Image Metadata

View image dimensions, file size, aspect ratio and format

What is it and how does it work?

An image metadata viewer reads a picture and shows you its core properties — pixel dimensions, file size, aspect ratio, format and orientation — without opening a heavyweight editor. These are the facts you need constantly: whether an image is large enough for a layout, too heavy for a page, the right shape for a frame, or in the format a platform accepts. Dragging in a file and seeing the numbers is faster than digging through an operating system's file properties or a photo app.

Knowing the dimensions and file size up front saves a lot of guesswork. Dimensions tell you if a photo will look sharp or pixelated at the size you need; file size flags an image that will slow a page down; aspect ratio tells you whether it will fit a 16:9 banner or a square avatar without awkward cropping; and the format (JPEG, PNG, WebP) determines transparency support and compression behaviour. This tool reads everything in your browser, so the image is never uploaded and even private photos stay on your device.

Common use cases

• Checking if an image fits: read the dimensions and aspect ratio to see whether a photo suits a banner, thumbnail or avatar.
• Diagnosing a slow page: check the file size to spot an image that is too heavy and needs compressing.
• Confirming the format: verify whether an image is JPEG, PNG or WebP before uploading it where a specific format is required.

Frequently asked questions

What is the difference between dimensions and file size?

Dimensions are the image's width and height in pixels, which determine how large and sharp it appears. File size is how many bytes it takes up, which affects download speed. A small-dimension image can still have a large file size, and vice versa, so both matter for different reasons.

Why does aspect ratio matter?

Aspect ratio is the proportion of width to height, and it determines whether an image fits a target shape without cropping or distortion. A 16:9 photo fits a widescreen banner but not a square avatar, so checking the ratio first avoids awkward crops later.

Does it read EXIF data like camera settings?

This viewer focuses on the core technical properties — dimensions, size, format, aspect ratio and orientation. Some images also carry EXIF metadata (camera model, GPS, date), which is separate; whether it is shown depends on the tool, and note that EXIF can include location data worth being aware of.

Is my image uploaded to read its metadata?

No. The properties are read entirely in your browser, so the image never leaves your device. You can safely inspect private or confidential photos without anything being sent to a server.
