A picture of a newly painted room may reveal more than the colour of the walls. Before sharing it publicly, check both the file and the scene. You do not need to reorganise your entire photo library to make a considered choice about one image.
Decide which copy will leave your phone
Start with the intended use: a public listing, a family album or an attachment to one person. Keep the original if its location helps you organise memories. Prepare a separate sharing copy when you need different information to travel with it.
On iPhone, Apple documents a sharing option in Photos: open Share, then Options, and turn Location off. This concerns that sharing action; removing location from an existing photo and preventing future camera geotags are separate choices.
Check the route as well as the setting
Google Photos warns that location-sharing controls inside its service do not govern a downloaded file emailed elsewhere: original camera location can remain. Do not assume that hiding an album’s location also cleans every exported copy.
Try your intended route with a harmless sample. Save the resulting attachment, inspect its information and check whether coordinates are present. Inspect the delivered file, not just the original thumbnail. An absent map in one viewer is a limited check, rather than proof that every kind of metadata has gone.
Read the photograph itself
Imagine a room photo with an envelope on a table, a building number through the window and a reflection in a mirror. Decide which details belong in your public picture. Retaking it against a simpler background may be easier than editing several small areas.
Make the final check after all edits and exports. Confirm that you are attaching the reviewed copy, then keep that copy clearly named. This avoids doing the careful work correctly and sending the original by mistake.
