Base64 Encoder for TypeScript Developers

Quick Answer

DevToolHQ's base64 encoder works great alongside TypeScript. Use it to quickly base64 encode during development, then integrate the pattern into your TypeScript codebase using the code example below.

Use Cases in TypeScript

1.Encode file uploads to Base64 for storage
2.Embed images inline in TypeScript templates
3.Encode binary data for API transmission
4.Convert credentials for HTTP Basic Auth headers

TypeScript Code Example

TypeScript

// TypeScript (Node.js runtime)
function encodeBase64(input: string): string {
  return Buffer.from(input, 'utf8').toString('base64');
}

function decodeBase64(input: string): string {
  return Buffer.from(input, 'base64').toString('utf8');
}

// For Bun / Edge runtimes (no Buffer)
function encodeBase64Web(input: string): string {
  return btoa(unescape(encodeURIComponent(input)));
}

// Type-safe file encoding
import { readFileSync } from 'fs';
const fileBase64: string = readFileSync('./image.png').toString('base64');
