Cut a distance from the start and end of each track before you share. Same format in, same format out — this page does not convert.
Supports GPX, TCX, KML, KMZ, GeoJSON, and CSV. FIT is not supported here (we cannot write FIT). Multiple files are trimmed separately.
Trim only — hide start & end, same format in and out. No conversion.

Hide home before you share
Cut the leave-home and return segments before publishing a route.
Same format in, same format out
GPX stays GPX — this page does not convert formats.
Many files, trimmed separately
Drop several files; each is trimmed on its own, then downloaded together.
FIT needs a convert first
We cannot write FIT — convert FIT → GPX, then trim.
Please noteTrimmed points are deleted from the export. This is not full anonymization.
FAQ
Are my files uploaded?
No. Trimming runs entirely in your browser.
Does this change the file format?
No. Same format in, same format out.
Can I trim FIT?
We cannot write FIT. Convert to GPX (or another writable format) first.
Is this full anonymization?
No. Only start/end points near your radii are removed; the middle may still show habitual routes.
