Image Metadata Viewer

Image Metadata Viewer summarizes technical properties from image files, including dimensions, MIME type, file size, and embedded metadata where available. It is read-only and local.

Image Metadata Viewer Runs locally

Drop an image or click to browse

JPEG, PNG, WebP, GIF, BMP supported

Step by step

How to use it

Drag and drop an image onto the drop zone, or click it to browse and select a file.
The tool reads the image and displays file name, size, MIME type, dimensions, aspect ratio, and megapixels.
For JPEG files, it also attempts to extract a capture date and camera info from embedded EXIF data.
Click 'Copy as JSON' to copy all the extracted fields to your clipboard.

When to use it

Use cases

Quickly check an image's exact pixel dimensions and megapixel count before using it in a design or upload.
Verify a file's true MIME type when the file extension might be misleading.
Check the aspect ratio of an image against a required ratio (e.g. 16:9 or 1:1) before cropping.
Look up a JPEG's approximate capture date and camera info without a dedicated photo app.
Compare file size against dimensions to gauge compression quality before publishing an image.

Limits & privacy

What this tool does and does not do

Private by design

The image file is read and inspected entirely in your browser. It is never uploaded to a server.

EXIF-based date and camera extraction only works on JPEG files, and uses a lightweight scan rather than a full EXIF parser.
Does not extract GPS coordinates or the broader EXIF tag set (exposure, ISO, orientation) — see the EXIF Viewer tool for that.
Read-only — it inspects metadata but does not edit, strip, or re-save the image file.

Background

Reading the file's own structure

This inspects the file at byte level rather than asking the browser to decode the picture. A JPEG begins with a two-byte start-of-image marker and is then a chain of segments, each declaring its own length, and metadata lives in specific segments within that chain.

Walking the chain directly means the extension is irrelevant. A file named .jpg that is really a PNG is immediately visible, which is a common source of confusion when an upload is rejected for the wrong format despite an apparently correct filename.

It also means what you see is what the file contains, not what a viewer chose to show you. Metadata is routinely present and invisible in normal image viewers, which is exactly why files get shared with more information attached than the sender intended.

Questions

Frequently asked questions

Is Image Metadata Viewer free to use?

Yes. The tool is free and runs directly in your browser with no account required.

Does this tool upload my data?

No. The image is read and inspected locally using the browser's Image and FileReader APIs — it is never uploaded to a server.

What metadata does it show?

File name, file size, MIME type, pixel dimensions, aspect ratio, megapixels, and last-modified date for any image. For JPEG files, it also attempts to extract the capture date and camera info from embedded EXIF data.

How is this different from the EXIF Viewer tool?

This tool focuses on general file and dimension properties (size, MIME type, aspect ratio, megapixels) with a best-effort JPEG date/camera lookup, while the dedicated EXIF Viewer parses the full EXIF tag set (exposure, GPS, orientation) in more detail.

Why don't I see a capture date for my PNG or WebP file?

EXIF-style capture date extraction only runs on JPEG files here, since PNG and WebP don't typically embed EXIF metadata using the same structure.

Can I copy the metadata results?

Yes — click 'Copy as JSON' to copy all extracted fields as a JSON object, useful for pasting into documentation, bug reports, or a spreadsheet.

Does it read GPS location data?

This tool's EXIF extraction is a lightweight scan for date and camera fields specifically — it does not extract GPS coordinates. Use the EXIF Viewer tool if you need to check for embedded location data.
