A maker for the banner image (channel art) that appears across the top of your YouTube channel. The output is fixed to the recommended upload size of 2560×1440px. A YouTube banner shows a different amount on each device — desktop shows a wide strip (full width × 423), TV shows the whole image, and phones show only a central portion. The trick is to keep your text and logo inside the central 1546×423px safe area that is guaranteed to show on every device; place them outside it and your channel name gets cropped on mobile (the usual cause of a banner that 'doesn't fit'). This tool overlays that safe area as a dashed guide, plus the desktop-visible strip, so you can position everything where it won't be cut. Type your channel name (heading) and an optional caption line, then set the text position (top, center, bottom), alignment (left, center, right) and font (sans or serif); text is always auto-placed and shrunk to stay inside the safe area. The background can be a plain color or an image that fits (cover) to fill the banner, and when art is present you can lay a soft shaded band behind the text for readability. Add an accent-colored underline beneath the heading if you like. When you're done, press Save PNG to export the 2560×1440 image (the guide lines are not included in the export) and upload it from YouTube Studio → Customization → Branding → Banner image. Your image and text are never sent to a server — everything runs in your browser (only settings like position and colors are stored on your device for next time and can be cleared with Reset).
