Fill and crop never resamples here: it keeps original pixels and cuts. Pad keeps every pixel and adds area, labelled as added area in the receipt. Stretch keeps the width and resamples the height, so the picture’s proportions change by the percentage shown.

Limits

  • No content-aware fill: padding is a flat colour or a blurred copy of the photo, never invented scenery.
  • Stretch distorts faces and circles visibly beyond a few percent; prefer crop or pad for people.

Questions

How do I change the aspect ratio of a photo without stretching it?

Choose Fill and crop or Pad. Fill and crop keeps the largest part of the photo that has the new shape and cuts the rest, so nothing is distorted; Pad keeps the whole photo and adds bars (white, black or a blurred copy) to reach the shape. Only Stretch distorts, and the panel prints by how much.

Does changing the ratio make the picture smaller?

Not unless you ask. Each ratio opens at the photo's own scale: a crop keeps the original pixels, a pad adds area around them, and a stretch resamples only the height. Type a box size afterwards if you also need exact pixels.

Which part is cropped?

The centre is kept at first. Move the crop with the Across and Down sliders, and the shaded strips on the stage show what will be cut before you save.

Which ratio for Instagram, YouTube or a phone wallpaper?

1:1 for a square post, 4:5 for a portrait feed post, 16:9 for a video thumbnail or a slide, 9:16 for a story, a reel or a phone wallpaper, 3:2 for a standard 6 × 4 inch print.
