To make a button on your Webflow website download a PDF file without redirecting the user or opening a new tab, you can follow these steps:
1. First, upload your PDF file to your Webflow project. You can do this by going to the Webflow Designer and navigating to the Assets panel. Click on the "Upload" button and select your PDF file from your local machine. Once uploaded, you can find the PDF file in the Assets panel.
2. Next, you need to set up a custom code on the button. Add a button element to your Webflow page or use an existing button. Select the button and click on the "Settings" tab in the right-hand panel.
3. In the "Settings" panel, you'll find the "Link Settings" section. Here, you need to switch the link to a custom link. To do this, click on the dropdown menu next to "Link Settings" and choose "Custom URL."
4. Now, you need to create a custom URL that triggers the PDF download. To do this, use the format: `/#pdf-url.pdf`. Replace `pdf-url` with the name of your uploaded PDF file, without the file extension. For example, if your PDF file is named "my-document.pdf," the custom URL will be `/#my-document.pdf`. Make sure to include the slash (/) at the beginning of the URL.
5. After setting up the custom URL, click outside the settings panel to save your changes.
Now, when a user clicks on the button, it will trigger a download of the PDF file without redirecting the user or opening a new tab. Keep in mind that some browsers may still display a notification at the bottom of the screen indicating that a file is being downloaded.
Note: This method relies on the browser's built-in PDF viewer to handle the download. If a user has disabled their browser's built-in viewer or is using a browser without one, the file might open in a new tab instead of downloading. But for the majority of users, this method should work seamlessly.
