Where to store images in a React project?

Storing and handling images in React projects is a fundamental part of front-end development, but it is often treated as an afterthought. The way images are stored and served can have a direct impact on performance, scalability and long-term maintainability, particularly as applications grow in size and complexity.

React’s flexibility means there is no single “correct” approach. Instead, there are several valid options, each suited to different use cases. This blog explores the most common ways to store images in a React project and explains how to choose the right approach based on your application’s needs. For clarity, the examples assume a React application built with Vite, which is now a popular choice for modern JavaScript development.

Understanding React’s image storage options

In a typical React setup, there are four main ways to handle images. Each approach comes with trade-offs, and the best choice depends on factors such as image size, how often assets change, performance requirements and how closely images are tied to your components.

Understanding these options early helps teams avoid inconsistent patterns, unnecessary performance issues and technical debt.

Importing images from the src folder

One common approach is to store images inside the src directory, often within a dedicated assets folder, and import them directly into components using JavaScript import syntax. For example, an image can be imported and referenced just like a module.

When you import images this way, React’s build process treats them as part of the application bundle. This makes the images easy to manage alongside your components and ensures they are included automatically during builds.

This approach works particularly well for images that are tightly coupled to the UI, such as logos, icons and small graphics that are part of a component’s structure. Because the images live in the codebase, they are tracked by version control, which reduces the risk of missing files across environments.

However, importing many or very large images can increase bundle size and negatively affect initial load time. For that reason, this method is best suited to smaller projects or to static UI assets rather than large image collections.

Storing images in the public folder

Another option is to store images in the public folder. Files placed here are served directly by the web server and are accessible via a URL, bypassing the bundling process entirely. In a Vite-based project, images are typically referenced using import.meta.env.BASE_URL to ensure paths work correctly across environments.

Because these images are not bundled, this approach avoids increasing the bundle size and is well suited to larger files or large numbers of images. It is commonly used for assets such as background images, favicons or user-uploaded content that does not need to be imported into components.

The trade-off is that images in the public folder are less tightly integrated into the React component lifecycle. If images are not tracked consistently in version control, there is a greater risk of files becoming out of sync between environments.

Using external URLs and content delivery networks

For larger or more performance-sensitive applications, images are often stored outside the React project altogether. In this approach, images are hosted on external services such as cloud storage platforms or content delivery networks (CDNs), and components simply reference them via URLs.

This decouples image storage from application code and offers significant scalability benefits. CDNs optimise delivery by caching images closer to users, reducing latency and improving load times. There are also no practical limits on image volume, making this approach ideal for applications with large media libraries or dynamic content.

The main drawback is the added complexity. External services introduce dependencies that must be monitored and managed, and developers need to handle permissions, security and availability. Despite this, for many production-scale applications, external image hosting is the most robust and future-proof solution.

Base64 encoding

A less common option is to encode images as Base64 strings and embed them directly in code or stylesheets. This removes the need for separate image requests, as the image data is included inline.

While this can reduce the number of network requests, it significantly increases file size and quickly becomes difficult to manage. For most modern React applications, this approach is not recommended and should only be used in very specific scenarios, such as tiny icons or specialised use cases where eliminating requests is critical.

Common mistakes to avoid

Choosing where to store images is as much about consistency as it is about technical detail. Teams often run into problems when image strategies evolve without clear decisions or documentation. Some common pitfalls include:

• Storing all images in the public folder without considering performance or maintainability
• Mixing multiple storage approaches inconsistently across the same project
• Forgetting to optimise images before adding them to the application
• Using high-resolution images for small display sizes
• Spreading images across different locations without documenting the rationale

Avoiding these issues usually comes down to making a deliberate choice early on, documenting it for the team, and reviewing image usage as the application evolves.

Choosing the right approach for your project

There is no universal rule for where images should live in a React project. Smaller applications often benefit from the simplicity of importing images from the src folder, while larger or more complex systems may rely on the public folder or external services. Many real-world applications use a combination of approaches, applying each one where it makes the most sense.

What matters most is understanding the trade-offs and applying them consistently. A clear image strategy supports performance, simplifies collaboration and makes applications easier to maintain over time.
