Removing metadata is not redacting pixels
Camera details, recorded location, dates, comments, and author fields live outside the main picture data. Removing them does not blur a face, hide a street sign, erase a watermark, or remove information visible in the image. The original remains unchanged on your device.
Preserve compressed pixels
The default method rewrites supported JPEG, PNG, or WebP containers without re-encoding the compressed picture data. It removes EXIF blocks, XMP, comments, and other nonessential metadata. If a display orientation is required, a new minimal EXIF block retains only that tag. Color profiles and supported color instructions are kept when the checkbox is enabled.
A PNG copy for complete EXIF removal
PNG-copy mode decodes the displayed image, applies its orientation through the browser, and creates a new PNG. It does not copy original EXIF or ICC profiles. This avoids retaining an orientation tag, but it rebuilds the pixel representation and browser color handling can change appearance. A PNG can also be much larger than a JPEG or WebP.
