Do I need to mark the edges before describing the extension?
No! Just describe the direction: 'extend to the right' or 'expand upward.' The AI understands directional instructions without marking. Only use markers if the AI extends the wrong edge, which rarely happens when you're clear about direction.
How much can I extend an image in one go?
You can typically double an image's size in one direction, but results are better with moderate extensions (20-50%). For major expansions, extend in stages: add 30% to the right, review, then add more. This gives the AI better context at each step and produces more natural results.
Can I extend in multiple directions at once?
Yes, absolutely. Type 'extend left and right equally' or 'expand in all four directions to add a border.' The AI handles multi-directional extensions well, especially for symmetric expansions. For complex scenes, you might get better results extending one direction at a time.
Will the extended area match my image quality?
The AI generates content at your original image's resolution. High-resolution source images produce high-resolution extensions. If your original is 4000px wide and you extend right, the new pixels match that quality. Low-resolution sources will produce matching low-resolution extensions.
What if I need a specific final aspect ratio like 16:9?
Mention the target ratio directly: 'extend to create a 16:9 landscape aspect ratio' or 'expand to fit 9:16 vertical format.' The AI understands common aspect ratios and calculates how much extension each direction needs. You can also say 'extend right by about 30%' for proportional control.
