Under 50 KB means a maximum
The output can be substantially smaller than 50 KB; it is not padded to exactly the limit. Fylqen chooses the highest-quality feasible result within its bounded optimizer.

When compression is not enough
If the original cannot meet the limit at the supported quality and resize bounds, the tool reports that clearly rather than producing an unverified file.
