What to know before you start
Resize and compress together
Changing dimensions often reduces file size. You can also adjust quality or output format for a smaller final image.
Crop vs fit matters
LessMB currently resizes while preserving aspect ratio in the tool controls. For exact square output, start with a square crop before resizing.
