How to land close to a 25MB target:
Custom Size is already set to 25. Adjust only if you need a different limit.
Longer clips may look softer at 25MB. Trim first if quality drops too much.
Keep the tab open — a refine pass may run to get closer to the target.
Preview the result size before downloading. Re-run with a lower target if needed.
Custom Size aims at a real MB number instead of trial-and-error quality presets.
