Frequently Asked Questions
Is this image generator really free?
Yes — no signup, no watermark, no trial limits. Fair-use queueing at peak hours keeps it free for everyone.
What sizes and ratios are supported?
Choose from 1K to 4K resolution with aspect ratios 1:1, 16:9, 9:16, 4:3, 3:4, 2:3, 3:2, and 21:9.
Who owns the images I create?
You do — personal and commercial use. See the Terms page for details.
Why does generation take a few seconds?
Each image renders on shared AI capacity. The API responds directly — usually 2-10 seconds.
What makes a good image prompt?
Describe subject + style + lighting + mood in one sentence — subject first, then details. Specific prompts consistently beat vague ones.
Is there a generation limit?
Yes — up to 15 images per day per network. There is no waiting time between images any more, so you can make them back to back. Need more for a project? Email [email protected] and we raise the limit for your IP.
Which size is best for YouTube thumbnails?
16:9 at 2K or higher — sharp enough for thumbnails with room to crop. Use 9:16 for Shorts covers and Reels.
