Common Mistakes That Slow Down Framer Sites (2026)

Harish Malhi

Founder of Goodspeed

Most slow Framer sites are not slow by design. They are slow because of a handful of small mistakes that pile up unnoticed, oversized images, too many animations, stray third-party scripts, until pages crawl and visitors leave.

A slow Framer site loses rankings and signups. Goodspeed engineers performance in from the first decision, the way we did for Wisk, whose cinematic site holds up under real traffic. We are a Framer Enterprise Expert with 50+ Framer sites shipped. See our work on the Framer developers page or book a free consultation.

It matters more than it sounds. Given that 53% of mobile users leave a page that takes longer than three seconds to load, every one of these mistakes is quietly costing you engagement and conversions.

This guide walks through the most common mistakes slowing Framer websites, what each one costs you, and how to fix it fast.

1. Oversized or Uncompressed Images

Large, unoptimised images are one of the biggest contributors to slow page load times. While high-resolution visuals enhance your design, failing to compress or properly format them can lead to longer load times and poor Largest Contentful Paint (LCP) scores.

1.1 Issue: High-Resolution Visuals Everywhere

Symptom: If your homepage takes several seconds to load, your images might be the culprit.

Why It Happens: Many Framer users upload 2K or 4K images directly into their sites, assuming higher quality equals a better experience. However, these massive files take longer to load, especially on mobile devices, where performance is already compromised.

Fix: Before uploading, always compress images using TinyPNG or convert them to WebP format, which reduces file sizes by up to 30% compared to PNG or JPG without sacrificing quality. Using WebP ensures your images load faster while maintaining visual clarity.

1.2 Mistake: Not Using Lazy Loading for Large Image Sections

Impact: When all images load at once, even those below the fold, your site forces users to download unnecessary assets upfront, slowing down the entire page.

Fix: Implement lazy loading in Framer, which delays off-screen images until a user scrolls to them. This technique significantly improves first paint times and reduces bandwidth usage, particularly for image-heavy pages.

2. Too Many (or Overly Complex) Animations

Framer allows for beautiful animations and interactions, but too much movement can overwhelm both your audience and your site’s performance. Poorly optimized animations consume CPU/GPU resources, leading to lag and stuttering, especially on mobile devices.

2.1 Layering Animations Without Performance Checks

Problem: You’ve added smooth scrolling effects, hover animations, and interactive transitions, but now your site feels slow and jittery, particularly on lower-end devices.

Solution: Use animations strategically. Avoid layering multiple transitions on the same elements and opt for GPU-accelerated animations like transform and opacity changes, which are faster than animating width or position. Always test new animations on real devices to check for smooth performance.

For more best practices on optimizing scripts and keeping animations lightweight, check out our Framer code optimization guide.

2.2 Long Page-Load Animations

Impact: A long intro animation might look impressive, but if visitors have to wait several seconds before they can interact with the page, they’ll likely leave.

Fix: Minimize entry animations so users see important content instantly. Keep effects subtle and lightweight, ensuring they enhance rather than hinder speed optimization and usability.

Working with a Framer agency can help you strike the right balance between dynamic design and high-speed performance.

3. Neglecting Mobile-First Layout Adjustments

Since mobile pages load 70.9% slower than desktop pages, neglecting mobile-specific optimisations can severely impact site speed and user experience.

3.1 Only Designing for Desktop Screens

Consequence: Large desktop layouts, oversized hero images, and wide margins create issues on smaller screens, increasing bounce rates.

Fix: Use Framer’s breakpoint features to create mobile-friendly layouts with smaller image sizes and streamlined sections. Test your site on multiple screen sizes using tools like PageSpeed Insights to ensure responsiveness and speed.

3.2 Large Fonts and Margins

Symptom: Jumbo-sized fonts and excessive white space inflate page size, leading to slower rendering speeds.

Fix: Use system fonts instead of heavy custom typefaces and limit the number of font variations. This reduces font load time and ensures faster rendering across all devices.

4. Excessive Third-Party Scripts or Embeds

Third-party scripts like chat widgets, analytics tools, and social media embeds can add valuable functionality, but excessive external requests can drastically slow down your Framer website. Each script introduces new dependencies, increasing server response times and rendering delays.

4.1 Embedding Multiple External Widgets

Examples: Chatbots, live chat pop-ups, multiple tracking scripts, or overlapping Google Analytics, Meta Pixel, and Hotjar.

Why It Slows Down: Each script sends requests to an external server, increasing the time it takes to fully load a page. If your site relies on too many scripts, it results in render-blocking elements, causing noticeable delays.

Fix:

Audit your third-party scripts and remove anything non-essential.
Use asynchronous loading so scripts don’t interfere with page rendering.
Consolidate analytics tools-if you’re using multiple platforms, determine if one tool can provide all the data you need.

Stat: 45.4% of users are less likely to purchase on slow sites, making speed a critical factor in conversions.

4.2 Heavy Video Embeds

Problem: You’ve embedded multiple high-resolution YouTube or Vimeo videos directly on your pages. This forces the browser to load external video players and autoplay scripts, delaying other content.

Fix: Instead of embedding full video players, use a static thumbnail with a “click-to-play” option. This ensures that the video only loads when a user interacts with it, significantly improving page speed.

5. Underusing Framer’s Built-In Hosting Optimization

Framer’s built-in hosting is designed to deliver high performance without external optimization tools, but many users fail to leverage these features properly.

5.1 Forgetting to Check Publishing Options

Mistake: Updating your design but failing to re-publish the site can leave outdated, cached versions visible to users. This can lead to discrepancies in performance and content visibility.

Fix:

Always re-publish your site after making significant changes.
Test performance using an incognito window to ensure you’re seeing the latest version.
Use Framer’s pre-rendering features, which optimize static content for faster delivery.

5.2 Skipping Framer Updates

Problem: Framer frequently rolls out performance enhancements, but many users don’t update their sites to take advantage of these improvements.

Fix:

Check Framer’s release notes regularly-some updates include automatic optimisations that improve Framer performance without manual effort.
Enable auto-updates when possible to ensure your site benefits from Framer’s latest speed and hosting improvements.

6. Lack of Ongoing Performance Checks

Speed optimization isn’t a one-time task. Many Framer users assume that once a site is optimized, it stays fast forever, but new content, features, and design changes can gradually slow it down.

6.1 Relying on "One-Time Optimization"

Trap: You optimize your images and animations once, assuming your Framer website will remain fast. However, adding new elements over time-like new product pages, blog sections, or embedded content-can cause performance to degrade.

Fix:

Run monthly performance audits using Google PageSpeed Insights or Framer’s built-in performance tools.
Track Core Web Vitals to see if your Largest Contentful Paint (LCP), First Input Delay (FID), or Cumulative Layout Shift (CLS) scores are declining over time.

For a step-by-step walkthrough, use our Framer performance audit guide to catch issues before they impact users.

Stat: Only 12% of mobile sites and 13% of desktop sites pass all three Core Web Vitals thresholds, making it essential to monitor and optimize performance continually.

6.2 Ignoring User Feedback

Clue: Visitors mention that pages feel slow, animations are lagging, or the site loads inconsistently.

Action:

Monitor real-world user behaviour with session replay tools like Hotjar.
Run performance tests on different networks and devices, especially mobile connections.

For more complex troubleshooting or technical support, consider working with our expert Framer developers to identify backend or script-level issues affecting speed.
