Dimensions & Generation Guidelines
Understand the performance boundaries and auto-optimization logic of AI outpainting
Total Pixel Limit
To ensure optimal quality and speed, the total pixels are limited to 2.56 million (1600x1600). If the target size exceeds this, the original image will be automatically scaled down to fit.
Auto Scale Large Images
If the uploaded image resolution is too high (exceeding 2.56 million pixels), the system will automatically scale it down proportionally to fit within this limit.
Non-Multiple of 8 Adjustment
If the original image's width or height is not a multiple of 8, there might be slight pixel stretching (up to 7 pixels) during generation, which is usually imperceptible.
Follow these steps to extend your image
Select Dimensions：Click preset ratios like 16:9 (video cover) or 4:3 (wide), or drag directly on the canvas to control size.
Enter Prompt (Optional)：Tell the AI what you want, like "extend the sky" or "fill the left forest." If left blank, AI will imagine it automatically.
Upload Image：Click to upload or drag images in directly. Supports both single and batch processing.
Generate Now：Click to start processing. The AI will seamlessly extend your image background in seconds. Download if satisfied.
Batch Outpainting
Import dozens of assets at once and use horizontal/vertical sliders to define the extension direction. Whether unifying e-commerce top margins or extending posters to the right, AI handles batches instantly, boosting efficiency 10x.
Free Size Extension
No longer limited to fixed ratios. Drag edges freely on the visual canvas to precisely control padding on all sides, meeting 16:9, 9:16, or any custom size needs.
Social Media Size Adaptation
AI intelligently adapts to platform sizes like TikTok, Instagram, and YouTube. Automatically fills backgrounds while preserving quality, eliminating repetitive cropping for efficient multi-platform content creation.
E-commerce & Ad Whitespace
Solves the pain point of oversized product shots with no room for text. Instead of forced stretching, AI intelligently extends the image sideways, instantly creating ample "negative space" for banners or posters.

Member Benefits
Members enjoy an increased single-upload limit of 20MB, batch processing up to 15 images at once, and priority fast lanes.
Size Limits
To ensure generation quality and speed, the final output is limited to a total of 2.56 million pixels (1600x1600).
Batch Rules
In batch mode, all images will apply the same alignment and extension ratio, perfect for unified processing.
Privacy Commitment
Your original images and results are kept for a maximum of 24 hours before automatic destruction. Please download promptly.
Eliminating Artifacts
If the result feels stitched, try increasing "Mask Blur" or enabling "Seam Fix".
Blending Logic
A larger redraw area makes transitions more natural; a smaller value allows freer generation but may result in harsh edges.
User Reviews
“When working on e-commerce detail pages, I often face size mismatch issues. The AI completion effect of this tool is very delicate, and the light transitions are incredibly natural. It saves me tons of manual retouching time in Photoshop.”
“An absolute lifesaver for ruined shots! Many tightly framed photos instantly gain a cinematic feel when slightly extended outwards with AI. The processing is fast, and the output quality is solid.”
“I often need to convert 3:4 photos to 9:16 for covers. I used to stretch them awkwardly, but now AI outpainting automatically fills in harmonious backgrounds. Highly recommend it to all social media creators!”
Frequently Asked Questions
Common questions about AI outpainting technology
What is AI Outpainting?
AI Outpainting is a cutting-edge technology driven by artificial intelligence. Instead of simple stretching or cropping, it seamlessly generates new pixels around the image edges by analyzing the original textures, colors, and context. It's perfect for resizing social media images, enhancing e-commerce photos, or fixing poor framing.
Are the outpainting results realistic?
Our AI is context-aware and understands the style and lighting of the original image. It automatically generates continuous details (like natural scenery, extended streets) to ensure the extended areas blend perfectly with the original, looking as if captured in the original shot.
What image formats are supported?
Currently, it supports mainstream formats like JPG, PNG, WEBP, and BMP. For the best results, we recommend uploading high-resolution original images.
How can I precisely control the outpainted content?
AI usually infers the background automatically. If you have a specific vision, you can enter descriptions in the 'Prompt' box (e.g., 'beach background', 'European architecture', or 'add green plants'). The AI will generate content directed by your instructions.
What are the advantages of Batch Outpainting?
Batch mode allows you to upload multiple images at once and apply uniform alignment and extension ratios. This is incredibly helpful for e-commerce hero images, social media posts, or posters that require consistent styles and dimensions, vastly improving workflow efficiency.
Can I use it on my mobile phone?
Absolutely! Our website is developed with a 'mobile-first' approach, perfectly adapting to mobile browsers. You can directly upload, preview, and download HD outpainted photos on your phone without downloading any App. Enjoy a seamless experience on both Android and iOS devices.
Will the image quality decrease when processed on mobile?
No. Whether you operate on a computer or a phone, the cloud AI processing algorithms and output resolutions are identical, ensuring HD and lossless extension results.
Are my images safe? How do you handle uploaded data?
We highly value user privacy. All image transmissions are encrypted via HTTPS, and images are only temporarily stored in the cloud during processing. Once completed, they are permanently and automatically deleted from our servers. We strictly adhere to data protection standards and will not use your images for any other purpose.
Is this tool free?
We offer free trial quotas for users to explore the features. For high-frequency professional use or ultra-high-resolution output, we offer flexible subscription plans that you can choose based on your actual needs.
