Is there any way to copy image to clipboard with pure javascript without libraries? - Stack Overflow

I've tried using document.execCommand('copy') like this site but it didn't work (nothing got copied to my clipboard despite the fact that the console.log said it was successful). I also used the navigator.clipboard API but that didn't work for my jpg images, and here is its code:

navigator.clipboard.write(
[
    new ClipboardItem({
        'image/jpeg': new Blob( ['media/anime_0.jpg'],{type:'image/jpeg'} )
    })
])
.then(e=>{console.log('Copied to clipboard')})
.catch(e=>{console.log(e)})

The above code produces the following error:

DOMException: Sanitized MIME type image/jpeg not supported on write.

Anyone know if I'm doing anything wrong or if it's even possible to copy images to clipboard without using external libraries?

• Pretty sure the Blob should actually have the raw image data - potentially as loaded in via Fetch API - and not just a URL. – Niet the Dark Absol Commented Jul 15, 2020 at 7:24
• Could you specify what you mean by "raw image data"? Would base64 / Uint8array forms of an image be considered raw image data? – user8380672 Commented Jul 15, 2020 at 7:30

Thanks Keith for the link to: convert image into blob using javascript

This is the solution I used for my app (it will only save images as png, as jpeg/jpg files keep giving me the DOMException error.

const img = new Image
const c = document.createElement('canvas')
const ctx = c.getContext('2d')

function setCanvasImage(path,func){
    img.onload = function(){
        c.width = this.naturalWidth
        c.height = this.naturalHeight
        ctx.drawImage(this,0,0)
        c.toBlob(blob=>{
            func(blob)
        },'image/png')
    }
    img.src = path
}

setCanvasImage('media/anime_0.jpg',(imgBlob)=>{
    console.log('doing it!')
    navigator.clipboard.write(
        [
            new ClipboardItem({'image/png': imgBlob})
        ]
    )
    .then(e=>{console.log('Image copied to clipboard')})
    .catch(e=>{console.log(e)})
})

I know the above answer has been accepted, but nonetheless, this is my version in Vue 3 SFC using ant design

<template>
  <Card title="Copy Image" size="small" class="my-card">
    <img :src="imageSrc" alt="Non Coi Male" />
    <Button size="small" type="dashed" @click="copyImageToClipboard(imageSrc)"
    >Copy</Button>
  </Card>
</template>
<script setup lang="ts">
import { Card, message, Button } from 'ant-design-vue';

const imageSrc = 'https://some-image-url/mockimage.jpeg';

const copyImageToClipboard= async (src: string) => {
  const covertedPngImage = new Image();
  covertedPngImage.src = src;
  covertedPngImage.onload = () => {
    const canvas = document.createElement('canvas');
    const ctx = canvas.getContext('2d');
    canvas.width = covertedPngImage.width;
    canvas.height = covertedPngImage.height;
    ctx?.drawImage(covertedPngImage, 0, 0);
    canvas.toBlob((blob) => {
      if (blob) {
        const item = new ClipboardItem({ 'image/png': blob });
        navigator.clipboard.write([item]);
        message.success('Copied image to clipboard');
      } else {
        message.error('Failed to copy image to clipboard');
      }
    })
  }
}
</script>
