Frequently Asked Questions
Why is WebP format recommended by Google PageSpeed Insights?
WebP provides superior lossy and lossless compression compared to traditional JPEG and PNG, dramatically speeding up mobile page load times and reducing server bandwidth costs.
Does converting images here resize my pixel dimensions?
By default, your original pixel dimensions are preserved intact. You can also adjust quality quantization sliders to reduce file weight without changing dimensions.
Are my private images uploaded to any remote server?
Never. All compression and format conversion occurs inside your device's HTML5 Canvas memory buffer. No photos are ever uploaded or stored.
