Frequently Asked Questions
How accurate is it?
The binary search algorithm gets within a few KB of your target in most cases. Very small targets on large images may not be achievable.
Why can't I hit a very small size?
JPEG compression has limits. If the target is smaller than what is achievable at the lowest quality, the tool returns the smallest possible result.
