Image Metadata Viewer online
See the basic facts of an image file — name, type, size in bytes, pixel dimensions and the file's own modified date — read locally, without uploading the picture anywhere.
How to use this tool
- Choose an image file. No upload happens; the browser reads the file on your device.
- Read the reported facts: file name, MIME type, size, dimensions and last-modified time.
- Compare files, or sanity-check an image before sending or publishing it.
Common uses
Verifying an image meets a slot's dimension requirements before upload, checking which of two similar files is the high-resolution original, confirming a "photo" is really the size a client claims, and quick file triage while organising a folder of assets.
How it works
The viewer reports what the file system and the decoded image know: the file's name and type, its size in bytes, its pixel dimensions once decoded, and the modification date your device recorded for the file. It is worth being precise about what is not here: this viewer does not dig into embedded EXIF (camera model, exposure, GPS) — the facts shown are the file's outer facts, not a camera roll's diary. That keeps the tool instant and dependency-free, and the "modified" date is the file's, which any copy or edit updates — it is not the day the photo was taken.
Worked example
Two files sit in a folder: banner.jpg at 1,240,118 bytes, 2400 × 1256, and banner-final.jpg at 212,540 bytes, 1200 × 628. The viewer settles in seconds which one is the full-resolution master and which is the web-sized export — the question "which file do I upload?" answered without opening an editor or uploading anything to a stranger's server.
Privacy and browser processing
Your image file is read locally by your browser — it is never uploaded or stored.
Frequently asked questions
Does it show EXIF data like camera and GPS?
No. This viewer reports file-level facts (name, type, size, dimensions, file modified date). Embedded EXIF — camera settings, capture time, GPS — needs a dedicated EXIF reader; stripping tools and photo apps on your device usually show it.
Is the "modified" date when the photo was taken?
Not necessarily. It is the last time the file itself was written — copying, downloading or editing a photo updates it. A photo taken in 2019 and copied today shows today's date. The capture date lives in EXIF, which this tool does not read.
Why do the dimensions differ from what a site requested?
Usually because the file is a retina (@2x) asset — twice the slot size on purpose, for sharpness on high-density screens. The slot wants 1200 × 628 of CSS space; a 2400 × 1256 file is the deliberate double. Check the requirement's wording before "fixing" it.
Can it read any image format?
Any format your browser can decode for display — JPEG, PNG, WebP, GIF, AVIF in supporting browsers, SVG (whose dimensions are its viewport). A format the browser cannot render cannot report dimensions here.
Is my image uploaded to read its facts?
No — that is the point of the tool. The file is read by your browser locally; nothing is transmitted or stored.
