See everything hiding inside an image.
Upload a file or inspect a direct image URL to reveal dimensions, format, EXIF camera data, GPS tags, colour information, raw metadata and practical web-readiness checks in one clean report.
Inspect an image
Paste a direct image URL for the fastest workflow, or upload a file from your device.
Inspect from image URL
Paste any direct image link to check dimensions, file type, metadata and web-readiness.
Links are fetched by our server, because a browser is not allowed to read the bytes of another site's image. That is what makes every tag readable from a URL — the file itself is never stored.

Two Routes In, And They See Different Amounts
A file you drop in is read with the browser's own arrayBuffer, parsed here in the page and never sent anywhere — which matters, because the tags this tool exposes include the coordinates of where a photo was taken. A pasted URL is different: browsers deliberately refuse to hand JavaScript the bytes of an image from another site, so a link inspected purely in the browser could be measured but not read. That is why the URL box fetches through our server instead, which returns the file same-origin so the EXIF, GPS and colour parsing all work. The fetch is validated against private and reserved addresses first, capped in size, and the bytes are streamed straight back rather than stored. If you would rather nothing left your machine at all, download the image and drop it in the panel on the left — that route makes no request of any kind.

Image Metadata FAQ
What is image metadata, and what is EXIF?
Metadata is everything a picture carries besides the picture: how big it is, what format it uses, how many colours it holds. EXIF is one particular block of it, written by cameras and phones, recording the settings a shot was taken with — aperture, shutter speed, ISO, lens, the exact moment, and on most phones the GPS coordinates too. This page reads both, plus a sampled palette and a set of checks about whether the file is fit to publish.
Do my images get uploaded anywhere?
A file you drop in or browse to is not uploaded. It is read in the page with the browser's own file APIs and parsed here, which you can confirm in your network panel while you use it. A URL you paste is the exception, and it has to be: browsers block JavaScript from reading another site's image bytes, so that one request is made by our server, which streams the file back and keeps nothing.
Why does my photo show no camera or GPS tags?
Almost always because something stripped them. Every major social network and messaging app removes EXIF on upload, and so do most content management systems and image optimisers. Screenshots and images exported from design tools never had camera tags to begin with. A low score on the tag meter is normal for anything that has been through a platform — it is the camera originals that come back nearly complete.
Can this show me where a photo was taken?
If the GPS tags survived, yes — latitude, longitude and altitude appear in the Location card. That is worth knowing in both directions: it is useful when you are checking your own files, and it is exactly why you should strip metadata before publishing photos taken at home. If the card is empty, the coordinates were either never written or already removed.
What does the web readiness score actually measure?
Four things you can judge from the file alone: whether it is wide enough for large previews and responsive variants, whether the pixel area is reasonable, whether the format is one browsers handle efficiently, and whether the file weight is sane for delivery. It is not an SEO ranking. It is a sanity check on the source image before you put it on a page — a 12 MB camera original is a fine source and a poor thing to serve.
Which formats can it read?
Anything your browser can display is measured, so JPEG, PNG, WebP, AVIF and GIF all give dimensions, ratio, colour sampling and the web checks. Full EXIF parsing is JPEG, which is where camera and GPS tags actually live; PNG files additionally report their real bit depth and colour type from the header. SVG has no pixel metadata to read, so it will report size and little else.
