How to strip EXIF data without wrecking your photo

Removing metadata sounds trivial — delete the EXIF block, done. In practice two things go wrong constantly: sideways photos and needless quality loss.

The orientation trap

Cameras usually save pixels in sensor orientation and record a rotation flag in EXIF. Your gallery reads the flag and shows the photo upright. Strip all metadata naively and the flag goes with it — every portrait displays rotated 90°. The fix: bake the rotation into the pixels first, then strip. Any scrubber that doesn't do this will eventually flip something you care about.

Lossless strip vs re-encode

There are two ways to clean a JPEG. A lossless strip rewrites the file without the metadata segments — pixels untouched, perfect quality, but vendor-specific blocks can slip through. A full re-encode repaints the image onto a clean canvas — guarantees nothing survives, at a small quality cost. A good tool offers both: lossless when you're only removing location, re-encode when you want certainty.

Don't forget the filename

IMG_20240613_154207.jpg leaks the capture date all by itself. Rename on export — a detail most tools skip.

The checklist

Bake orientation. Choose lossless or re-encode deliberately. Drop the embedded thumbnail. Rename the file. And verify with a viewer afterwards — trust the diff, not the button label. MetaMarshal shows that diff before you download, so you're never guessing.
