Why would I convert an image to Base64 instead of just linking to the file?

Base64 encoding embeds the image data directly inside your HTML, CSS, or JSON, which avoids a separate network request — useful for tiny icons, email templates, or offline-capable web apps.

Does Base64 encoding make the file larger?

Yes, Base64 encoding increases file size by roughly 33% compared to the original binary file, since it represents binary data using only text characters. It's best suited for small images, not large photos.

Can I convert the Base64 string back into an image file?

Yes, most image editing tools and browsers can decode a Base64 data URI back into a viewable or downloadable image; you can also paste it directly into an <img src=> tag to render it.

Is there a size limit for images I can convert here?

There's no hard limit set by the tool, but very large images produce very long Base64 strings that can be unwieldy to copy, paste, or embed — this method works best for icons, logos, and small graphics.
