEG, the resulting file might occasionally be larger due to format encoding differences.
