Frequently Asked Questions

What dimensions should I use for social media?
Instagram: 1080×1080 (square), 1080×1350 (portrait). TikTok/Reels: 1080×1920. YouTube: 1920×1080. Twitter/X: 1280×720.
Will resizing reduce quality?
Upscaling (making larger) can look blurry. Downscaling (making smaller) preserves quality well. Use the 'Best' encoding preset for maximum quality.
