((free)) Download Image Base64 Nodejs Instant
For a zero-dependency approach, use Node's native https module to collect data chunks into a buffer.
Axios is a popular choice for this task because it simplifies handling binary data with the responseType property. javascript download image base64 nodejs
const axios = require('axios'); async function downloadImageAsBase64(url) { try { // Fetch image as an 'arraybuffer' to handle binary data const response = await axios.get(url, { responseType: 'arraybuffer' }); // Convert the buffer to a Base64 string const base64 = Buffer.from(response.data, 'binary').toString('base64'); // Optional: Prepend the data URI header for use in HTML tags const mimeType = response.headers['content-type']; return `data:${mimeType};base64,${base64}`; } catch (error) { console.error('Error downloading image:', error); } } Use code with caution. For a zero-dependency approach, use Node's native https
This ensures the data is received as raw bytes rather than being corrupted as a UTF-8 string. This ensures the data is received as raw
: Check the Axios documentation for advanced request configurations. 2. Using Built-in https Module
To download an image and convert it to Base64 in Node.js , you primarily fetch the image as a binary buffer and then encode that buffer into a string using Node's built-in class . This technique is essential for embedding images directly into JSON responses, HTML data URIs, or text-based databases. Core Methods to Download and Encode 1. Using Axios (Recommended)
