using a library like FileSaver.js or a manual Blob URL. typescript
For better performance and reliability—especially in browsers like Safari or when dealing with larger files—it is recommended to convert the Base64 string into a before downloading. This method avoids potential memory issues and browser URL length limits. download base64 image angular
import { saveAs } from 'file-saver'; downloadBase64(base64Data: string, fileName: string) { const byteCharacters = atob(base64Data); const byteNumbers = new Array(byteCharacters.length); for (let i = 0; i < byteCharacters.length; i++) { byteNumbers[i] = byteCharacters.charCodeAt(i); } const byteArray = new Uint8Array(byteNumbers); const blob = new Blob([byteArray], { type: 'image/png' }); saveAs(blob, fileName); // Uses [FileSaver.js](https://npmjs.com) } Use code with caution. Critical Considerations Angular download base64 file data - Stack Overflow using a library like FileSaver
downloadImage(base64String: string, fileName: string) { // Ensure the string has the correct data URI prefix const source = `data:image/png;base64,${base64String}`; const link = document.createElement("a"); link.href = source; link.download = fileName; // Trigger the download and clean up link.click(); link.remove(); } Use code with caution. Advanced Method: Converting Base64 to a Blob Create a Uint8Array from the decoded data
to extract the MIME type and the raw string. Decode the string using atob() . Create a Uint8Array from the decoded data.
To download a Base64 image in Angular, the most reliable method involves creating a virtual anchor element and triggering a click event to initiate the browser's download process. Quick Implementation: Component Logic
