Most file converters still push you to upload your files somewhere. Even for basic stuff like changing a PDF or converting an image. It works, but it’s not something you feel great about, especially with random files.
File Converter Pro works like a simple offline converter. You drop files in, pick what you want, and it converts everything locally. No uploads on any server.

File Converter Pro offline file converter for images audio video and documents - Firethering
Most file converters still push you to upload your files somewhere. Even for basic stuff like changing a PDF or converting an image. It works, but it’s not something you feel great about, especially with random files. File Converter Pro works like a simple offline converter. You drop files in, pick what you want, and it converts everything locally. No uploads or any server. The UI isn’t just functional, it actually looks like someone cared. Smooth startup, proper dark mode, small touches that make it feel like a real app instead of a side project. There’s also some extra stuff like stats and achievements. Sounds gimmicky, but it kind of works. You start noticing how often you use it. It’s not lightweight though. And if you want audio or video conversions, you’ll need FFmpeg. But once that’s sorted, you’re done setting things up.
