You choose the settings - nothing is silently downscaled or recompressed.
The recommended size is 1280x720 pixels, an aspect ratio of 16:9, with a minimum width of 640 pixels. Larger files look sharper on big screens.
YouTube accepts thumbnails up to 2 MB in JPG, PNG or GIF format. If your image is bigger, lower the quality or run it through the image compressor.
A channel banner should be 2560x1440 pixels, with the important content in the central safe area. That size is available in the preset list.
Choose Crop to fill to cover the frame and trim the overflow, or Stretch to force the exact size. Cropping avoids distortion and is usually the better choice for thumbnails.
