Image Info Viewer

See the key facts about an image — dimensions, format, file size and more — without opening an editor.

The quick facts, at a glance

Before you use an image, you often just need to know a few things about it: how many pixels wide and tall it is, what format it is in, and how big the file is. Rather than open a heavy editor to check, drop it here and those details are read straight off the file. It is the fastest way to answer is this big enough, is it the right format, and why is this so heavy.

Handy when a form demands a minimum size, or when a page is loading slowly and you are hunting for the oversized image behind it.

Facts, not edits

This is a viewer, not an editor — its whole job is to tell you about the image, not change it. If the facts reveal a problem, that points you to the fix: too large in pixels calls for resizing, too heavy a file calls for compression, the wrong format calls for a conversion. Knowing the numbers first means you reach for the right tool.

How to check an image's details

  1. Add the image file.
  2. Read its dimensions, format, file size, aspect ratio and colour information.
  3. Use the details to decide what to fix.

Diagnose before you edit

Before resizing, compressing or uploading, it helps to know exactly what you are holding: the true pixel dimensions, the real format behind the file extension, the aspect ratio and the size on disk. Most upload rejections come down to one of those numbers being wrong.

It is also the quickest way to catch a mislabelled file — a picture saved as .jpg that is actually a PNG inside, which is a common reason a strict upload form refuses it.

Common questions

Why does a site reject my image even though it looks fine?

Usually the dimensions, the file size or the actual format fails their rule — checking the details first shows which.

What is aspect ratio?

The proportion of width to height, such as 16:9 or 1:1, which decides how the image fits a given frame.

Is the file uploaded to inspect it?

No. Everything is read in your browser.

What details does it show?

The pixel dimensions, the file format and the file size — the facts you usually need before using or uploading an image.

Does it change my image?

No. It only reads and reports the details; the file is left exactly as it is.

Is my image uploaded?

No. The details are read in your browser and nothing is sent anywhere.
