InstaFit

InstaFit is a photo resizing tool I built after running into the same problem over and over: photos that looked great on their own still needed extra work to fit cleanly into Instagram posts.

I wanted a faster path than manually reworking everything in Canva, so I made a tool that handles the format problem with a simple workflow and no unnecessary friction.

What the tool does

Resize photos for Instagram posts without the usual detour.

The point of InstaFit is not to be a giant editor. It is to solve one annoying, repeatable step cleanly so posting feels easier.

Why it matters

Simple, free, and browser-based.

There was no free, ad-free fix that handled the whole job the way I wanted. So I built one that runs entirely in the browser, with no images uploaded to any server.

  • Stage: shipped side tool
  • Focus: one-click, free, ad-free photo resizing
