If you want to disable emojis in WordPress, start with a narrower question: do you want to remove the emoji scripts, or stop people using emoji in your content? Those are different jobs. SlimPress is for switching off core features your site does not use, including WordPress's emoji scripts. It is not a content-moderation tool.
I built SlimPress around that distinction: choose a feature, read what the switch changes, and keep a way back. Here is how I would approach the emoji setting without pretending it is a shortcut to a fast website.
What the emoji switch actually targets
The SlimPress readme lists emoji scripts in its Front-end group. That is the scope of this change: WordPress's emoji-related scripts, not a promise to remove every emoji character or every script added by another plugin.
If your aim is to prevent emoji in comments, product reviews or submitted text, this is not the setting to reach for. Removing scripts and deciding what content visitors may submit are separate tasks. I would define the outcome first rather than switch something off because a cleanup checklist says so.
Is it worth doing?
I would treat this as a small, testable cleanup, not a headline performance fix. SlimPress gives its switches impact badges, including a cleanup-only rating where that is appropriate. That is a better starting point than assuming every removed feature must produce a noticeable improvement.
I am not attaching a loading-time saving, request count or before-and-after score to this article. I have not run a performance test on your site, and the readme does not establish a universal saving for the emoji switch. A cleaner page and a meaningfully faster page are not automatically the same result.
If performance is the reason for the change, measure your own pages. If consistency of presentation matters more, check that first. Keeping a feature is a valid outcome when the benefit of removing it is unclear.
How to disable emoji scripts with SlimPress
- Install and activate SlimPress from WordPress.org. Nothing is switched off until you choose a switch.
- Open Settings → SlimPress and go to the Front-end group.
- Find the emoji-script setting. Read its explanation, impact badge and what-might-break note before changing it.
- Enable that setting and save. Leave unrelated switches alone for this first check.
- Review the pages and workflows where emoji matter to your site before deciding to keep the change.
I would not apply a whole preset just to remove emoji scripts. Presets are useful when you intend to review several features, but changing one thing makes the result easier to understand and undo.
What to check before keeping it
The point of this review is not to assume that an emoji-related change is invisible. Use content you already have, and compare the result with the setting off and on. If you are unsure, use a staging copy rather than making the live site your first experiment.
- Existing content: inspect posts and pages that actually contain emoji, rather than only the homepage.
- Important shop pages: if emoji appear in product descriptions or other customer-facing text, check those specific places.
- The browsers you support: review the same content on the devices that matter to your audience.
- Other emoji features: test any plugin-provided picker or display feature separately. Do not assume a core switch controls another plugin's implementation.
These are checks to perform, not claims that I have tested your theme or plugins. SlimPress provides warnings when an active plugin relies on something you are about to disable, but I would still review the actual result.
Use the built-in test, not a borrowed benchmark
SlimPress includes a performance test that compares your own pages with and without its features in the same run, without changing your settings. The readme also describes individual-feature measurements and a breakdown of what plugins, the theme and core add to a page.
Use that when you want evidence for your decision. Keep other changes out of the comparison, choose representative pages, and read the result rather than looking only for a green score. If the test says within noise, I would not turn that into a speed-up claim. It means the difference is too small to treat as reliable.
What can break, and how to undo it
Read the emoji switch's own warning and check the presentation you rely on. If the result is not acceptable, turn that switch off again and save. For this runtime change, deactivating SlimPress also restores WordPress's default behaviour on the next request.
SlimPress keeps earlier versions of its settings, so a save can also be undone through its settings history. This is not a reason to experiment with unrelated retention or media settings: the readme explicitly warns that deleting data or omitting generated image copies is not reversed by deactivation. Keep this change limited to emoji scripts.
When another approach is better
If another plugin already manages the same feature, I would use one place to control it rather than add overlapping settings. If you only need this one change and already maintain a small custom plugin, that may suit your workflow better than a broader settings interface.
And if your actual problem is page caching, minification, delayed JavaScript or per-page script management, SlimPress deliberately does not do those jobs. Removing emoji scripts is not a replacement for investigating the problem you really have.
The short version: change one setting, check the result, measure any claimed benefit, and keep the undo simple. SlimPress is free, with no pro tier or telemetry; the plugin page explains the wider scope.
