For JPEG files, this page checks a limited set of EXIF camera, date and GPS tags. A missing GPS result does not prove the file has no other metadata.
For JPEG files, this page checks a limited set of EXIF camera, date and GPS tags. A missing GPS result does not prove the file has no other metadata.
Your browser decodes the image and re-encodes it on a canvas. JPEG is saved as JPEG at quality 92; PNG is saved as PNG.
The original is not changed. Re-encoding removes the EXIF data handled by this workflow, but is not a forensic guarantee against every nonstandard metadata chunk.
EXIF is a camera-image metadata standard. See the Camera & Imaging Products Association standards and the browser canvas image export documentation.
JPEG and PNG files can carry information in addition to the visible image. Depending on the camera, phone settings and editing history, EXIF may include a camera make or model, capture time, exposure settings or GPS coordinates. GPS is optional: many photos have no location tag at all. The CIPA EXIF standard describes fields image software can store; it does not mean every field is present in every photo.
The browser decodes the image and writes a new raster copy. PNG stays PNG; JPEG stays JPEG and is re-encoded at quality 92, so a small quality change is possible. Image dimensions and visible orientation are retained where the browser decodes them correctly. Color profiles and other nonstandard metadata are not guaranteed to be preserved or removed in a particular way.
This page is an EXIF preview and copy maker, not a full forensic metadata auditor. Its preview reads a small group of JPEG EXIF tags. A “no GPS found” message means no GPS coordinates were recognized by this reader; it does not prove that every metadata format has been removed. It does not process video, PDF or HEIC files, alter the original, or recall a photo already shared elsewhere.
Photo reading and canvas re-encoding run in the browser. The page does not send photo bytes to an ECECH image-processing endpoint. This describes the tool workflow, not third-party page resources such as advertising scripts.
