Convert a file in the browser extension

Goal: Your file in the format you need, downloaded without leaving the tab you're on.

Before you start

Install the extension from the extensions page . It runs in a desktop browser.
Sign in to your indox account in the extension. Unlike the website, the extension needs an account.

Select the INDOX icon in your browser's toolbar. The side panel opens beside your page.

Select Choose a file and pick your file.

Select a format, such as PDF. For other formats, select More formats.

Check the credits the job will use, shown under the button, then select Convert.

When the file shows DONE, select Download result. The file also stays in History, so you can download it again later.
