Strip location data from photos
Every photo a phone takes records the coordinates it was taken at, along with the device, the lens and the timestamp. For a picture of your living room posted to a forum, that is your home address travelling with the image.
Converting an image here removes it. Not as an option you have to find — as an unavoidable consequence of how the conversion works.

Worth knowing
- Why it cannot survive
- The image is decoded to raw pixels and re-encoded from those pixels. EXIF is a block of tags attached alongside the image data, not part of it, so there is nowhere for it to go. Converting a JPEG to a JPEG is enough — the format need not change. It is also why the result is the same whether the Strip metadata box is ticked or not: that switch is for audio and video tags, where ffmpeg can be told either way.
- Uploading to a stripping service defeats the purpose
- Every other free EXIF remover works by receiving your photograph, and the coordinates arrive with it. Whatever their policy says, the data was transmitted. Here it is not: this page has no server to send it to.
- Orientation is preserved, which is the one tag you want
- EXIF also stores which way up the camera was held. That is applied to the pixels before the tags are discarded, so the photo comes out the right way round rather than sideways — a mistake plenty of strippers make.
