Free AI logo maker: from prompt to vector in minutes

A logo is the smallest asset you will ever brief — and the one you will live with the longest. AI logo makers collapsed the cost of exploring directions from a week of back-and-forth to an afternoon. The trick is knowing what to give the model, and what to fix by hand. This guide walks through the whole loop using free.logo.

Write a brand brief, not a prompt

Models respond to concrete nouns and constraints, not adjectives. A useful logo prompt has four parts: what the business does, who it serves, the visual metaphor, and the style rules.

• Subject: "a courier company for small bakeries" beats "a logistics brand".
• Metaphor: "a paper plane folded from a croissant" gives the model something to draw.
• Style: "flat, two colours, thick strokes, geometric" — pick three constraints, not ten.
• Avoid: "no gradients, no photorealism, no text" (wordmarks are a separate lockup).

Choose the right lockup

Icon marks scale to favicons; wordmarks read in signatures; horizontal lockups fit headers; stacked lockups fit packaging. Generate the same concept in more than one lockup so you are not re-drawing later — free.logo composes each variation with production margins.

Insist on vector output

A PNG looks fine on screen and falls apart on a banner. Vector-capable models output real SVG, which stays crisp at every size and can be recoloured by any designer. If the model you try only returns raster, treat it as a concept pass — then refine on a vector model from the catalog.

Iterate one change at a time

The fastest way to ruin a good mark is to re-roll everything. Select the variation you like, change exactly one thing — rounder corners, simpler geometry, a different accent colour — and refine. Repeating that loop beats twenty random generations.

Start free, generate a few directions, and refine the winner in free.logo. No watermark, and every generation shows its credit cost before you run it.
