DigiKam is the best free and open-source local photos manager, and it's not even close

Google Photos and Dropbox are good cloud-based options for photo and file storage and management, but using an open-source management toollike DigiKam is a better choice. Not only is DigiKam totally free — unlike the upgrades you’ll undoubtedly need with proprietary options — but its open-source development means you’ve got more control, privacy, and security options, too. Available on many platforms with many customization options, DigiKam should be your new photo manager of choice.
