Get your hands on the base64 image by triggering the save as popup and downloading

I am facing a challenge with downloading a base64 image onto the user's machine.

So far, I have attempted the following steps:

var url = base64Image.replace(/^data:image\/[^;]+/, 'data:application/octet-stream');
window.open(url);

and

window.location.href = base64Image.replace('image/png', 'image/octet-stream');

While these methods do allow me to download the image to a specific location, I would like to give the user the ability to provide a file name as well. Something similar to the saveAs method. Any suggestions on how to achieve this?

Additionally, I am curious if there is a way to handle the ok/cancel buttons that appear in the save dialog.

Answer №1

It is not possible to achieve this task using JavaScript as it requires specific browser features to display dialogs.

If you are looking to assign a name to your base64 image, consider utilizing a library such as FileSaver.js.
