Photos and videos are opened by your browser, edited on your device and saved straight back to it. Nothing is sent to Posty or anyone else, and re-saving a photo drops its location data.
Sized, captioned, then scheduled
Posty’s composer has the same editor built in. Crop once per network, write the caption, and schedule it to Instagram, Facebook, TikTok, LinkedIn, YouTube, Threads, Pinterest, Bluesky and Discord from one calendar.
