Frequently Asked Questions
Everything you need to know about ox0.in, the free unlimited AI image generator and editor. No signup, no watermark, no daily limits.
Do I need to sign up or create an account?
No. ox0.in does not require an account, email address, or payment information. You can start generating images immediately.
What AI models does ox0.in use?
We use FLUX.1 [dev] for high-quality generation and FLUX.1 [schnell] for faster results. Both are open diffusion models developed by Black Forest Labs. See the Models page for full technical details and comparisons.
What image sizes can I generate?
You can generate images in three aspect ratios: 1024×1024 (square), 1024×1536 (portrait), and 1536×1024 (landscape). All outputs are up to 2 megapixels.
How do I write a good prompt?
Include the subject, style, setting, and details such as lighting or camera angle. Our Prompting Guide has examples and tips to help you get better results.
How do I remove a background perfectly?
Use a high-resolution image with a clear subject and contrasting background. See the Background Removal Guide for detailed tips, best practices, and use cases.
Can I remove the background from any image?
Yes. Upload any PNG, JPG, WEBP, BMP, GIF, or TIFF image and the tool will produce a transparent PNG. The Background Removal Guide explains which images work best.
Where are my generated images stored?
Successful generated images appear in the Gallery. We keep the 100 most recent successful generations; older images are automatically deleted to manage storage.
Can I use generated images commercially?
Generated images can generally be used for personal and many commercial purposes, depending on the model's license. FLUX.1 [schnell] is Apache 2.0 licensed and is the safer choice for unrestricted commercial use. FLUX.1 [dev] has its own non-commercial/commercial licensing terms from Black Forest Labs. We are not lawyers; please review the upstream license if you plan to use images commercially.
Why do I see ads on the site?
Advertisements help us keep image generation free. We use Google AdSense and follow Google's publisher policies. You can learn more about ad personalization in our Privacy Policy.
Is there a usage limit?
There are no hard daily limits for casual users. We monitor usage to prevent abuse and keep the service fast for everyone. If you need heavy volume, please contact us.
What if my image generation fails?
Generation can fail due to upstream queue overload or network issues. Try again with a shorter or simpler prompt, or switch to FLUX.1 [schnell] for faster, more reliable generation.
