AI thumbnail maker for YouTube, Shorts and covers
A thumbnail decides whether a video gets clicked. Pick a finished video, and Quorvid builds a thumbnail from its best frame or from an AI-generated background, with a headline on top.
Two ways to build a thumbnail
- From your video's frame (free): Quorvid picks a sharp, colourful frame from your video and adds the headline. No credits are used.
- From an AI background: a new image is generated to match your video, then the headline is added. This costs 4 credits.
Sizes that fit the platform
The thumbnail follows the shape of your video: a 16:9 video gives a 1280 × 720 thumbnail (YouTube's recommended size), a 9:16 video gives 720 × 1280 and a 1:1 video gives 1080 × 1080.

- AI image generator: create images from a text description in many aspect ratios.
- Upscale: enlarge a picture up to four times for 2 credits.
- Remove background: cut out a subject as a transparent PNG for 4 credits.
A simple workflow
- Finish your video in Quorvid so it appears in your library.
- Open the thumbnail maker for that video and try the free frame option first.
- If the frame isn't striking enough, switch to an AI background.
- Type your own headline, or leave it blank and one is written from the video.
- Download the image and upload it with your video.
Tips for better thumbnails
- Keep the headline short, ideally a few words.
- Use high contrast so it still reads at small size.
- Make sure the image honestly reflects the video.
