AI Logo Prompts | Tips, Examples & Templates

Using an AI image creation tool—like QuillBot’s free online AI logo generator—is a quick and easy way of realizing your logo ideas as professional-looking visuals. This guide walks you through how to plan and refine effective AI logo prompts and includes example phrases and templates you can adapt for your own designs.

How to write logo design prompts

AI tools are getting better and better at understanding instructions written in natural, everyday language, so writing an effective logo prompt is less about using special “prompt engineering” tricks and more about clearly communicating your logo concept and fine-tuning it through trial and error.

Here are some tips to help you draft and fine-tune your logo prompts.

1. Project your brand

Before generating your first logo image, develop the prompt with the help of an AI chatbot or a tool like QuillBot’s free prompt generator. Start by telling the AI about the brand, group, or project you’re creating the logo for. Describe its values (e.g., innovation, sustainability, creativity) and its personality (e.g., playful, minimalist, trustworthy, bold). Then ask the AI to turn that information into a draft prompt you can test out.

2. Aesthetic

If you already have a design direction in mind, include words and phrases in your prompt that describe the overall look and feel (e.g., modern and clean, calm and organic, elegant and minimalist) or the artistic style you want (e.g., watercolor, abstract, line art).

3. Design details

You can also add specifics about color (e.g., vibrant palette, muted tones, monochrome) and composition (e.g., circular emblem, wordmark, abstract icon).

Generating a professional-looking logo with AI is an iterative process. If a prompt gives you results that are close to what you want, try producing several variations before rewriting it—most tools create slightly different images each time.

When fine-tuning a prompt, adjust one detail at a time so you can see what’s changing the output. If the model keeps adding unwanted elements, try using negative instructions such as “no shadows,” “no text,” or “no background.”

Before using your AI-generated logo, make sure it doesn’t infringe on any existing trademarks. An attorney can help you with trademark clearance for logos.

Frequently asked questions about AI logo prompts

Can QuillBot’s free AI logo generator be used without a watermark?

Yes, there is no watermark on the images produced by QuillBot’s free AI logo generator.

What are some good logo fonts?

Good logo fonts are distinctive, scalable, and legible across different sizes and contexts. Choosing a font is one of the most important steps when you design a logo.

Popular fonts include sans-serifs (e.g., Futura, Helvetica) for clean looks, serifs (e.g., Bodoni, Didot) for elegance, and slab serifs (e.g., Rockwell, Museo Slab) for strength. Scripts (e.g., Pacifico, Satisfy) add creativity, while display fonts (e.g., Bebas Neue, Rift) make bold statements.

Try QuillBot’s AI logo generator to experiment with what fonts look good for your brand.

What size should a logo be?

Logos don’t have one fixed size; they should scale for different uses. When learning how to design a logo, you’ll find that this is one of the most important qualities of a logo.

A common size for a website logo is about 250–400 pixels wide by 70–100 pixels high. You can really design your logo in any size, but make sure you do so in vector format (e.g., SVG) so it looks sharp if you shrink or enlarge it.

QuillBot’s AI logo generator can help you experiment with different logo sizes.

What is a good logo file format?

PNG is a good logo file format because it supports transparent backgrounds, allowing you to place your logo cleanly on any design without a visible box around it.

PNG also uses lossless compression, which preserves sharp edges and clear text.

QuillBot’s free AI logo generator exports PNG files by default. If your image isn’t already transparent, you can use QuillBot’s free background remover to clear the background. And if you need to convert a JPEG into a PNG, use QuillBot’s free online JPEG converter
