While small, this extra request adds up—especially alongside similar “micro-bloat” sources—and can contribute to slower sites. The author recommends removing the emoji script via a short functions.php snippet or a plugin, noting that users won’t see a visual change but the page will be slightly lighter and cleaner. The theme is: small, steady performance wins compound into a noticeably faster, more professional site. ## 📖 Main Content: The piece frames the emoji script as legacy overhead: introduced in 2015 for broad emoji compatibility, it’s now mostly redundant as modern browsers natively support emoji. The cost is not catastrophic, but it’s unnecessary—extra bytes, extra request, extra parsing. The article positions this as emblematic of performance discipline: systematically trimming low-value assets leads to meaningful improvements. It offers two removal paths: - Code: remove actions in functions.php to stop printing detection scripts and styles. - No-code: disable via popular performance/asset management plugins. The payoff is incremental yet real: fewer requests, smaller payloads, cleaner source, slight speed gains. The narrative encourages continual maintenance (“start small, finish strong”) as a practical philosophy of web performance. ### 🗒️ Notes - Problem framing - WordPress adds emoji scripts to every page by default. - Users often assume “no emoji usage” = “no emoji assets,” but the script loads regardless. - Performance debt often accrues from many small, seemingly harmless additions. - Background/context - Emoji compatibility script dates to 2015. - Modern browsers typically have native emoji support; the fallback rarely triggers now. - Despite diminished utility, the script still loads on all front-end views. - Why it matters - Each request contributes to blocking, bandwidth use, and main-thread work. - Compounded micro-bloat degrades user experience over time. - Removing unnecessary code aligns with performance budgets and best practices. - Solutions - Code snippet: - remove_action('wp_head','print_emoji_detection_script',7); - remove_action('wp_print_styles','print_emoji_styles'); - Plugins: - Perfmatters, Asset CleanUp, Disable Emojis - Toggle “disable emoji” option. - Outcome - No visible UI changes—users won’t notice visually. - Measurable improvements: fewer network calls, smaller HTML/JS, cleaner DOM. - Philosophy: incremental fixes compound for speed and polish. - Takeaway - “Unnecessary code has no business slowing down your site.” - Adopt ongoing, small improvements to maintain performance hygiene. ## 📖 References: - Progress Planner article: “Emoji scripts? They’re slowing down your site” by Iris Guelen - WordPress core hooks: print_emoji_detection_script, print_emoji_styles - Tools: Perfmatters, Asset CleanUp, Disable Emojis ## 🗣️ Paraphrase: 1) Original idea: WordPress loads an emoji script on every page, even when you don’t use emoji, adding small but cumulative performance overhead. Paraphrase: Even if you never insert an emoji, WordPress still ships a detection script to every front-end page. That extra request may be tiny, but combined with other “little” assets, it contributes to a heavier, slower site. 2) Original idea: The 2015-era emoji fallback is largely obsolete due to modern browser support; removing it is a low-risk optimization. Paraphrase: The emoji polyfill once solved a real compatibility gap, but today’s browsers mostly don’t need it. Disabling it is a safe, quick win that trims cost without changing how your pages look. ## 📰 Newsletter: This week in WordPress performance: tiny trims, big wins. Remember that 2015 emoji compatibility script? WordPress still loads wp-emoji-release.min.js on every page—even if you never use an emoji. Modern browsers now handle emoji natively, so that fallback is usually idle weight. Two fast fixes: drop these actions in functions.php to stop it loading, or toggle “Disable Emojis” in performance tools like Perfmatters or Asset CleanUp. Multiply this by a handful of similar tweaks and you’ll feel the difference: fewer requests, lighter pages, smoother UX. Also on deck: learning pathways for modern theme building, community highlights from contributor onboarding cohorts, and fresh plugins that keep your Core Web Vitals happy. Keep it friendly, keep it fast, and ship fewer bytes. Recommended read: “Emoji scripts? They’re slowing down your site” (Progress Planner). ## ✅ Action Items (Advocacy + OSPO alignment): Prompt for aligning articles with your role and goals: - Open-source advocacy: Emphasize how removing legacy polyfills reduces resource waste, aligning with sustainable, efficient open-web practices. - Contributor engagement: Use this as a case study in contributor workshops to explain technical debt, deprecations, and the process for proposing defaults changes in core. - Education: Develop a micro-lesson demonstrating before/after waterfall charts, showcasing measurable impact from disabling emojis. - OSPO trajectory: Frame this as policy guidance—establish performance budgets, default-off legacy scripts, and governance for deprecating low-value assets across org properties. - Transparency/inclusivity: Provide clear docs for non-developers (site owners) on no-code plugin options; include accessibility notes and rollback steps. - Community sustainability: Advocate for periodic audits of default assets and cross-team discussions on deprecations to reduce ecosystem-wide bloat. - On/off-stage messaging: Turn this into a talk segment on “micro-optimizations that compound,” with repo examples and reproducible tests. Deliverables: - Publish a guide with code and plugin pathways. - Create a contributor-friendly issue template for proposing default asset removals. - Record a short screencast measuring impact with Lighthouse/WebPageTest. - Draft an internal OSPO memo on “Legacy Asset Retirement Criteria.” ## 🧪 Hypotheses: - H1: Disabling WordPress emoji scripts reduces First Contentful Paint and Total Blocking Time on average for sites with minimal third-party scripts. - H2: On mobile 3G-like conditions, removing emoji scripts yields a more noticeable improvement in Time to Interactive than on broadband. - H3: For content sites with no emoji usage, users will not perceive visual regressions after disabling the script. ### 📊 Methodology: - Data sources: Lighthouse CI across sample WordPress sites; WebPageTest on mobile profiles; RUM via Boomerang/GA4 custom events; Core Web Vitals field data (CrUX). - Design: A/B toggling emoji script across matched pages; stratify by theme, plugin load, and device class; run 30+ iterations to stabilize variance. - Analysis: Compare medians and confidence intervals for FCP, LCP, TBT, CLS; u - Summary: WordPress loads emoji scripts by default, even when you don’t use emoji.

But if you’re using WordPress, chances are it’s quietly adding emoji scripts to every page of your site, whether you need them or not. You won’t see them in your content. But your visitors’ browsers still have to load them. Every. Single. Time. And while one small script may not seem like a big deal, it’s often the little things that add up to a slow and bloated site. #### **What is this emoji script anyway?** Back in 2015, WordPress added a feature to ensure emoji showed up correctly across all browsers. It worked by loading a file called `wp-emoji-release.min.js`. This script checks if your visitor’s browser supports emoji. If not, it swaps in fallback images. That might have made sense back then. But now? Most browsers have native emoji support. The fallback script rarely does anything helpful. Still, it loads on every front-end page by default. No matter your theme. No matter your content. Even if you never use an emoji. #### Why it matters more than it looks You might wonder, does one extra file really slow things down? Not by itself. But rarely is it just one file. Site speed issues creep in quietly. A plugin here. A widget there. A leftover setting you didn’t know existed. And before you realize it, your fast site starts feeling slow. This script is part of that pattern. It adds a request. It adds code. It adds a delay. It doesn’t help your visitor, but it still gets loaded every time. That’s why [Ravi recommends removing the unnecessary emoji scripts](https://progressplanner.com/ravi-recommends/remove-emoji-scripts/). Not because it’s dramatic, but because it’s unnecessary. And unnecessary code has no business slowing down your site! #### How to remove the emoji script There are two easy ways to do this. You can choose the one that fits your workflow. ##### Option 1: Add a small snippet to your theme Open your functions.php file and paste this in: `remove_action( 'wp_head', 'print_emoji_detection_script', 7 ); remove_action( 'wp_print_styles', 'print_emoji_styles' );` Done! The script is gone. ##### Option 2: Use a plugin If you’d rather avoid code, use a plugin like **[Perfmatters](https://perfmatters.io/)**, **[Asset CleanUp](https://wordpress.org/plugins/wp-asset-clean-up/)**, or **[Disable Emojis](https://wordpress.org/plugins/disable-emojis/)**. Just check the setting to disable emoji support and save. Either approach works. The result is the same: no more unnecessary emoji bloat. #### What happens next? Nothing visible. And that’s exactly the point. Your visitors won’t see a difference. But their browsers will load one less file. Your page will be slightly smaller. Your source code will be cleaner. It’s a small improvement. But a real one. And when you fix five or six of these small things, your site starts to feel different. Faster. Smoother. More professional. #### Start small, finish strong Site maintenance isn’t about one giant fix. It’s about steady, thoughtful changes that add up over time. Removing emoji scripts won’t earn you a gold star. But it will move you forward. It’s progress. And it’s the kind that sticks!, Emoji Scripts?
