Frequently Asked Questions
What is WebP format?
WebP is a modern image format that provides superior compression compared to JPEG and PNG. It can reduce file sizes by 25-50% while maintaining the same visual quality.
Is my data safe?
All image processing happens directly in your browser using client-side JavaScript. Your images are never uploaded to our servers or stored anywhere.
What browsers are supported?
Our tool works on all modern browsers. For Safari users, we automatically use JPEG/PNG format with quality optimization instead of WebP for better compatibility.
Can I resize images during conversion?
Yes! You can set a maximum width, and any images larger than that will be automatically resized while preserving the aspect ratio. Smaller images remain unchanged.
Is there a file size or quantity limit?
No limits! You can convert as many images as you want, regardless of their size. However, very large files may take longer to process depending on your device's performance.
