FAQ

Image ⇄ Base64 And Text ⇄ Base64 Converter FAQ

Frequently asked questions about converting images to Base64 and vice versa.

Base64 is a method of encoding binary image data into ASCII text using 64 characters (A-Z, a-z, 0-9, +, /). It's used to embed images directly in HTML, CSS, or JSON files, eliminating the need for separate image file requests and reducing HTTP requests.

We support all common image formats including PNG, JPG/JPEG, GIF, SVG, WebP, BMP, and TIFF. The original format is preserved in the Base64 output with proper MIME type declarations for web compatibility.

There’s no strict limit, but very large images may slow conversion; small to medium files work best. Can I convert Base64 strings back to image files?

Yes, simply paste the Base64 string into the tool and decode it to preview or download the image.

Advantages: embeds images inline, reduces HTTP requests, works offline; disadvantages: increases file size and is not ideal for large images.

Yes, conversion happens in your browser, keeping data private; using small images inline has minimal impact on SEO.

Yes, the generated Base64 strings are fully compatible with tags, CSS backgrounds, and JS strings for web projects.
