Remove sensitive photo metadata from a sharing copy, not from your only original. First inspect what the file contains, decide what should remain, and verify the exported result. Some images include location or device information; others do not. An empty properties panel is not proof that every metadata format has been cleared.
Inspect more than one visible field
A photo can contain EXIF, IPTC, XMP or other information depending on its format and history. Metadata viewers may show only a subset. ExifTool documents displaying duplicate tags, their groups and short names to reveal information a simplified properties panel may hide. It also notes that GPS information can exist outside the EXIF GPS group.
Choose a removal method that supports the format
Use a metadata editor or export workflow appropriate to the actual file type. Keep a backup, remove the chosen tags and reopen the output for inspection. Do not apply a blanket delete-all operation to a production or archival file without understanding what orientation, color, credit or rights information might be needed.
Know the limits of browser conversion
Raster re-encoding can create a fresh image without copying the original EXIF fields, but not every export path is equivalent. SVG cleanup in ZipMyImages only removes comments and whitespace; other metadata can remain in the markup. Local processing avoids a converter upload, but does not certify that the final file has no identifying information.
Verify the file you actually share
Illustrative check: inspect the original and the export side by side with the same metadata viewer. Look for the location and identity tags you intended to remove, check that orientation and color still look right, then share that exact copy. Review the visible picture for addresses, reflections and screens as well. Removing tags cannot hide identifying details in the pixels or undo information already published elsewhere.
