- The FAQ describes a malformed FIT file as a possible 14-byte header and CRC-16 checksum problem.
Field notes
The homepage lays out an upload, process, and export sequence for FIT, GPX, and TCX files. It lists several operations, including map-based cropping, merging split activities, format conversion, and a GPS privacy zone. Its FAQ gives a specific example of a malformed FIT file, attributing the problem to a 14-byte header or trailing CRC-16 checksum. Browser-only processing is a site claim, not independently verified by the supplied page evidence.
