Resizing and aspect ratio
Aspect ratio is the relationship between width and height. Keep it locked to avoid stretching; turn it off when you deliberately need exact dimensions. Presets may use a different ratio and therefore unlock it.
Preset dimensions
Use 32×32 for a small favicon, 180×180 for an Apple touch icon, 256×256 for avatars, 1080×1080 for square social posts and 1200×630 for Open Graph previews.
FAQ
Can enlarging improve quality?
No. Enlarging interpolates existing pixels but cannot recreate missing detail.
Which output format should I choose?
Use PNG for transparency or sharp graphics, JPG for photographs, and WebP for efficient modern web images.
