Yes, you can! You can use the free version of Remini to enhance a limited number of photos per day. You’ll just need to watch a couple of ads while Remini works its magic.
And if you're curious to try out the Pro version and experience the full wonders of Remini without ads or upload limits, you can easily start a one-time free trial.
Once the trial is over, it’s your choice whether to continue with a subscription to Remini Pro or to cancel your plan and return to the free version. To avoid unwanted charges, remember to cancel the automatic subscription no less than 24 hours prior to the end of your free trial.
