What is the recommended image size for Instagram Post?

Instagram Post recommends 1080×1080px with a 1:1 aspect ratio. This ensures your image displays correctly without cropping or blurring.

Will resizing reduce image quality?

Our resizer uses multi-step high-quality interpolation to maintain maximum sharpness. The result looks crisp and professional at the target size.

Can I resize multiple images?

Yes! Process as many images as you need — there are no daily limits or file count restrictions.

What formats are supported?

You can resize JPG, PNG, WebP, and GIF images. The output is saved as a high-quality PNG.

Are my images uploaded to a server?

No. All resizing happens locally in your browser. Your images never leave your device.

Can I use a custom size instead of 1080×1080?

Absolutely! The resize tool lets you enter any custom width and height. The presets are shortcuts for common platform sizes.

Why 1080×1080px for Instagram Post?

Instagram recommends 1080×1080px for feed posts. Images smaller than this get upscaled and look blurry. Images larger get compressed by Instagram's algorithm, often with visible artifacts. Uploading at the exact recommended size gives you the sharpest, most professional-looking posts in the feed.
