Frequently Asked Questions
How does the converter compress image file sizes without ruining quality?
It uses HTML5 Canvas interpolation alongside custom WebP/JPEG quantization to strip redundant visual noise while preserving crisp details.
Are my private photos or financial documents uploaded to any databases?
No. Files are processed locally as binary arrays inside your browser RAM. Your data never touches external cloud servers.
Why is WebP compression highly recommended for websites?
WebP is a modern image standard created by Google. It offers superior compression for web graphics, saving up to 30% of file size compared to JPEG.
