An EXIF viewer that keeps your photos private
Every photo from a camera or phone carries hidden information: which device took it, when, with which settings — and often exactly where. This EXIF viewer reads that metadata in your browser using the exifr library and presents it in grouped, readable tables. It is useful for photographers checking their settings, for journalists verifying images and for anyone who wants to know what a picture reveals before sharing it.
What the metadata groups contain
| Group | Typical content |
|---|---|
| Image (IFD0) | Make, model, orientation, resolution, software, modification date |
| EXIF | Exposure time, aperture (FNumber), ISO, focal length, lens, flash, date taken |
| GPS | Latitude, longitude, altitude, direction, timestamp |
| XMP | Editing history, ratings, keywords added by Lightroom or Photoshop |
| IPTC | Caption, author, copyright, credit line — common in press photos |
| ICC | The embedded colour profile, e.g. Display P3 or Adobe RGB |
Reading the summary
The summary translates raw tags into plain values: an ExposureTime of 0.004 becomes "1/250 s", and FNumber, ISO and FocalLength are combined into one exposure line such as 1/250 s · f/2.8 · ISO 200 · 35 mm. Dates are shown in ISO format. Note that EXIF dates usually have no time zone, so the time shown reflects the camera's clock setting.
Why GPS data matters
Phones write GPS coordinates into photos by default when location access is enabled for the camera. Posting such a photo — on a forum, marketplace or blog that does not strip metadata — can reveal your home address to strangers. When coordinates are present the viewer shows a prominent warning with the position and a link to OpenStreetMap, so you can see how precise it is. Remove the data with the EXIF remover before sharing.
When there is no metadata
Screenshots, images exported "for web" and pictures downloaded from social networks usually contain little or no EXIF, because those platforms strip it on upload. The viewer then tells you that no metadata was found. PNG files only carry text chunks and basic header fields, and HEIC photos can be read even if your browser cannot display them.
Exporting the data
Use Copy JSON or Download JSON to keep the full metadata for documentation or to compare two images. Binary fields such as thumbnails are summarised by their size. To inspect the pixels instead, the image color picker reads colours, and the image compressor re-encodes photos without metadata.
Photographers: learn from your settings
Comparing the exposure data of your best and worst shots is a quick way to learn. Check whether blurry photos were taken at slow shutter speeds, whether noisy ones used a very high ISO, and which focal lengths you actually use — useful when choosing your next lens.
Metadata also helps with support requests: when an image looks wrong in your app, its orientation, colour profile and dimensions are often the explanation.
Privacy
Everything happens locally in your browser with JavaScript and the Canvas API. Your images are never uploaded to our servers, so the tool also works with confidential screenshots and personal photos.
