Image Metadata Viewer

See an image's key facts — dimensions, file size, type, aspect ratio and megapixels — and download them as a text report. Note: it reads file properties, not embedded EXIF.

Quick Answer

Drop in an image and it shows the key facts: file name, type, size, pixel dimensions, aspect ratio, megapixels and the file's last-modified date. You can download them as a text report. One thing to know: it reads the file's properties, not the embedded EXIF — so it does not show camera settings or GPS location. Everything runs in your browser.

What the Image Metadata Viewer Does

This reads an image's basic file facts and lays them out: the dimensions in pixels, the file size, the type, the aspect ratio, the megapixel count, and when the file was last modified. You can save the lot as a text report.

It is worth being clear about what it does not do. Despite the name, it does not parse the EXIF metadata embedded by cameras — there are no aperture, shutter, ISO or GPS readings here. It reports the properties of the file, not the photographer's settings.

How It Works

Drop or pick an image. The browser reads its file properties and decodes it to measure the pixel dimensions.

From those it derives the aspect ratio (width divided by height) and the megapixels (width times height, divided by a million), and reads the file's size, type and last-modified date.

The facts are shown on screen, and a download saves them as image-metadata.txt. Nothing is uploaded.

Processing pipeline

  1. Read file properties. The browser reads the file's name, type, size and last-modified date — locally, never uploaded.
  2. Measure the pixels. The image is decoded to read its exact width and height in pixels.
  3. Derive the figures. Aspect ratio and megapixels are calculated from the dimensions.
  4. Show and export. The facts are displayed and can be downloaded as a text report.

Derived figures

Aspect ratio = width ÷ height Megapixels = (width × height) ÷ 1,000,000
Worked example
A 4000 × 3000 image: aspect ratio 1.333, and 12.00 megapixels.

These come from the pixel dimensions. The name, type, size and last-modified date are read straight from the file.

Privacy

Your image is inspected entirely in your browser and never uploaded — there is no server.

No account and no stored copy; the facts and the report stay on your device.

It only reads properties — it does not change your image in any way.

Standards & references

  • File properties — General facts about any file — name, type, size and last-modified date — read from the file system, distinct from data embedded inside the image.
  • EXIF (not read here) — EXIF is camera metadata embedded in a photo — aperture, shutter, ISO, date taken, GPS. This tool does not parse it; it reports file-level facts only.

Accuracy & Limitations

It reads file properties and pixel dimensions, not embedded metadata. So it shows accurate size and dimensions, but no camera settings, capture date or GPS — those live in the EXIF, which this tool does not parse.

The last-modified date is the file's timestamp from your device, not the date the photo was taken. They can differ if the file was copied, edited or re-saved.

Aspect ratio and megapixels are calculated from the pixel dimensions, rounded for readability. The dimensions themselves are exact.

It is read-only: it inspects the image and changes nothing. The download is a plain-text report of the facts shown.

Real-World Use Cases

Check dimensions quickly

See an image's exact pixel size and megapixels before using it.

Confirm file size and type

Check whether an image meets an upload's size or format limit.

Work out the aspect ratio

Read the aspect ratio to plan a crop or layout.

When to use it — and when not to

Good for

  • Checking dimensions, size, type and aspect ratio
  • A quick megapixel count
  • A downloadable record of the facts

Not the best choice for

  • Reading EXIF camera settings or GPS
  • Seeing the photo's capture date
  • Editing or removing metadata

To remove location and camera metadata, use the EXIF data remover; a dedicated EXIF reader is needed to view embedded camera and GPS data.

Frequently Asked Questions

Does it show EXIF data like camera and GPS?
No. Despite the name, it reports file-level facts — dimensions, size, type, aspect ratio, megapixels and the file's last-modified date. It does not parse the embedded EXIF, so there are no camera settings or GPS readings.
What is the difference between file properties and EXIF?
File properties are general facts about any file, like its name, size and modified date. EXIF is photographic metadata embedded inside a photo by the camera — aperture, ISO, date taken, GPS. EXIF is a subset of metadata; this tool reads the file-level facts, not EXIF.
Is the last-modified date when the photo was taken?
No. It is the file's timestamp on your device, which can change when the file is copied, edited or re-saved. The capture date lives in the EXIF, which this tool does not read.
What facts does it show?
File name, type, size, pixel dimensions, aspect ratio, megapixels and the file's last-modified date — and you can download them as a text report.
How is the megapixel count worked out?
It multiplies the width by the height and divides by a million. A 4000 by 3000 image is 12 million pixels, or 12.00 megapixels.
How is the aspect ratio calculated?
It divides the width by the height. A 4000 by 3000 image has an aspect ratio of about 1.333, which is the same as 4 to 3.
Does it change or upload my image?
Neither. It is read-only and runs entirely in your browser. Your image is inspected locally and never uploaded or altered.
What is in the downloaded report?
A plain-text file, image-metadata.txt, listing each fact on its own line, handy to keep as a record.
Why would I want to know the megapixels?
Megapixels indicate how much detail an image has, which matters for printing or large displays. A higher count can be cropped or printed bigger without looking soft.
Can it read any image format?
It reads the common web formats the browser can open. It reports their file facts and dimensions the same way.
How do I see the camera settings then?
You need a dedicated EXIF reader, which parses the embedded photographic tags. This tool focuses on the file-level facts instead.
Can I remove the metadata here?
No, this only views file facts. To strip embedded EXIF and GPS before sharing, use the EXIF data remover.
