Image Crop to Ratio Tutorial

What This Does

Smart-crops your image to a target aspect ratio without distortion. Picks the largest possible region that fits the ratio, anchored at center by default. Useful for social media uploads, thumbnails, banner images.

Common Ratios

  • 1:1 — Instagram square posts
  • 4:5 — Instagram portrait posts (taller, more screen real estate)
  • 16:9 — YouTube thumbnails, hero banners, presentations
  • 9:16 — Instagram/TikTok Stories, Reels, vertical video thumbnails
  • 4:3 — older TVs, projectors, photo prints
  • 3:2 — DSLR sensor native ratio, classic photo prints
  • 21:9 — ultrawide cinematic banners

Anchor Position

When the source ratio differs from the target, the tool has to discard some pixels. The anchor controls which region is kept.

  • Center — default; balanced for most photos
  • Top — keep heads in portraits when cropping to landscape
  • Bottom — keep feet in full-body shots
  • Left/Right — keep one side
  • Corners — for very specific compositions

Privacy

The image goes to our FC function for cropping (Pillow needs server-side compute) and is discarded after the response. Nothing is stored.
