It is fairly small. Small photos and scans usually fit at good quality; a full-size phone photo goes down to the tool’s lowest quality setting and is then made smaller, so expect it to look soft up close.

What to expect

50KB is the most common limit on application forms, and it is a far more forgiving target than it sounds. A passport-style headshot at 413x531 pixels fits inside it comfortably with quality to spare, which is not a coincidence — the limit and the photo size were designed for each other.

For a full scene rather than a headshot, the tool may have to shrink the picture as well as lower the quality. If the destination is a display rather than a form, one of the larger targets will serve you better.

Scanned paperwork behaves differently from photographs at this size. Text stays crisp at 50KB far more readily than faces do, because sharp black-on-white edges survive compression better than skin tones and gradients. If a scan comes back muddy, it is usually resolution rather than quality that needs raising.
