YouTube Shorts Maker — Free 9:16 Shorts Designer

Shorts move fast. You have less than half a second to convince someone not to swipe away. A strong thumbnail (or cover frame) does the heavy lifting. This tool is a dedicated YouTube Shorts thumbnail maker, pre-sized to the exact 9:16 vertical format (1080x1920) used by Shorts, TikTok, and Reels. Drop your image, add high-contrast text, and export a cover that hooks attention immediately.

How to make a Shorts thumbnail

  1. The canvas is pre-sized to 9:16. Upload the most expressive, dramatic, or interesting still frame from your video.
  2. Crop and scale it so the main subject fills the screen. Small details get lost on phones.
  3. Add a text layer. The title should be maximum 3-4 words. Choose a heavy font (like Impact or bold sans-serif) and color it bright yellow, green, or white.
  4. Add a dark shadow or a solid outline to the text so it stands out against the background no matter what colors are behind it.
  5. Export and upload. (Note: YouTube's mobile app allows you to select a frame from your video as a thumbnail. Many creators edit this custom thumbnail frame into the very beginning or end of their video file so they can select it during upload.)

Frequently asked questions

What size is a YouTube Shorts thumbnail?

1080x1920 pixels, 9:16 vertical — the same frame as the video. This editor's canvas and export are preset to exactly that.

Is this free, and is there a watermark?

Free, no watermark, no signup. The editor runs in your browser and your images are never uploaded to any server.

Can I reuse my Instagram Reels cover as a Shorts thumbnail?

Usually yes — both are 9:16. Give the text a size check and keep important elements in the middle of the frame, since the two platforms crop and overlay differently.

How do I set a custom thumbnail on a Short?

Options vary by device and change over time — YouTube has historically allowed selecting a frame in the app, with custom uploads available in some cases. Design the image here, then follow whatever the current upload flow in YouTube Studio offers.

Why does my thumbnail text look unreadable on the channel page?

It's rendering at a small tile size. Use fewer, bigger words — two to four words at very large size, high contrast, and check the design zoomed out before exporting.
