About Instagram Post Resizer
An Instagram square post uses 1080×1080 pixels. “Fill and crop” fills the frame and trims the edges; choose which side to keep. “Fit on blurred photo” shows the whole picture with a soft blurred copy behind it, a popular look for photos of a different shape. Several photos can be resized at once.
Your files are read in this browser tab and never uploaded. Nothing is stored after you close the page, and there is no size limit beyond your device’s memory.

What size is an Instagram square post?
1080 × 1080 pixels, the size this tool exports. Platforms sometimes change their recommendations, so check their help pages for anything critical.

Choose “Fill and crop” and pick which side to keep, or “Fit with background” or “Fit on blurred photo” to show the whole picture with space around it.
