FAQ
What formats are supported?

What are the advantages of WebP format?
WebP is a format developed by Google. At the same quality, the file size is about 30% smaller than JPG, making it ideal for web use and significantly improving website loading speed.
Will conversion cause quality loss?
JPG/WebP are lossy formats with slight quality loss, while PNG/BMP are lossless formats with no quality loss. You can adjust the quality slider to balance image quality and file size.
Can I convert animated GIFs to other formats?
