How do you edit a post after publishing, and what are good edit practices?

Editing a post after it has been published is possible on Reddit for both the title (with restrictions) and the body text. The important constraint is that post titles cannot be edited after submission — only the body text of a text post can be changed. If your title contains an error, the only remedy is to delete the post and resubmit with the corrected title, which means losing any votes and comments already accumulated. To edit the body of a post on desktop, open the post and click the three-dot menu beneath the content area, then select Edit. This opens the text editor with the current body pre-loaded for modification. On mobile, the same process is available via the post's overflow menu. After making changes, saving creates an updated version, but Reddit does not automatically indicate that a post has been edited the way some other platforms do — though sophisticated readers may notice if they read the post previously. Good edit practices center on transparency and additive improvement. The clearest good-faith edit is adding information that was missing when you posted: a correction of a factual error, a relevant update that has occurred since you posted, or a clarification of a point that comments revealed was ambiguous. These additions should generally be flagged explicitly with a note like "Edit:" or "Update:" so readers who already engaged with the post understand what was added. Editing should not be used to quietly alter the substance of a post in response to criticism. If your original position drew pushback and you change it silently, people who already commented in good faith in response to the original post are left with replies that appear to argue against something the post no longer says. This erodes trust. If you genuinely changed your mind, acknowledging the change explicitly and thanking the person who persuaded you is the honest approach. For corrections to factual errors, noting the original claim and the correction together — rather than just replacing the text — is more transparent.
