100KB shows up constantly on exam registration portals, government job application forms, and university admission systems as the maximum size for a photo or scanned document. It’s tight enough to keep servers fast, but usually still leaves enough room for a clear, recognizable photo.
If your source photo is very large or highly detailed, KBKaro will reduce its dimensions slightly as well as its quality to reliably land under 100KB.
