Instagram Post Resizer

Q: What size is a Instagram Post?

A Instagram Post is 1080×1080 pixels, a 1:1 square ratio. Sizing your image to that exactly prevents Instagram from cropping or scaling it in ways you didn't intend.

Q: How do I resize my photo for Instagram?

Drop your image into the tool above, drag the crop box to frame the subject, and download. The output is locked to 1080×1080 pixels, ready to upload.

Q: Will my image lose quality?

No meaningful loss — the tool uses high-quality resampling. Start with an image at least as large as the target so downscaling keeps it crisp.

Q: Is anything uploaded to a server?

No. The crop and resize run locally in your browser, so your photos stay private and nothing is stored on our end.

Q: Is there a watermark?

No watermark, and no limit. The tool is free because it runs entirely on your device.

⚡ Try with a sample photo

Crop and resize any photo to the exact Instagram Post size — 1080×1080 pixels — in your browser, free and without a watermark. That's a 1:1 square frame, the dimensions Instagram expects so your image isn't stretched, zoomed, or cut off. Drop in your image, position the crop, and download a perfectly-sized Instagram Post.

The correct Instagram Post size

Instagram Post images should be 1080×1080 pixels (1:1). Upload something the wrong shape and Instagram will auto-crop it — often cutting off faces, logos, or text. Sizing it yourself to 1080×1080 pixels first means what you see is exactly what gets posted.

Crop to fill or fit

Most source photos aren't already 1:1. The tool lets you drag to choose which part of the image fills the 1080×1080 pixels frame, so the important subject stays centered. High-quality resampling keeps the result sharp, and the export matches 1080×1080 pixels to the pixel.

Free, private, no watermark

Everything happens on your device — nothing is uploaded, and there's no account or watermark. Making a full set of platform assets? Resize the same image for Instagram, a Facebook post, or a YouTube thumbnail in the same tool.

Common ways people use it

Instagram content

Post a Instagram Post that fills the frame cleanly at 1080×1080 pixels instead of letting the app crop it for you.

Brand consistency

Keep every Instagram asset at the same 1080×1080 pixels spec so your profile and feed look intentional.

Repurposing one photo

Take a single hero image and crop it precisely for Instagram Post without redesigning it from scratch.
