Why size matters

Upload at the wrong dimensions and the platform crops or compresses it — cutting off faces, blurring text, or adding bars. Posting at the native size keeps your image sharp and fully visible.

The sizes (pixels)

  • Instagram — square 1080×1080, portrait 1080×1350, story/reel 1080×1920.
  • YouTube — thumbnail 1280×720, channel banner 2560×1440.
  • LinkedIn — shared image 1200×627, profile banner 1584×396.
  • X (Twitter) — in-stream 1600×900, header 1500×500.
  • Facebook — shared post 1200×630, cover 851×315.

How to resize to these

  • Open the Image Resizer and enter the exact width and height.
  • If the aspect ratio doesn't match, use the Image Cropper first to frame it, then resize.

Keep the file small too

After resizing, run the image through the Image Compressor so it stays sharp without being oversized.

Everything stays on your device
