Every photo from a phone or camera carries a hidden record of how it was made. Sometimes you want that record: to check which lens and shutter speed produced a sharp shot, to confirm when a picture was really taken, or to see whether an image you are about to post gives away where you live. This viewer opens any JPG, PNG, WebP, HEIC, AVIF or TIFF file and lays its metadata out in readable form.
The file is read by your browser and nothing is sent anywhere, which matters when the photo is private and the whole point is to find out what it reveals.
What EXIF and the other metadata blocks contain
EXIF is the standard block cameras and phones write automatically. It records the make and model, the lens, aperture, shutter speed, ISO and focal length, the date and time from the device's clock, the orientation, and often the software that last saved the file. When location services are on, a GPS section adds latitude, longitude, altitude and sometimes the direction the camera was facing.
Other blocks may sit alongside it. XMP is an XML record written by Lightroom, Photoshop and many apps, with ratings, keywords and edit details. IPTC carries captions, credits and copyright notices used by news agencies and photographers. An ICC colour profile describes the colour space, such as Display P3 or Adobe RGB. PNG files add their own header with dimensions and bit depth.
Why people check photo metadata
Privacy check before sharing
Open a photo before posting it on a forum or sending it to a stranger. If the location banner appears, the file contains coordinates that point to where it was taken, often within a few metres.
Learning from your own shots
Photographers compare aperture, shutter speed, ISO and focal length across a set of images to understand why one came out sharp and another blurred, or which focal length they use most.
Verifying where an image came from
Journalists, moderators and buyers look at the capture date, the camera model and the editing software to judge whether a picture is an original, a re-saved copy or a screenshot. Missing metadata proves nothing on its own, but present metadata can be telling.
What the viewer reads and shows
The open-source exifr library reads the EXIF, GPS, interoperability and thumbnail directories, XMP, IPTC, the ICC profile, the JPEG JFIF header and the PNG header, without decoding the picture itself. Manufacturer-specific maker notes, where some cameras hide details such as shutter counts, are not decoded. The summary tiles show Camera with the lens, Settings such as f/2.8 · 1/250 s · ISO 200 · 35 mm, Taken as written by the camera's clock, and Dimensions with the colour profile name.
If the photo holds GPS coordinates, a highlighted panel shows them to five decimal places with the altitude, plus an Open map button. That button is only a link to OpenStreetMap: no map loads on this page, and nothing is contacted unless you click it. Below, All metadata lists every tag grouped into EXIF, GPS, XMP, IPTC, ICC colour profile and File format tables, which you can copy or download as JSON. For JPG, PNG and WebP files, the file panel also lists each metadata block found and its size in bytes.
Como usar esta ferramenta
- Drop a photo on the box above, click to choose one, or paste it from the clipboard.
- Read the summary tiles for camera, settings, date and dimensions.
- If a location panel appears, use Open map to see the spot on OpenStreetMap in a new tab.
- Scroll through All metadata, then press Copy JSON or download the JSON file to keep the full record.
- To clean the file, press Remove this metadata to go to the EXIF remover.
Limitations
- The viewer only reads metadata; it cannot edit or add tags. Use the EXIF remover to strip them.
- Maker notes are not decoded, so brand-specific details such as shutter count or focus points are not shown.
- Camera RAW formats, videos and GIF files are not supported, and HEIC or TIFF images may show no preview in some browsers, although their metadata is still listed.
- The capture time has no reliable time zone and is only as accurate as the device's clock. Very long text values are shortened in the table but kept in full in the JSON.
