Photos from a single post
A post with one picture gives you one JPG at the size Instagram stores it. Most people open an Instagram picture downloader for exactly this: one shot from someone's feed.
Save photos from public Instagram posts and carousels as JPG files
Yes, and for photos the free plan is the full version: the JPG is the same size on every plan, with no cap on how many you save. You can download Instagram photos free without signing up. Premium adds HD video, MP3 and faster downloads.
Yes, from public accounts, and you get a real file: the Save button inside Instagram only bookmarks the post in the app. The photo still belongs to its author: keep it for personal use and ask permission before you repost it or use it commercially.
No. Neither Instagram nor iGram notifies the author when a public photo is downloaded.
No. Public posts open without an Instagram account, and iGram never asks for your username or password.
iGram saves photos as JPG, the format Instagram delivers. If you need a PNG, open the JPG in Preview on a Mac or Paint on Windows and export it as PNG. Converting changes the format only and adds no detail.
No. iGram stores neither the links you paste nor the files you save. The details are in the privacy policy.
No. You can download Instagram pics in any browser on iPhone, Android, Windows and Mac, with nothing to install.
