What size should an Instagram post image be?

1080×1080px for a square post, 1080×1350px for a portrait post, and 1080×1920px for a Story or Reel — all included as presets in this tool.

Is my photo uploaded to a server?

No — the resize and crop happen entirely in your browser using the Canvas API. Your photo never leaves your device.

Can I crop off-center?

Yes — use the X/Y focus sliders to move the crop point before exporting, so the important part of the photo stays in frame.

Yes, completely free with no signup and no watermark.
