Image Dimensions Inspector: instructions, examples and limits

What it does

Reads decoded pixel width and height, MIME format, byte size and aspect ratio.

Use the dimensions inspector when you need the exact pixel size, format, file size or aspect ratio before another image operation.

How to use it

1. 1

   Choose a still image from your device.

2. 2

   Read the decoded width, height, format, bytes and simplified aspect ratio.

3. 3

   Use the result to select a resize preset or document the asset’s original dimensions.

How the result is produced

Reads decoded pixel width and height, MIME format, byte size and aspect ratio.

Important limits

Pixel dimensions do not determine physical print size without a print resolution. JPG, PNG, WebP and browser-decodable AVIF inputs (named converters require their stated source format); 25 MB and 24 megapixels maximum. Output is a single still frame; animation, source colour profiles and metadata are not preserved.

Checks before sharing or relying on the result

• Pixel dimensions describe the digital image, not a guaranteed physical print size.
• Orientation metadata can affect how an image is displayed by other applications.
• The file is decoded locally and is not uploaded.

Choosing the next step

Use Resize when the dimensions are the problem, Compress when the bytes are the problem, and Metadata Remover when the file contains information you do not want to distribute. Format conversion is a separate choice: JPG is usually compact for photos, PNG keeps transparency, and WebP can be a useful modern compromise.
