Upload Your Image

Start by uploading any image you want to extend or expand:

Supports JPG, PNG, WebP, HEIF formats (up to 10MB)
Resolution must be between 512×512 and 4096×4096 pixels
Higher resolution images produce better extension quality

⚖️

Proportional Scale

Uniformly expand images while maintaining their original aspect ratio.

Parameters:

• X-Scale: Horizontal expansion (0.1–3.0×)
• Y-Scale: Vertical expansion (0.1–3.0×)
• Rule: At least one of X/Y must be > 1.0
• Default: 1.5× for both directions

📱

Target Aspect Ratio

Transform images to specific aspect ratios for social media and standardized formats.

Available Ratios:

• 16:9: Widescreen (YouTube, presentations)
• 9:16: Vertical (Instagram Stories, TikTok)
• 4:3: Standard (traditional photos)
• 3:4: Portrait (print photos)
• 1:1: Square (Instagram posts)

If the current image already matches a selected ratio, generation is disabled with a hint.

📐

Directional Offsets

Add specific pixel amounts to individual edges for precise control.

Parameters:

• Left/Right Offset: 0 to max pixels (sum must be < 3× image width)
• Top/Bottom Offset: 0 to max pixels (sum must be < 3× image height)
• Use Case: Asymmetric extensions and precise edge control
• Rule: At least one of the four offsets must be > 0
• Example: 1000×1000 image allows up to 2999px total horizontal/vertical expansion

🔄

Rotate & Extend

Combine rotation with scaling for creative compositions.

Parameters:

• Angle: 1–359° (not allowed: 90°, 180°, 270°)
• X/Y Scale: Optional after rotation; 1.0 means no scaling
• Default: 91° + 1.0× scaling

Parameter Priority & Rules

Priority: output_ratio > x_scale/y_scale > offsets. angle can coexist (rotate first, then extend).
Scale: At least one of X/Y must be > 1.0; range 0.1–3.0.
Offsets: Left+Right < 3× image width; Top+Bottom < 3× image height.
Image Requirements: JPG/JPEG/PNG/HEIF/WEBP; ≤10MB; resolution 512–4096; side length within 512–4096.
