EXIF & Metadata Viewer for Images and Videos
See the hidden metadata in any photo or video, camera model, shutter, aperture, ISO, capture date, and GPS location. Everything runs in your browser; the file is never uploaded. Free, no signup, sources cited below.

How it works
Every photo your camera or phone takes carries a block of EXIF (Exchangeable Image File Format) data written alongside the pixels. This tool opens that block and turns the raw tag values into readable numbers, without sending your file anywhere.
- Images. The file is parsed in your browser with
exifr, an open-source library that follows the CIPA/JEITA Exif specification. It extracts the TIFF/IFD0 tags (make, model, software), the EXIF sub-IFD (exposure settings), GPS, IPTC, and XMP blocks for JPEG, TIFF, PNG, WebP, HEIC, and AVIF files. - Exposure maths. Some cameras store settings as APEX values rather than friendly numbers. Shutter speed comes from
exposure time = 2^(−Tv)and aperture fromf-number = 2^(Av/2). When both the APEX value and the plain tag are present, the tool shows an "APEX cross-check ✓" so you know the two agree. - GPS. Coordinates are stored as degrees, minutes, and seconds with a hemisphere reference. The tool converts to signed decimal degrees with the direct formula
D + M/60 + S/3600and verifies it against a second method (total arc-seconds ÷ 3600). A Google Maps link and privacy warning appear when location is found. - Videos. MP4 and QuickTime files have no EXIF; instead a built-in scanner walks the ISO Base Media box tree to the
mvhdmovie header for the creation time and duration, and the©xyzatom for any ISO 6709 GPS string. QuickTime counts time in seconds from 1 January 1904, so the tool shifts by that epoch to get a normal date. The browser also decodes the resolution and duration directly.
The privacy scan flags three categories that identify you or where you were: GPS coordinates, device serial numbers, and owner/author names. These are exactly the tags worth removing before posting a photo publicly.
