Upgrade to Pro

Visit the license retrieval page and enter your purchase email address there. The key number will be sent to the email right away.

Make sure you’re typing the email address in lowercase including the first letter. Our system may not recognize your address if it starts with a capital letter - as a result, the license information won’t be sent.

In case you still can’t obtain the key number, contact our support team.

Copy the number of your license key and paste it into the specialized form above, here on the upgrade page.

Once you’ve placed the upgrade payment, a new Pro license is going to be generated and sent to your purchase email address. Activate it in the application to unlock the Pro features.

Copy the key number of one of the licenses from your bundle - it can be a key for any 4K Download application. Paste the license key into the upgrade form located above on this page.

Once you’ve placed the upgrade payment, a set of three Pro license keys will be sent to the purchase email. Activate the licenses in 4K Stogram, 4K Video Downloader, and 4K YouTube to MP3 applications to unlock the Pro features.

Unlike standalone Personal and Pro licenses, keys from the license bundles cannot be upgraded separately. If you upgrade one license of the bundle, the other two automatically upgrade as well.

It’s impossible to downgrade both the bundles and single licenses.

If you’ve lost access to your purchase email or can’t upgrade due to other reasons, please contact our support team to sort the issue out.
