Check image resolution, format and file size
Choose a JPG, PNG or WebP image to inspect its dimensions, aspect ratio and file details without uploading it. Compare the information with the requirements of the form or website you are using.
Example and important limitation
For example, check whether a photo is already 200 × 230 pixels before changing it. A file’s extension alone may not prove its encoded format; review the reported type.
