# Optimizing a shared project

## Overview

Vectary is a powerful web-based tool capable of producing high-quality, realistic 3D scenes. But since projects are rendered directly in the browser, optimization plays a critical role in ensuring smooth performance and fast load times across all devices.

This page outlines key recommendations to help improve scene performance and loading time.

## Why optimization matters

There are two main areas where optimization makes a big difference:

**1. Performance**

Just like in video games, real-time 3D scenes in Vectary can perform differently depending on the device. While many optimization tasks are handled automatically, some require manual tuning — especially if the scene needs to run smoothly on lower-end devices like mobile phones or older laptops. \ <br>

**2. Loading Time**

When embedding a scene into a website, fast loading is essential. Ideally, the scene should load within **2 to 3 seconds**.&#x20;

For the best results, try to keep the **embed size under 5MB**, with a hard maximum of **10MB**
{% endhint %}

## Performance check

* Always preview the scene on low-end devices to ensure accessibility for all users.\ <br>
* Use the **Preview mode** to test performance and loading — it includes a built-in performance analyzer - [performance-analyzer](https://help.vectary.com/documentation/sharing-exporting-embedding/performance-analyzer "mention")\ <br>
* Keep textures, polygon count, and effects optimized (see detailed recommendations below):\ <br>
