Download Parameter (dl)

Make your images downloadable with a simple URL parameter

Overview

The dl parameter allows you to control whether an image is displayed in the browser or downloaded automatically. When enabled, the browser will prompt the user to download the image instead of displaying it.

Usage

Add ?dl=1 to any HCTI.io image URL to make it downloadable:

https://hcti.io/v1/image/7cb776c5-8c12-4b1a-84aa-9941b815d873.jpg?dl=1

Implementation Examples

HTML Download Link

Create a download button or link:

<a href="https://hcti.io/v1/image/7cb776c5-8c12-4b1a-84aa-9941b815d873.jpg?dl=1" 
   class="download-button">
  Download Image
</a>

JavaScript Download Trigger

Programmatically trigger a download:

function downloadImage(imageId) {
  const downloadUrl = `https://hcti.io/v1/image/${imageId}?dl=1`;
  window.location.href = downloadUrl;
}

Common Use Cases

Creating downloadable certificates or badges
Offering high-resolution versions of images
Generating downloadable reports or charts
Providing image assets for users

File Format Tip

The dl parameter works with all supported formats (jpg, png, webp). The downloaded file will maintain the extension specified in the URL.
