In 2026, the recommended YouTube thumbnail size is 3840 x 2160 pixels. You can still use lower resolutions with a 16:9 aspectratio, like 1280 x 720 pixels, but your image probably won’t look as good after it’s been automatically compressed and resized for display.
TipUse Quillbot’s free YouTube Thumbnail Templates tool to design your custom YouTube thumbnails. When exporting the finished design, select “3840 x 2160” in the file type options menu.
Choose JPG if the main element of your thumbnail is a photo or a video still, or if the quality of gradients or shadows is important. Choose PNG for sharp logos, illustrations, text, or icons.
The YouTube video thumbnails you can upload to replace the automatically generated versions are called “custom thumbnails.” Make them as large as possible in a 16:9format, keeping the file size under 50 MB (2 MB when uploading on a mobile). You can only use custom thumbnails for standard videos, not for YouTube Shorts.
The recommended size for a YouTube thumbnail for a podcast in 2026 is 1280 x 1280 pixels. Podcast thumbnails should be in a 1:1 aspect ratio.

The old adage says, “Don’t judge a book by its cover.” While this is a useful mindset when it comes to people, it rarely applies to actual books. For good or for bad, a book’s cover very often affects if—and how widely—it gets read.
For authors, that creates a clear challenge: How do you design a cover that stands out without spending hundreds on a professional designer or learning complex design software? How do you explain your ideas to your publisher to make sure your work really shines?
A bookcovergenerator offers a practical solution. Quickly explore and mock up ideas so that when it’s time for your book’s cover to be designed, you have concrete, visual ideas to help you make decisions. Quillbot’s Book Cover Generator is one of these tools, and it’s free and easy to use.
If you’ve ever had to source materials or digital assets, you know this scenario all too well.

Whether you need fabric, wallpaper, floor tiles, or digital backgrounds, you shouldn’t have to compromise with off-the-shelf options. With an AI pattern generator, you can quickly explore and visualize design ideas. Quillbot’s Pattern Generator is completely free to try.
