Fit vs Fill for Product Photos

Choose the detail to protect

Choose Fit when the entire photograph must remain visible. The empty part of the output receives a background color. Choose Fill when covering the whole output is more important than retaining the source edges. Inspect exactly what is removed before accepting it.

A photograph and the product inside it have different boundaries. Fit preserves the source rectangle, including any empty background already in that rectangle. It does not find a cup handle, remove a background or equalize the apparent sizes of different products.

Read the worked example

The source photograph below is portrait-shaped. Fitting it to a square preserves its top and bottom and introduces white side margins. Filling the square removes some of the background above and below the cup. In this particular composition, the cropped area is mostly background; a taller product in the same source frame could lose an important detail.

The exported pixels, rather than the names of the settings, settle the comparison. Download both square results and open them at the same display size. Compare the cup rim, base, painted decoration and surrounding background. Changing the composition can change which mode is appropriate.

Repeat in any image editor

Use an editor with a canvas or crop control. Keep a copy of the original. A resize control alone may only change dimensions while preserving the original ratio; it may not create a square canvas at all.

1. Set the destination canvas, for example 800 × 800 pixels, and preserve the source proportions.
2. For Fit, scale until the entire source fits inside the canvas and choose the background deliberately.
3. For Fill, scale until the canvas is covered, then position the crop around the details that must survive.
4. Export each variation separately from the original. Open the saved files and compare them side by side.
5. Inspect the final marketplace draft as well, because the destination can apply another crop.

When neither mode works

If Fit makes the product too small, inspect the empty space in the original before increasing the output resolution. A tighter source composition can help more than a larger canvas. If Fill removes a handle, accessory or quantity-defining piece, reposition the crop or retain the complete frame.

When a small source is enlarged, extra pixels do not restore a blurred label. Image Prep leaves enlargement off by default. Its margin applies to Fit, and Fill uses the chosen crop position. The reference example enables enlargement so both modes can cover the requested square; match that choice when reproducing it.
