Split a large ADIF log into valid, size-limited files — the original header is copied into each one. Everything happens in your browser; nothing is uploaded.
1. Load a log
Drop an .adi / .adif file here, or click to choose
2. Split settings
1 MB = 1,000,000 bytes, so 1.98 MB stays safely under a 2 MB limit. Records are never cut in half, and the original header is copied into every file.
