About this tool: Image ↔ Base64 Converter
Encode common browser image files locally as Data URLs or decode valid image Base64/Data URLs into previewable, downloadable images with sensible size limits.
The workflow is designed for common browser-supported image files, with a preview so you can inspect the result before downloading it.
Image ↔ Base64 Converter is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
FileReader creates a Data URL locally for encoding; decoding validates the Base64 payload before using the image Data URL for preview/download.
Practical example
A PNG file can be converted to a data:image/png;base64,… URL entirely in the browser.
