Are my MOS files uploaded to a server?

No. All conversion happens in your browser using client-side technology. Your images never leave your device.

What is SD vs HD quality?

SD (Standard Definition) uses lower quality and smaller dimensions for compact files — great for web and social media. HD preserves maximum quality and original dimensions for professional use.

What is the max file size?

Processing is client-side, so there is no server limit. Very large files (50MB+) may be slower depending on your device.

Can I batch convert MOS files?

Currently FxtImg processes one image at a time for best quality. Convert, download, then click "Convert Another" for the next.
