About the YouTube Thumbnail Maker
A good thumbnail is often the reason someone clicks your video. This maker builds YouTube thumbnails at the recommended 1280 × 720 pixels: add a background photo (or use a colour gradient), write a short headline in big outlined letters, add an optional second line and a bright corner badge like NEW or PART 2. The text shrinks automatically to fit, you can move it left, centre or right and top, middle or bottom, and a dark fade keeps it readable on busy photos. Download a JPG under YouTube's 2 MB limit or a PNG. Nothing is uploaded and there's no watermark.

What makes a thumbnail work
Thumbnails are seen small, next to many others. High contrast, a single clear subject, a face showing emotion and a few large words stand out. Keep the most important part away from the bottom-right corner, where YouTube places the video length.
- One idea per thumbnail
- 3–5 words at most
- Strong contrast between text and background
- Consistent colours across your channel
Using a frame from your video
Pause your video at an expressive moment, take a screenshot, and add it as the background. The maker crops it to 16:9 from the centre, so keep the subject roughly in the middle. Our Screenshot Tool can capture a frame on a computer.
Text that stays readable
The thick outline and darkening keep text legible on any photo. White or yellow text with a black outline is the classic choice. The headline shrinks until it fits in three lines, so shorter text stays bigger; split long titles between the headline and the second line.
Checking how it looks small
Before uploading, view the downloaded image at a small size, about the width of your thumb on a phone screen. If you can't read the words, shorten them or make them larger.
File size and format
JPG keeps the file small, well under YouTube's 2 MB limit at 1280 × 720. PNG gives perfectly crisp text but larger files; it is useful if you want to edit the image further in another app.
Phone and computer
The preview sits above the controls on a phone and beside them on a computer. Fonts come from your device, so Impact and Arial Black may look slightly different on some phones. To trim a picture first use Crop Image, and the Image Resizer sets the exact size.

Frequently asked questions
What size is a YouTube thumbnail?
1280 × 720 pixels (16:9), at least 640 pixels wide, under 2 MB, as JPG, PNG or GIF. This maker always outputs 1280 × 720.
How do I upload a custom thumbnail?
In YouTube Studio, open the video's details, choose Upload thumbnail and pick the downloaded file. Your account may need phone verification to use custom thumbnails.
How many words should a thumbnail have?
As few as possible: three to five big words read well even on a small phone screen. Let the title carry the details.
Can I use any photo?
Use photos you took or have the rights to, such as frames from your own video. Avoid copyrighted images and misleading pictures, which break YouTube's policies.
Why is there a dark fade?
Text is easier to read over a darker area. Set the darkening to 0 if your photo already has a calm area behind the text.
Does it add a watermark?
No. The image is yours, with no logo or watermark.
Is my photo uploaded?
No. The thumbnail is drawn in your browser and saved straight to your device.
