About TrackKit

TrackKit is a small set of tools for one job done well: working with route files without handing your location to a server.

Why we built it

Convert a GPX file online and you will find dozens of sites that do it — by uploading your file to their server, wrapping the result in ad clutter, and often nudging you toward a paid plan. The problem is what a route file is. It is a precise, timestamped record of where you go, and it almost always begins at your front door. Uploading that to a stranger's server to flip a file format is a bad trade.

So TrackKit does the work where it belongs: in your browser. Your file is read into memory with the File API, converted, and handed back as a download. Nothing is uploaded, nothing is stored, and there is no account to create. You can watch your browser's network panel and confirm that no request carries your data anywhere.

What TrackKit does

We focus on the text-based route formats where we can guarantee a correct result: GPX, TCX and KML. You can convert between them, export a GPX to CSV for analysis, merge several files into one, and simplify a bloated GPX down to a sensible size. Every tool shows you a stats card — distance, elevation, point count, a route thumbnail and an elevation profile — so you can see what you are working with before you download.

What we deliberately avoid

We do not offer FIT conversion. FIT is a binary format that is genuinely risky to parse correctly in a browser, and a subtly corrupted route file is worse than no file at all. If we can ever do it reliably, we will; until then we would rather do less and be trustworthy.

How the site is funded

TrackKit is free. It is supported by unobtrusive display advertising, not by charging for conversions or selling data — we never see your files, so there is nothing to sell. See our privacy policy for exactly how advertising works and what cookies are involved.
