Before uploading an image to a platform with specific size requirements, it helps to quickly confirm its exact pixel dimensions and file size rather than guessing based on how it looks on screen. This tool reads those details instantly.
Upload any image and see its exact width and height in pixels, a simplified aspect ratio (like 16:9 or 4:3), and the file size in a readable format, all without needing any image editing software.
It's useful for checking whether an image meets a platform's exact size requirements, verifying an export came out at the expected resolution, or quickly comparing several images' dimensions before choosing one.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.
Bookmark this page if you expect to use this tool regularly — it loads fast and behaves the same way every time, with no account needed.
This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this conversion or calculation often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from search result to working tool in a couple of seconds.
Frequently asked questions
How is the aspect ratio simplified?
The tool finds the greatest common divisor between width and height and divides both by it, producing the simplest whole-number ratio.
Does uploading the image send it anywhere?
No, the image is read locally in your browser using the File API — nothing is uploaded to a server.
