Social Media Image Crop
Crop images to popular social media dimensions
Social Media Image Crop — what it does
Crop an image to a popular social media dimension using a preset, with control over whether the crop is taken from the centre, the top or the bottom. Each platform enforces its own aspect ratio, and cropping deliberately beats letting an upload form cut wherever it likes.
When this tool helps
- Preparing a post image at the exact ratio a platform displays without cropping it further.
- Producing a square version of a landscape photo without losing the subject.
- Making a story or vertical-format crop from a horizontal original.
How to use it
- Choose the image.
- Select the preset for the platform and format you need.
- Choose whether to crop from the centre, top or bottom.
- Process and download the cropped image.
Accuracy, limits, and good practice
- Crop position is the decision that matters: centre works for most photos, top keeps heads in frame, bottom keeps foreground subjects.
- Platforms crop previews differently from the full view, so keep the important content away from the extreme edges.
- Cropping never adds pixels — a small source cropped to a large format is simply a smaller image, not a lower-quality larger one.
Frequently asked questions
Which ratio should I use?
Square and 4:5 for feed posts, 9:16 for stories and short video, and wider landscape ratios for link previews and headers.
Will the platform crop it again?
It can, particularly in previews and thumbnails. Matching the intended ratio here minimises how much further it cuts.
How do I add space instead of cutting?
Use the canvas extender to pad the image out to the target ratio without removing anything from the frame.

社群媒體圖片裁切能做什麼
用預設尺寸把圖片裁成常見的社群媒體規格，並可選擇從中央、頂端或底部裁切。各平台各有比例規定，主動裁切永遠好過讓上傳表單想切哪就切哪。
什麼時候用得上
- 以平台顯示的精確比例準備貼文圖片，避免被再次裁切。
- 把橫式照片做成方形版本，同時不犧牲主體。
- 從橫式原圖產出限時動態或直式版本。
使用步驟
- 選擇圖片。
- 選擇對應平台與版位的預設尺寸。
- 選擇從中央、頂端或底部裁切。
- 執行處理並下載裁切後的圖片。
精確度、限制與實務建議
- 裁切位置才是關鍵決定：多數照片用中央，要保住人頭用頂端，前景主體則用底部。
- 平台的預覽裁法與完整檢視不同，請把重要內容遠離最外緣。
- 裁切不會憑空增加像素——小圖裁成大版位只是變成更小的圖，而不是低畫質的大圖。
常見問題
該用哪個比例？
動態貼文用方形與 4:5，限時動態與短影音用 9:16，連結預覽與頁首則用較寬的橫式比例。
平台還會再裁一次嗎？
有可能，尤其是預覽與縮圖。在這裡先裁成目標比例，能把它再裁的幅度降到最低。
我想補空白而不是裁掉怎麼辦？
請用畫布擴展工具把圖片補到目標比例，畫面內容一點都不會被移除。
