Frequently asked questions

What image sizes does the Instagram Image Resizer support?

This tool supports the most common Instagram formats: Square (1080×1080px, 1:1); Portrait (1080×1350px, 4:5); Story / Reel (1080×1920px, 9:16); Profile (320×320px, 1:1).

Is my image uploaded to a server?

No. Everything happens locally in your browser using the HTML Canvas API. Your image is never sent to any server — it never leaves your device.

What file formats can I upload?

You can upload PNG, JPEG, or WebP images (any format your browser can display). The exported file is always a PNG, which preserves quality without re-compression artifacts.

How does the crop work?

The tool uses a center-cover crop: it scales your image until it fills the target dimensions, then trims evenly from the edges to hit the exact pixel size. The center of your image is always preserved, so the main subject stays in frame.

Is this Instagram Image Resizer free?

Yes. It is completely free, needs no sign-up, and runs entirely in your browser.
