Frequently Asked Questions
What size should YouTube thumbnails be?
YouTube recommends 1280×720 pixels (16:9 ratio) with a minimum width of 640 pixels. File size must be under 2MB. JPG, GIF, or PNG formats accepted.
Why is my thumbnail blurry on YouTube?
Either your source image was too small (under 1280×720) and got stretched, or you used too much compression. Start with at least 1280×720 and use 80%+ quality.
What makes a good YouTube thumbnail?
High contrast, readable text (if any), faces with expressions, bright colors, and simple composition. Thumbnails are small on mobile, so avoid clutter.
Should I use PNG or JPG for thumbnails?
JPG is usually better — smaller file size means faster upload. Use PNG only if you have text that needs to stay crisp or need transparency (rare for thumbnails).
Can I use a different aspect ratio?
YouTube will add black bars (letterboxing) if your image isn't 16:9. Always use 1280×720 or another 16:9 size to avoid this.
