A good portrait crop feels deliberate. Before choosing it, decide whether the picture is about a face, an expression, clothing, or the person in a setting. A tight headshot needs a different frame from a full-length portrait. Cutting at an awkward joint or shaving a little off the top of the hair can look accidental even when the image is sharp.
Our preset exports 1080×1350 pixels, a 4:5 portrait. It crops a differently shaped source to fill that rectangle. Position the crop around the person and inspect the whole outline, including hands or shoulders that may sit near an edge. If keeping more vertical space matters, compare the existing 3:4 tool using the same original.
Use a focused, high quality source. If the face occupies only a tiny part of a large group image, a tight crop may not leave enough pixels for a clear portrait. A larger output file cannot rebuild eyelashes or skin texture that are absent from the source. The tool does not retouch skin, remove objects, change lighting, or repair missed focus. Complete those editing decisions before creating the publishing copy.
