Frequently Asked Questions
Why should I convert images to WebP?
WebP is a highly optimized next-generation graphic format. It supports both lossy compression and lossless alpha transparency, producing significantly smaller file sizes than JPG or PNG, which boosts website load speeds and SEO rankings.
What is the difference between lossy and lossless modes?
Lossless compression preserves every pixel exactly, making it perfect for graphics, logos, and screenshots. Lossy mode discards tiny amounts of visual data to achieve extreme file size reductions, which is ideal for photographic images.
Are my original pictures uploaded to a backend server?
No. The entire conversion process occurs within your browser session using native HTML5 API loops. Your images never leave your computer, ensuring complete confidentiality.
