Ever updated a PDF and realized half your site links to the old version? Or replaced a hero image and watched your carefully-tuned page layout collapse? Smart Media Replacement solves both problems — and adds a safety net you’ll wish you had earlier.
Replace the file, keep the URL. When you swap an attachment with this plugin, the file’s URL never changes. Every existing link, every email that points to it, every page that embeds it, every SEO ranking — all of it keeps working. No 404s, no broken references, no scrambling to update old content.
Full revision history, one-click restore. Every replacement automatically snapshots the previous version. Made a mistake? Roll back instantly. Want to see what the file looked like three months ago? Download it. Each revision is timestamped, attributed to the user who made it, and can carry an optional note describing what changed.
Works where you work. Replace from the Media Library, or from inside any block’s Replace toolbar in the block editor — image, cover, video, audio, file, gallery, and more. The editor refreshes in place, no page reload, no lost work.
Safe by default. The plugin validates filenames, file types, and image dimensions to keep your URLs intact and your layouts unbroken. WordPress’s auto-scaled images are handled transparently. Revisions land in a database table that’s self-healing on every admin load, and the plugin’s settings page gives you control over how many revisions to keep, how long to retain them, and which file types are tracked.

Revision Diet is a plugin to limit the number of post revisions that are saved. It does exactly what you expect – it allows you to set a number of revisions to keep for each post and deletes any revisions beyond that number. This number will not include the autosave revisions.
The options page is extremely simple – enter the number of revisions to keep and save your options. There is also a button to ?Trim Excess Revisions.? This button will trim all the extra revisions from every post in your WordPress installation. (Using it is optional.) As for regular use, each time you save a post the oldest revisions on that post will be deleted from the database down to the limit that is currently set.
