Screenshots that fit Instagram, not just fill it
Instagram crops wide images into awkward strips. Snapgloss places your screenshot on a 4:5, square or 9:16 canvas with a gradient around it, so the whole thing shows.
Set it once.
Post all week.
“Open with these settings” loads all of this into the editor, and the editor remembers it.
Three things
that make it work.
4:5 for the feed, 9:16 for stories
Portrait 4:5 is the tallest shape the feed shows uncropped. Use 9:16 for stories and Reels covers.
Phone screenshots look best with no frame
A window frame on a phone capture looks odd. Turn the frame off and raise the corner radius so it looks like a device screen.
Leave room for text
Bump padding up if you plan to add a caption on top in Instagram's editor — the gradient gives you a clean area to write on.
Questions,
answered.
What size should an Instagram post be?
Portrait 4:5 (for example 1080×1350) uses the most space in the feed. Square 1:1 and 9:16 for stories are also built in.
Can I use a phone screenshot?
Yes — any PNG, JPG or WebP works, including tall phone captures.
Is it really private?
Yes. Nothing is uploaded; the image is drawn on a canvas in your own browser.
