Social Media Image Sizes: Stop Awkward Auto-Cropping

Difficulty: Beginner • Time: 2 min • Great for: WeChat, Weibo, Instagram, X

Crop avatars & covers right the first time!

Precise platform crops, 100% local processing.

You picked the perfect avatar, then the platform cropped it into half a face. You designed a beautiful cover, and the feed only shows a thin slice of it. The fix is simple: pre-crop to the platform's display ratio. This tutorial shows you how to do it locally with Web PSEditor, so what you crop is exactly what gets displayed.

Quick Size Reference

Avatars & square feed posts: 1:1 (800×800 px or larger); page covers: roughly 16:9 (commonly 1200×628); stories & short-video covers: 9:16. Pre-cropping to these ratios keeps platforms from cutting randomly.

The Two Crops You Need Most

Step-by-Step in the Editor

Step 1: Crop the Composition

Open your photo, pick the Crop tool in the left toolbar, set the target ratio (e.g. 1:1) and confirm. Keep the subject centered or on a third line so it survives compression.

Step 2: Set Exact Pixels

Click Image → Image Size and enter the target pixels (e.g. 800×800). Keep "keep aspect ratio" enabled to avoid distortion.

Step 3: Export & Upload

File → Save As as JPG (quality 85+). Check the live display after uploading and fine-tune the crop if needed.

💡 Making one sized version per platform beats squeezing one file everywhere — local processing takes seconds.
