Frequently Asked Questions
What is FIT file?
The FIT (Flexible and Interoperable Data Transfer) format is a compact binary file format developed by Garmin for recording, storing, and sharing fitness and activity data. It is commonly used by Garmin devices such as sports watches, bike computers, and fitness trackers to log information like GPS position, speed, heart rate, cadence, and elevation. FIT files are designed to be efficient, reliable, and easily extensible, allowing developers to include custom data fields. Users typically encounter FIT files when uploading activities to platforms such as Garmin Connect, Strava, TrainingPeaks, or other fitness analysis applications that support the format.
What is KMZ file?
The KMZ (Keyhole Markup Zip) format is a compressed version of KML, used to efficiently store and share geospatial data. A KMZ file is essentially a ZIP archive that contains one main KML file along with any related resources, such as images, icons, textures, or 3D models. This packaging makes KMZ ideal for distributing complete map visualizations that include both geographic features and their supporting media. KMZ files are widely supported in Google Earth, Google Maps, and various GIS applications, where they can be opened directly to display all included data in a single, self-contained file.
What is the maximum allowed size of input data?
The maximum size of the uploaded file is 5 GB. If your file is larger, you can try to compress it into a ZIP file with the maximum compression level (9) or, even better, into a 7z file. The contents of the package will be automatically unpacked on the server.
How secure is my data?
All data transfers are performed using the encrypted SSL protocol, which ensures secure data transfer. Both uploaded and converted data is temporarily stored in the data center and is further processed according to the user’s request. After some time, the data is automatically deleted - there is no need to delete it manually.
