Resize images for Instagram’s 1080×1440 post size

Instagram’s current feed post is 1080×1440. Resize locally, optionally compress.

Instagram’s current recommended feed post is 1080×1440 (3:4). Square 1080×1080 still works. 4:5 (1080×1350) is the older portrait size. Stories remain 1080×1920.

Image Resize runs in the browser. Preset “Instagram post 3:4” is the default. You can also set exact pixels, a percentage, or other presets (square, 4:5, story, YouTube-style HD). Optional compression writes a smaller JPEG/WebP.

Steps

  1. Drop JPG, PNG, or WebP files.
  2. Keep Preset → Instagram post 3:4, or pick another size.
  3. Optional: turn on compress and set quality.
  4. Resize. Several images download as a ZIP.
