About Instagram unfollower checker
Compare Instagram followers and following from an official data-download ZIP — entirely in your browser, no login.
Most 'who unfollowed me' sites want your Instagram password or a sketchy OAuth scrape. That is how accounts get locked. Instagram already lets you download your data as JSON inside a ZIP. This page reads that ZIP locally, compares followers to following, and lists people who do not follow you back.
Request your data from Instagram’s official privacy/download flow, choose JSON, wait for their email, then drop the ZIP here. Nothing is uploaded to our servers. If the export layout changes, the parser may need an update — trust official exports only, never a third-party 'login with Instagram' helper.
Caption formatter and character counters help with posts; they do not touch your graph. Archive unzip is a generic ZIP tool if you only need to inspect files.

Common questions
Do you need my Instagram password?
Never. Official ZIP export only. Any site asking you to log in for unfollow checks is a different — and riskier — product.
Is my followers list uploaded?
No. The ZIP is read in the browser with client-side unzip. Close the tab when you are done.
Why doesn’t this connect to Instagram’s API?
Live API access would need tokens and trust. The download-your-data path keeps credentials with Instagram and computation on your machine.

Why this one doesn't upload your file
There is no server to upload to. This page is a static file, and the work happens in your browser using the same graphics and WebAssembly code that renders every other site you visit. Your file is read from disk into memory, processed, and handed back as a download. Once the page has loaded you can disconnect from the network entirely and it keeps working. The longer explanation
