PNG size and transparency: a quick check

Start with the pixel dimensions

Before importing an image, compare its pixel dimensions with the space it must fill. A file's dimensions describe its raster grid. Its byte size describes how much storage the encoded file occupies. These are different measurements; a small file is not automatically a small image.

1. Open the image information or properties view in a tool that reports pixel width and height.
2. Write down the source dimensions and the dimensions your composition requires.
3. Preview the image at its intended display size before choosing it for the project.

Check opacity rather than guessing from the background

PNG supports transparency, but a PNG file does not have to be transparent. A white-looking preview on a white webpage does not tell you whether the image will cover a colored layer. Place the image over a contrasting background in your editor, keeping the image layer at full opacity. If the image covers that background, its light area is image content rather than a transparent opening.

Match the file to the task

Choose an image because its properties fit the task. If your composition needs a solid fill, a transparent spacer, or editable shapes, use a resource that actually supplies those properties. A minimal appearance alone does not make different file types interchangeable.

Keep the source and check the exported result

• Keep an unchanged source copy so repeated edits do not replace the original.
• Check the final exported dimensions after resizing or cropping.
• Open the exported image over the background where it will be used.
• Review the product's selected use terms before incorporating the file into a project.

Absolutely Nothing is currently a coming-soon product. Its listing is useful as a factual example, but ordering and file delivery are not open. The checks in this guide also apply to a PNG you already have permission to use.
