Understand the numbers
Image dimensions, resolution, and file size explained
These measurements describe different parts of an image and should not be used interchangeably.
Dimensions are width x height
Pixel dimensions describe the image's digital canvas. A 1920 x 1080 image has 2,073,600 pixels regardless of its compressed file size.
File size measures storage
KB and MB describe how much space the file uses. Compression and format can make two images with identical dimensions have very different file sizes.
Aspect ratio describes shape
Ratios such as 16:9, 4:3, and 1:1 describe the relationship between width and height, which helps when checking crop and layout requirements.
Common questions
Image Size Finder FAQ
Answers about privacy, supported formats, dimensions, file size, and mobile use.
Are my images uploaded to a server?
No. The tool reads the selected image locally with browser APIs. The file does not leave your device.
Which image formats are supported?
The checker supports formats your browser can decode, including PNG, JPEG, WebP, GIF, AVIF, SVG, and BMP in modern browsers.
What is the difference between image dimensions and file size?
Dimensions are the width and height in pixels. File size is the storage used by the encoded file, shown in bytes, KB, or MB.
Can I use the image size checker on a phone?
Yes. It works in modern mobile browsers and can read an image selected from your photo library or files.
Does this tool show DPI or EXIF metadata?
This focused checker reports reliable browser-readable size and file properties. Embedded DPI, camera, GPS, and full EXIF fields are outside this version's scope.
