EXIF is the block of data a camera or phone writes into every photo. See each EXIF field in your photo, remove the private ones, and keep the settings needed to display it.
The tool runs in your browser (JavaScript required). Nothing is uploaded.
EXIF stores dozens of fields. Some are private, some are purely technical. This tool shows both, with their real values, and treats them differently.
JPEG keeps EXIF in its own segment; HEIC and AVIF keep it as an item inside the file; PNG and WebP use an EXIF chunk. JPEG and HEIC files keep the technical fields after cleaning. In PNG and WebP the technical fields sit in the same chunk as the private ones, so they are removed with it — the result says so.
EXIF is one kind of metadata, written by cameras and phones. Photos can also carry XMP, IPTC or text metadata from editing apps. This tool checks all of those, not just EXIF.
They describe how the picture was taken, not who took it or where. They are shown to you as technical information and kept so the file stays complete.
Yes. The orientation value is kept so the photo displays the right way up.
Yes. The new copy is reopened and its EXIF is read again. A field only gets a check mark if that second read no longer finds it.
