Premiere Pro 2026 writes project version 45; Premiere Pro 2021 expects 39. Because Premiere Pro 2026 uses the newer, sparser project format, Backport first restores the fields older releases require (it rebuilds the structure of project version 42), then sets version 39.
Premiere Pro 2021 is several releases older. Effects introduced after it may not be available; if anything looks off, import the sequences from the converted project into a new Premiere Pro 2021 project.

Is the file uploaded anywhere?
No. The conversion runs in your browser and the result is downloaded straight to your computer.
What happens to effects that do not exist in the older release?
Effects and features added after Premiere Pro 2021 can be dropped or show as missing. Sequences, clips, in and out points, and media links are kept unchanged.
