Is the image generator really free?

Yes. Every account gets 20 credits a month with no card and no trial that runs out. Paid plans add more credits and let you run several generations at once.

Is there a watermark?

RenderHour adds no watermark to results, on the free plan or any other.

How long are free results kept?

Results on the free plan are kept for 30 days, so download what you want to keep. On a paid plan they stay until you delete them.

What happens when the free credits run out?

Next month’s credits arrive on the day your account was made; unused ones do not carry over. If you need more before then, plans start at $10 a month for 250 credits.

How it works

Sign up with Google. The free credits are on your balance straight away, with no card.
Open the Image page, pick one of the models below and write your prompt or add a photo.
The price is on the Generate button and comes off your free credits.
A failed run costs nothing. The credits renew every month, counted from the day you signed up.

Tips

Draft with Z-Image, then make the final picture with a stronger model.
Pick the lowest resolution while you try ideas; the price on the button changes as you do.
Free credits do not carry over, so use them before the next month’s arrive.
