Diff

Diff Code Screenshot Generator

Turn Diff snippets into images worth sharing, without leaving your Mac.

Diffs are the single best argument for sharing code as an image: the green and red carry the meaning, and both are lost the moment it becomes plain text.

Codeshot detects Diff from the code you paste, so there is no language picker to get wrong. Here is the same snippet in three of the 30 themes it ships with, rendered with the app's own stylesheets.

Choosing a theme for Diff

Do not trim the hunk header. The line numbers are what tell people where in the file they are looking.

Getting the size right

Let the image follow your content, or lock it to a ratio — 1:1, 4:3, 3:2, 16:9, 9:16, 2:3, or 3:4 — then export at 1×, 2×, or 3× so it stays sharp on a retina display. Copy it straight to the clipboard with ⌘⇧C, or save with ⌘S.
