How to Upload Images without Metadata
Question I've heard that image metadata can store your personal info. If I edit a picture in photoshop or paint, then save it, will it have my PC and gps data in it? Suggested advice It is suggested that for jpg use guetzli, and for png use zopflipng. They all help you get the absolutely smallest image possible by brute forcing combinations of internal encoding parameters; it also strips absolutely all the meta data in the process. No metadata will be left, use some hex editor to verify they won't even know what software you used at all. Although photoshop saves a lot of nasty crap, never post any pics without going through guetzli or zopflipng. Leave a comment if you have alternative suggestions or recommendations.
