In the fast-paced world of digital marketing, standing out visually is half the battle. But with campaigns running across multiple channels, deadlines shrinking, and creative budgets tightening, marketers need tools that deliver fresh visuals fast, without compromising brand quality.

Enter AI image generation. From concept art to finished social posts, new AI tools can now help marketing teams produce professional visuals in seconds. The trick is choosing the right one for your needs and budget.

Below, we compare the five leading AI image tools in 2025 – Midjourney, ChatGPT’s image tools (OpenAI), Gemini Nano Banana, Canva’s built-in AI tools, and Adobe Firefly – with their pros, cons, costs, and what each means for marketers.

 

1. Midjourney – for standout creative direction

If your goal is jaw-dropping visuals for brand storytelling or campaign concepts, Midjourney leads the pack. Known for its distinctive, cinematic style, it’s a favourite among creative teams developing campaign mood boards or eye-catching hero visuals.

Midjourney runs through Discord, which takes a little getting used to, and offers subscription tiers from around £8 to £45 per month, depending on render speed and commercial rights.

Why marketers love it:

• Perfect for brainstorming campaign aesthetics or new brand styles.
• Produces striking, shareable imagery that performs well on visual platforms like Instagram and LinkedIn.
• Great for testing visual directions before investing in a photoshoot or designer.

Drawbacks:

• Not ideal for product accuracy or precise brand assets.
• Requires some prompt-crafting skill to get on-brand results.
• Higher tiers cost more if you need fast rendering.

Use it when: you’re building campaign concepts, exploring new visual territories, or want to inspire your creative team.

2. ChatGPT (OpenAI Image Tools) – for integrated campaigns and consistency

OpenAI’s image capabilities, available within ChatGPT or via its API, are brilliant for marketers who want to create copy and visuals in one place.

Imagine generating a LinkedIn ad headline, body text, and a matching image in a single prompt; that’s exactly what it offers. It’s particularly helpful for content calendars, blog visuals, and multi-format campaigns. ChatGPT Plus costs about £16 per month, while API users pay per image created, depending on resolution.

Why marketers love it:

• Seamlessly combines copywriting and visual creation.
• Produces consistent outputs when using saved prompt structures.
• Scales easily across campaigns if you automate with the API.

Drawbacks:

• Per-image pricing adds up if you generate large volumes.
• Visuals can be slightly generic unless you fine-tune prompts.
• Commercial licensing terms vary; always confirm before client use.

Use it when: you’re producing multiple creative variants, or need AI-generated visuals to match AI-written copy.

3. Gemini Nano Banana – for quick, reactive content

Google’s Gemini Nano Banana (part of the Gemini AI family) is renowned for its exceptional image generation quality. Integrated into Google Search, Lens, and Photos, it allows users to create and edit images directly within these platforms.

For marketers running reactive or trend-based content, this tool is ideal. Think quick post edits, background swaps, or adapting visuals for new platforms. It’s currently free or low-cost for most users within Google’s apps.

Why marketers love it:

• Instant edits, perfect for reactive marketing moments.
• Simple enough for anyone on the team to use, no design skills needed.
• Works within tools marketers already use daily.

Drawbacks:

• Limited customisation for brand style or complex imagery.
• Still early-stage – features and usage rights are evolving.
• Better for editing than generating fully new visuals.

Use it when: you’re working on agile social campaigns, quick turnarounds, or A/B testing visuals, and want to try what many marketers now claim is the best image generator out there.

4. Canva AI (Magic Studio) – for fast, branded content

Canva remains a marketer’s staple, and with its AI-powered Magic Studio, it’s now even faster.

Tools like Magic Media (text-to-image), Magic Edit, and Magic Write streamline social content creation from start to finish. You can generate visuals, drop them into brand templates, and export in platform-ready formats – all in one place.

Pricing is straightforward: Free, Pro (£12/month), and Teams, which includes shared brand kits and collaboration features.

Why marketers love it:

• Unbeatable speed and usability.
• Built-in brand controls to keep visuals consistent.
• Integrates image generation directly into content production workflows.

Drawbacks:

• Image quality isn’t the strongest right now, but it’s improving rapidly with each update.
• Less flexibility for bespoke or conceptual visuals.
• Premium features require Pro or Teams subscriptions.

Use it when: you’re managing daily content, campaign rollouts, or performance creative that needs to stay on-brand and on schedule.

5. Adobe Firefly – for professional-grade, brand-safe visuals

Adobe’s Firefly is the professional option for teams needing control, quality, and commercial certainty.

Integrated into Photoshop, Illustrator and Adobe Express, Firefly ensures generated images are trained on licensed content – so they’re safe for commercial use. It’s available free with limited credits, or bundled into Creative Cloud plans (£20–£50+/month).

Why marketers love it:

• Perfect for agencies and in-house teams needing legally clear assets.
• Advanced tools for refining visuals or compositing real product shots.
• Deep integration with the Adobe suite for editing and post-production.

Drawbacks:

• Pricier and more technical than Canva or Gemini.
