# Thumbnail Maker

Describe the video and the reaction you want the cover to trigger, and Made generates a bold 16:9 thumbnail as a PNG — strong focal point, saturated colors, and optional title text.

## How to use Thumbnail Maker

1. **Describe the hook**
   Say what the viewer should feel in half a second — the subject, the expression or action, and the payoff the video promises.
2. **Add short title text**
   Keep rendered text to a few punchy words and spell them exactly. Proofread the result — thumbnail text is read at a glance and typos are conspicuous.
3. **Ask for thumbnail composition**
   Request high contrast, a single focal point, and bold outlined text; mention that it must stay readable at small sizes.
4. **Generate, compare, download**
   Each run is a new render. Generate a few options, shrink them down to feed size to judge them, and download the winner as a PNG.

## What people use it for

- **Video covers without a shoot** Generate a thumbnail when you have no usable still from the footage — describe the scene the video promises and render it directly.
- **Testing concepts** Render several thumbnail directions for the same video and compare which composition and text treatment reads best at small sizes.
- **Podcast and series covers** Create consistent cover images for episodes by reusing one style description and changing the subject and title text.
- **Course and tutorial cards** Make clean 16:9 cards for lesson libraries and course platforms where every module needs a distinct but matching cover.

## Make a video thumbnail from a description

### What it does

**Input**

A text prompt describing the video topic, the visual hook, and any title text; no image required

**Output**

16:9 PNG thumbnail at 1K resolution

**How it works**

Made sends your description to the Nano Banana 2 model on fal.ai and returns a PNG at 1K resolution; GPT Image 2, Grok Imagine Image 2, and Nano Banana 2 Lite are available as alternates, and Google’s Imagen 4 on Replicate is the fallback when fal.ai is not configured.

**Access**

Set up the request on this page. You sign in to run it, and each run is priced in credits before you start.

### Formats and limits

**Input**

Text prompt (required) describing the topic, visual hook, and title text

**Output format**

PNG at 1K resolution on the default model

**Aspect ratios**

16:9 for standard video covers; 9:16 for vertical formats and 1:1 for podcast tiles

**Rendered text**

Short titles render best; proofread and regenerate to fix spelling

**Exact platform sizes**

Generate at 16:9, then use Image Resizer to hit an exact pixel spec such as 1280 × 720

## Questions about Thumbnail Maker

**How does the thumbnail maker work?**

You describe the video’s hook — the subject, the moment, and any title text — and Made sends the description to the Nano Banana 2 image model, which renders a 16:9 cover image and returns it as a PNG at 1K resolution. Generate a few takes and pick the one that reads best small.

**Can I make a thumbnail with my own face or photo?**

Not on this page — this workflow generates entirely from text, so the people in the render are generated, not you. To build a thumbnail from your own photo — cut yourself out, boost the colors, add text and a background — upload the photo to the AI Photo Editor instead.

**Will the text on the thumbnail be spelled correctly?**

Current models render short text well, but spelling is not guaranteed on every run. Keep titles to a few words, put the exact wording in your prompt, and proofread before publishing — regenerate or rephrase if a letter drifts.

**What size is the thumbnail, and will video platforms accept it?**

The output is a 16:9 PNG at 1K resolution, which matches the shape video platforms expect. If your platform asks for an exact pixel size such as 1280 × 720, run the result through Image Resizer; PNG uploads are broadly accepted.

**What makes a thumbnail prompt work?**

Design for the glance: one clear subject with a strong expression or action, a high-contrast background that separates from the platform’s white or dark UI, and no more than about four words of text. Say “readable at small sizes” in the prompt — it pushes the model toward bolder, simpler compositions.

**Can I keep a consistent style across my channel?**

Yes, by treating the style as a reusable template: fix the palette, text treatment, and layout in one description and change only the subject and title per video. Each generation is a new render, so expect sibling-level consistency rather than identical frames.

**Can it make vertical covers for short-form video?**

Yes. Switch the aspect ratio to 9:16 for vertical formats, and keep the focal point centered since short-form UIs overlay buttons and captions along the edges. The same prompt principles apply — one subject, high contrast, minimal text.
