Image Quality and Fidelity

html2canvas:
html2canvas captures the visual representation of DOM elements, including their styles and images. However, the quality may vary depending on the complexity of the element and how well the library can render it. It is generally reliable for most use cases, but may not be as precise as the other two libraries in rendering certain styles.
html-to-image:
html-to-image also offers good image quality, with a focus on simplicity and ease of use. It handles SVG and canvas elements well, ensuring that the generated images are clear and visually appealing.
dom-to-image:
dom-to-image provides high-quality image generation by rendering DOM elements accurately, including SVGs, text, and styles. It preserves the visual fidelity of the elements, making it suitable for applications where image quality is important.

Customization Options

html2canvas:
html2canvas provides some customization options, such as setting the background color and excluding certain elements from the capture. However, it is more focused on capturing the element as it is, rather than providing extensive customization features.
html-to-image:
html-to-image offers basic customization options, such as setting the background color and image format. It is designed to be straightforward and easy to use, with minimal configuration required.
dom-to-image:
dom-to-image allows for significant customization, including setting background colors, adjusting image dimensions, and handling cross-origin images. It provides a flexible API that lets developers fine-tune the image generation process according to their needs.

Cross-Origin Support

html2canvas:
html2canvas supports cross-origin images, but it requires the images to be served with CORS headers to avoid tainting the canvas. If the images do not have the proper CORS configuration, they will not be rendered in the canvas, which can affect the quality of the captured image.
html-to-image:
html-to-image also supports cross-origin images, but similar to dom-to-image, it requires the images to have the correct CORS headers. This ensures that the images can be accessed and rendered without any security issues.
dom-to-image:
dom-to-image has good support for cross-origin images, provided that the images have the appropriate CORS headers. It handles cross-origin images gracefully, allowing them to be included in the generated images as long as they are served from a CORS-enabled server.

Ease of Use: Code Examples

html2canvas:

html2canvas is widely used and has a large community, which makes it easy to find resources and support. Its API is straightforward, but understanding how it captures elements may require some reading. Example:

import html2canvas from 'html2canvas';

const element = document.getElementById('my-element');
html2canvas(element)
  .then((canvas) => {
    document.body.appendChild(canvas);
    const img = canvas.toDataURL();
    console.log(img);
  })
  .catch((error) => console.error('Error capturing element:', error));

html-to-image:

html-to-image is designed to be user-friendly, with a modern API that makes it easy to convert HTML elements to images. The documentation is clear and provides examples. Example:

import { toPng } from 'html-to-image';
import { saveAs } from 'file-saver';

const node = document.getElementById('my-node');
toPng(node)
  .then((dataUrl) => {
    const img = new Image();
    img.src = dataUrl;
    document.body.appendChild(img);
  })
  .catch((error) => console.error('Error generating image:', error));

dom-to-image:

dom-to-image is relatively easy to use, with a simple API for converting DOM nodes to images. It requires minimal setup and provides clear documentation. Example:

import domtoimage from 'dom-to-image';
import { saveAs } from 'file-saver';

const node = document.getElementById('my-node');
domtoimage.toPng(node)
  .then((dataUrl) => {
    const img = new Image();
    img.src = dataUrl;
    document.body.appendChild(img);
  })
  .catch((error) => console.error('Error generating image:', error));
