How it compresses
The number you set is a hard ceiling, not a goal. FITFILE probes the image at different quality levels, measuring the real output each time, and keeps the highest quality under your limit — reducing resolution only when quality alone can't get there, and always telling you when it did. If a limit genuinely can't be met at a usable resolution, it says so instead of pretending. After compressing you can keep working on the same image — resize it, enlarge it, or run it again with a different limit — without re-uploading.
