Free EXIF Viewer – Reveal the Hidden Data in Your Photos

What Is EXIF Data and How Does the EXIF Viewer Read It

Every JPEG your camera or phone saves quietly stores EXIF metadata alongside the visible image: which camera or phone took it, the lens focal length and aperture, the shutter speed, ISO sensitivity, the exact date and time down to the second, and often the precise GPS coordinates where the shot was taken. Most people never see this data, yet it travels with the file every time you email, message, or post it. A recruiter receiving your headshot could read your home address from the GPS tag; a stranger downloading your vacation photo could pinpoint the hotel. This tool parses the JPEG's embedded APP1/EXIF segment right in your browser and shows every field in plain language, so you know exactly what the file carries before you share it. Photographers, privacy-conscious users, forensic analysts verifying image origins, and developers debugging camera integrations all use it. Technically, the viewer reads the raw file bytes with the FileReader API, locates the EXIF marker at the start of the JPEG bitstream, and decodes the TIFF-structured IFD (Image File Directory) entries that follow it. It extracts the most useful tags: Make, Model, DateTime, DateTimeOriginal, ImageWidth, ImageLength, Orientation, ExposureTime, FNumber, ISOSpeedRatings, FocalLength, and the GPS IFD sub-block containing GPSLatitude, GPSLongitude, and GPSAltitude. The decoded values are presented in a readable table — for instance, shutter speed as "1/250s" rather than a raw rational pair. Because parsing is pure JavaScript running locally, nothing is uploaded; the tool never contacts a server. This is the one tool in the set that deliberately avoids the canvas: drawing an image onto a canvas hands back raw pixel values and throws the metadata away, so reading EXIF requires walking the actual file bytes instead. That distinction explains a lot of behaviour people find puzzling elsewhere — resize a photo, crop it, or convert it in almost any browser tool and the EXIF vanishes, because the pixels made the trip and the metadata did not. It also explains why GPS coordinates are stored as three rational number pairs for degrees, minutes, and seconds plus a separate reference tag for N/S and E/W, which the viewer converts into the decimal figure you can paste into a map. Here is a concrete example. You upload a 3.8 MB JPEG from an iPhone 15 Pro. The viewer instantly reports: Camera Apple iPhone 15 Pro, Date 2025-06-14 09:32:17, Dimensions 4032×3024, Focal Length 6.86 mm (equivalent ~24 mm), Aperture f/1.78, Shutter 1/1250s, ISO 50, and GPS 28.6139°N 77.2090°E — which in this case pinpoints a location in central Delhi. Seeing that GPS tag before you post the image lets you decide whether to strip it or accept it. If you upload a screenshot instead, the viewer reports "No EXIF data found" because screenshots rarely embed metadata. The day-to-day uses are focused on two things: privacy checking and information gathering. On the privacy side, people check whether a photo contains GPS data before posting it to social media, forums, or classified listings, since location information can expose a home address or workplace. On the information side, photographers review which settings produced a good shot so they can replicate or learn from it. Forensic teams verify the claimed origin of an image by checking whether the camera model and date match the story. Developers building camera-related apps confirm that metadata is being written correctly. And anyone receiving a photo from an unknown source can check whether it contains consistent metadata or has been stripped, which can be a rough authenticity signal. A few things to keep in mind. Social media platforms like Instagram, Facebook, and Twitter strip EXIF data on upload for privacy, so an image downloaded from those platforms will show nothing here — that is expected behaviour, not an error. PNG and WebP files rarely carry standard EXIF either, so JPEG is the format that gives the richest results. The viewer is strictly read-only: it never modifies your file. If you discover sensitive metadata and want to remove it, use a dedicated EXIF stripping tool before sharing. Your photo never leaves your browser — nothing is uploaded, nothing is stored, and the file bytes are released from memory as soon as you close the tab, so even checking GPS data on a private photo is completely safe.
