Supported formats

JPEG, PNG, WebP, and AVIF (availability depends on your browser). Transparency is preserved in PNG and WebP; JPEG/AVIF are opaque.

Resize modes explained

  • Percent: 50% halves both width and height.
  • Long/Short Edge: set one edge; the other scales to keep aspect.
  • Max WxH: scales to fit inside the box (no crop).
  • Cover: fills the box and may crop overflow (good for social banners).
  • Contain: fits inside and pads the rest (pick a background color).

Tips

  • For small web files, try WebP or AVIF with quality around 70–85.
  • Use Long Edge to quickly make 1920 px or 1280 px variants.
  • Use Cover for perfect social-ready canvases without manual cropping.
