Image Dimensions & File Inspector

Check a JPEG, PNG, or WebP file's real decoded dimensions, size, megapixels, and aspect ratio — not an EXIF viewer.

Image (JPEG, PNG, or WebP)

What this tool does — and doesn't — read

This reads the file's size and its actual decoded pixel dimensions, and derives the megapixel count and simplified aspect ratio from those. It does not parse or display EXIF metadata (camera model, GPS location, capture date, etc.) — this is a dimensions and file-size inspector, not an EXIF viewer. Displayed dimensions reflect the image as your browser renders it, meaning JPEG EXIF orientation is already applied the same way it would be if you opened the photo normally.

Your image is processed locally in your browser — it is never uploaded anywhere.

Check a JPEG, PNG, or WebP file's actual decoded pixel dimensions, file size, megapixel count, and simplified aspect ratio — copyable as a plain-text summary.

How to use the Image Dimensions & File Inspector

Click the Image field and choose a JPEG, PNG, or WebP file from your device.
Wait for Reading… to finish; a preview appears next to the results.
Check Filename, Type, File size, Dimensions, Megapixels, and Aspect ratio.
Click Copy summary to copy all six values as plain text, one per line.

Example: Checking a 12 MP phone photo

Choose IMG_1234.jpg, a 2,850,000-byte photo taken in landscape at 4032×3024. The tool shows Type image/jpeg, File size 2.72 MiB, Dimensions 4032×3024px, Megapixels 12.19 MP, and Aspect ratio 4:3, and Copy summary copies those values as lines such as Dimensions: 4032×3024px.

Questions about the Image Dimensions & File Inspector

Why does my screen-size image show 683:384 instead of 16:9?: The aspect ratio is reduced exactly by the greatest common divisor, with no rounding to familiar ratios. 1920×1080 reduces to 16:9, but 1366×768 is not exactly 16:9, so it shows 683:384.
Why does a portrait photo show 3:4 when my camera says 4:3?: Dimensions are read after the browser applies the photo's orientation, so an upright portrait shot is reported as taller than it is wide, for example 3024×4032px and 3:4.
Can I inspect very large images?: Only up to 25 MiB and 25 megapixels, the same limits the site's other image tools use. A 48 MP photo is rejected with a message giving its dimensions and the 25 MP limit.
Why is the file size different from what my computer shows?: Sizes are shown in binary units (1 MiB is 1,048,576 bytes), while many systems show decimal megabytes. A 2,850,000-byte file is 2.85 MB in decimal but 2.72 MiB here.
