I already have a YouTube banner, but its raster edges become fuzzy and distorted once it scales across devices. I need the artwork rebuilt so it remains perfectly sharp on both mobile and desktop while preserving its current layout. The finished piece should feel professional and lean toward a dark, sleek palette—nothing loud or playful—matching the overall tone of the channel. Make sure all safe-area guidelines are respected so key visuals stay centered and readable on every screen size. Please supply: • A high-resolution, web-optimized banner that meets the official 2560 × 1440 spec (with the 1546 × 423 “safe zone” correctly aligned) • The editable source file (PSD or AI) with neatly organized layers for any future tweaks The work is accepted once the design looks crisp at full 4 K width, standard desktop, tablet, and mobile preview without pixelation or stretch artifacts.
