Cách tạo logo bằng AI

A logo is not an illustration. It has to work in one color, at the size of a favicon and on the side of a van, and it has to stay recognizable for years. AI image generators such as Midjourney, DALL-E, Ideogram, Adobe Firefly and Recraft are useful because they make dozens of concepts in minutes. They do not know your brand strategy, and by default they lean toward detailed, glossy images that look impressive but fail as logos. Good logo prompts push the model toward simplicity. Name the style ('flat vector logo', 'minimal geometric mark', 'single color', 'thick even line weight'), the subject, the background ('plain white background') and what you do not want ('no gradients, no shadows, no text, no mockup'). Generate in batches and compare concepts, not tiny details. Most image models produce raster pixels, while a finished logo should be a vector file (SVG, EPS or PDF) so it scales without blurring. You can auto-trace a clean, high-contrast result with Illustrator's Image Trace or Inkscape's Trace Bitmap, or redraw it by hand using the image as a reference. Some tools, such as Recraft, can output SVG directly, but you should still clean up stray nodes and uneven curves. Lettering is the most common weak point. Newer models render text much better than earlier ones, but letter spacing and shapes are often subtly off. The safer approach is to generate the symbol without text and set the name in a real typeface whose license covers logo use. The common misconception is that a generated logo is automatically yours to own. In the United States, copyright generally requires human authorship, so raw generated output may not be protected, although meaningful human redrawing can help. Trademark is different: it depends on using a distinctive mark in commerce, not on who drew it. Because models learn from existing imagery and can produce look-alikes, run a trademark clearance search before you commit.
