What features would make a free image converter more useful?

Hi everyone!

I'm building Image Convertor Studio, a free browser-based tool for converting images between formats like JPG, PNG, and WebP, with support for SVG workflows.

My goal is to make image conversion simple and accessible without requiring desktop software.

I'd love to hear from the community:

• Which image formats do you convert most often?

• What features do you wish free image converters offered?

• What's the most frustrating part of your current workflow?

Any honest feedback or suggestions would be greatly appreciated. Thanks!
