Upgrade to Pro

You can find your license key in the email you received after the purchase. In case you can’t find it, visit the license retrieval page and enter your purchase email address. The licence will be resent to the email right away.

If you lost access to the purchase email, please contact support.

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.

1. Copy the number of any licence key from your 4K Bundle Personal.

2. Paste the license key into the upgrade form located above on this page.

3. Click the Upgrade button. You will be redirected to the payment page.

Once you’ve placed the upgrade payment, a set of Pro license keys will be sent to your purchase email.

4. Unlock the Pro features. Activate the licenses for 4K Stogram, 4K Video Downloader+, 4K Video Downloader for Android, 4K YouTube to MP3, 4K Tokkit and 4K Image Compressor in the respective applications.

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.
