A banner has two constraints that generation handles badly: it must be an exact pixel size, and it usually contains text that has to be readable and correct. Free template tools solve both. Generation supplies the artwork that goes inside them.
TL;DR
- Free template tools are the answer. Exact sizes, real type, free export
- Generate the background, set the type in an editor. Generated text garbles
- On 8frame: Seedream 5 at 6 credits per direction, Imagen 4 Fast at 4 for volume
- Get the exact pixel dimensions from the platform or ad network first, and never guess
- Design at the smallest size you will ship. Banners are small and legibility decides everything
Why templates win here
Exact dimensions. Ad networks and platforms specify pixel sizes precisely, and a banner at the wrong size is rejected. Template tools have those sizes built in; a generated image comes out at whatever the model produces.
Real type. A banner's text is usually the whole message, and generated text inside an image is unreliable: wrong words, invented characters, spelling that changes between attempts. For an ad that is disqualifying.
A size set. One campaign needs the same banner in six or eight dimensions. Template tools resize; generation produces a new composition each time.
File size limits. Ad networks cap them, and template tools export accordingly.
Where generation fits
Background artwork. Something specific rather than a stock gradient. Seedream 5 at 6 credits per direction, so twenty for 120.
Texture and pattern. Subtle surface behind the message.
Illustrative elements. A motif, a decorative device, a thematic image.
Concept exploration. Twenty visual directions to find the approach before building the size set.
Product imagery, composited. Photograph the real product, cut it out at 12 credits, place it on a generated background. Never generate the product itself.
What it costs
Canon 8frame prices, a credit is $0.01 at pack rate:
| Task | Route | Credits |
|---|---|---|
| Background direction | Seedream 5 | 6 |
| Cheapest volume exploration | Imagen 4 Fast | 4 |
| Element with exact text | Nano Banana Pro | 21 |
| Cut out a real product | background removal | 12 |
| Adjust artwork | Flux Edit | 7 |
| Upscale for a large placement | Clarity | 13 |
A campaign's artwork: twenty directions (120), one product cutout (12), two edits (14), one upscale (13) is about 159 credits, roughly $1.59. The size set is free in a template tool.
The rules that make a banner work
Design at the smallest size in your set. If it works at 300x50, it works everywhere. Designing at the largest and scaling down is how the text becomes illegible.
One message. A banner gets less than a second. Two messages is none.
Text over a quiet area. Prompt for it: "uncluttered left third." Type over busy artwork is unreadable, and a plate behind the text is the reliable fix.
High contrast. Banners appear against unpredictable page backgrounds.
Readable at a glance, not at leisure. Three to six words at level one.
Include the call to action as a distinct element, not as part of a sentence.
The check before you ship
- Exact dimensions against the platform spec, for every size in the set
- File size under the network's cap
- Text legible at 100 percent, on both light and dark page backgrounds
- The link works and goes where it should
- Every claim in the copy verified by someone who knows
That last one is the expensive error, and it is not a design problem.
FAQ
What is the best free banner maker? A free template tool. It handles exact sizes, real type and export limits.
Should I generate the whole banner? No. Generate the background, set the type in an editor.
How much does banner artwork cost? About $1.59 in credits for twenty directions plus edits.
What size should I design at? The smallest in your set. If it reads there, it reads everywhere.
Generate the background, set the type, design at the smallest size. The 8frame canvas is free and unlimited, and generation is paid from $19/month.
