Posting Canvas to Imgur
New here? Learn about Bountify and follow @bountify to get notified of new bounties! x

I've been banging my head on the documentation but must be missing something.

What I'm looking to do is take my fabricjs canvas, which I can already save as an image, and upload it as an image to

How I'd imagine it'd work: User draws/does something with the canvas > User clicks Send to Imgur button > Script would generate and upload that to Imgur.

Here's my little fiddle example:

Please let me know if I can provide any more info that'd help you with writing something.


can you provide an api?

Hello, I believe this is the right part of it, but I may be mistaken:

no i meant the userId (or clientId) that you have with imgur

Oh okay, so I may need to regenerate these as I only have the jsfiddle, not really any site for the callback yet: d460753dba2907b is my clientid

3 Solutions

Here is the most simple and sharper solution, ever created in the internet.

it just work like drinking tea!

project source:

demo is available here:

Unfortunately, i can't work on your fiddle for now to modify it as you require, the project code is super easy, hope you understand it and accept that.

if you didn't came to solve it by yourself, you can wait, i can deliver it (your fiddle modified) after +2Hours from now,

And a tip would be nice :)

I can definitely wait the 2 hours! I will play with this in the meantime. Thank you.

Here is a solution to upload an image to imgur.

var client_id = ""; // Your client Id
var access_token = ""; // Your access token
var image_url = "";// URL of the image to upload
var album_id = ""; // The album you are uploading to

 var form = new FormData();
 form.append("image", image_url); 
 form.append("album", album_id);
var xhttp = new XMLHttpRequest();"POST", "", true);

xhttp.setRequestHeader('Authorization', 'Client-ID '+client_id); 
xhttp.setRequestHeader('Authorization', 'Bearer  '+access_token); 

xhttp.onreadystatechange =async function () {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
        var res = JSON.parse(xhttp.responseText);

Try the above solution and let me know if you have any hitches...

The album_id is optional... unless you want to upload to a specific album

Check this solution is using my client testing id just adding an ajax request to do the uploading stuff. I just convert the data URL to base 64 (the image) and then post it to imgur using their api.

This is very close to what I'm after! Could you make it so that the Save simply saves the image to your local instead of the Send to IMGUR button being dependent on it? Will gladly tip.

Would you consider adding a multiplier to the image size for a tip? I've tried, but can't seem to get the image larger (so that it's a little more clear on IMGUR). Cheers

A multiplier? Could you give an example so i can try and implement it on the actual solution?
