Why would GPS coordinates be in a photo?+−
Most smartphones tag photos with location data by default, using GPS along with Wi-Fi and cell tower positioning. It's genuinely useful for organizing your own photo library by place, but it also means a photo you post online can reveal exactly where you were standing - your home, your child's school, wherever - unless you strip it first.
Does removing metadata affect the photo's visual quality?+−
No. This tool only removes metadata from the JPEG file structure - the Exif segment, camera-maker blocks and any location fields in XMP - and doesn't touch, re-encode, or re-compress the actual image data at all, so the picture itself is pixel-for-pixel identical.
Do social media sites and messaging apps already strip this automatically?+−
Many do, but not all of them, and not always completely - policies change over time and vary by platform. If you're emailing a photo directly, uploading it somewhere that doesn't explicitly strip metadata, or just want to be certain, removing it yourself beforehand is the only way to know for sure.
Why does this only work with JPEG files?+−
Exif is a metadata format defined as part of the JPEG and TIFF standards, and it's stored inside a JPEG file in a well-defined, universally supported way. Other formats like PNG or WebP use entirely different metadata containers, so supporting them properly would need separate parsing logic.
Could stripping the metadata make my photo display sideways or upside down?+−
It's possible with some photos. Many cameras and phones - especially phones held vertically - save the actual pixel data unrotated and instead store an Exif Orientation tag that tells viewers how to rotate or flip the image for correct display. Since this tool removes the entire Exif segment, that tag goes with it, so if your particular viewer relies on it rather than an already-baked-in rotation, the stripped photo could appear in the wrong orientation.
Does this also remove the small preview thumbnail some photos have?+−
Yes. Many cameras and phones embed a small JPEG thumbnail directly inside the Exif data, used for quick previews in file browsers and photo apps. Because this tool deletes the whole Exif segment rather than editing individual tags, that embedded thumbnail - which is a real image and could show the same scene or even a different crop - is removed along with everything else.
Why does it say the GPS fields are empty when my phone saves locations?+−
On Android, when a browser (or any app without permission to read photo locations) opens a photo, the system hands over a copy with the GPS values blanked out but the empty fields still in place. That copy doesn't reveal where you were, but the original in your gallery still does - and apps that are allowed to read photo locations, or sharing a file straight from your file manager, can pass it on. If the tool shows real coordinates, the location really is in the file you picked.
