Shake a file while dragging it to convert it instantly

Hey Product Hunt! 👋 I'm Khoi, the maker of SATF.

I got tired of opening Preview → Export → choose format → choose folder just to turn a HEIC into a JPG. So I built a tiny radial menu that appears right under your cursor when you give a dragged file a little shake.

What you can do:

• Convert images, PDFs, Office docs, video and audio

• Squeeze a photo under 1 MB, resize, remove location info

• Merge several files into one PDF or ZIP

• Park files on the Shelf and drag them out together

It's free and MIT-licensed. Everything runs on your computer: no account, no tracking, nothing uploaded. Native on both platforms (Swift on Mac, C# on Windows), and it updates itself.

I'd love your feedback: which format or edit should I add next? 🙏
