What does the Image to Base64 Converter do?

The Image to Base64 Converter from PowerSEOTools.online lets you upload an image and instantly convert it to a Base64 encoded string. You can generate raw Base64, data URIs, tags and CSS snippets for embedding images directly in HTML or stylesheets.

Which image formats are supported?

You can upload common image formats including JPG, JPEG, PNG, GIF and WebP. The tool reads the image in your browser and converts it to a Base64 encoded data URI.

Are my images uploaded or stored on your server?

No. All conversion happens directly in your browser using JavaScript and FileReader. Your images are not uploaded, stored or logged on our servers, making this tool safe for private and client work.

When should I use Base64 images?

Base64 images are useful when you want to embed small icons, inline images or email-safe assets directly in HTML or CSS without separate HTTP requests. For large images or many assets, external image files are usually better for performance.

Can I generate HTML and CSS snippets from the Base64 output?

Yes. The tool can generate different output formats including raw Base64, a data URI, a ready-to-use tag and a CSS background-image snippet, so you can copy and paste them into your project.

The Image to Base64 Converter from PowerSEOTools.online lets you encode images as Base64 strings directly in your browser. This is especially useful when you want to embed small images directly into HTML, CSS or JSON without hosting separate files.

When to Use Base64 Images

Base64-encoded images are helpful in scenarios where you need everything bundled into a single file or where external image URLs are not practical:

HTML emails: Embed logos and icons directly so they are less likely to be blocked.
Single-file widgets or demos: Share a single HTML file that contains all assets inline.
JSON or config files: Store small icons as data URIs in settings or design tokens.
Prototyping: Quickly try out icons and images without managing file paths.

For large images and production websites, external image files with proper caching are usually better for performance than Base64.
