Resize KDP Cover PDF

I already have a fully-approved wrap-around cover saved as a single high-resolution PDF. All bleed, margin, and trim guides in that file are exactly where they need to be; colours, fonts, and layout must stay untouched. The only snag is Amazon KDP’s strict canvas size: 12.425 × 9.250 inches for a 6 × 9 paperback. Their upload portal keeps rejecting my current dimensions. Here is what I need from you: • Open my supplied PDF (it was AI-generated, so no native .ai or .indd file exists). • Place it on a new canvas set precisely to 12.425 × 9.250 in, keeping the original bleed intact and all guides aligned. • Embed fonts, keep the colour profile in CMYK, and export a press-ready PDF/X-1a or PDF/X-3 that will pass KDP’s pre-flight without flags. That’s the entire scope—no redesign, shifting, or colour tweaks. Hand back a single print-ready PDF, and I can take it from there. No creative changes production formatting only Amazon KDP is rejecting my cover because it does not match the required template for my final book. Please use the correct KDP template for mu book's final page count and produce a print-ready cover PDF
