FAQ

Frequently Asked Questions

What is a 3x3 grid split?

A 3x3 grid split divides a single image into 9 equal square tiles. These tiles can be uploaded to Instagram as a carousel post to create a stunning mosaic layout on your profile grid.

Does splitting reduce image quality?

No. All tiles are rendered at full resolution using the Canvas API. Each piece retains the original image quality with no compression or loss.

Can I use non-square images?

Yes. Non-square images will be split proportionally. For Instagram grid posts, square images work best. You can crop your image first using our crop tool if needed.

Are my images uploaded to a server?

No. All splitting happens entirely in your browser using the Canvas API. Your images are never uploaded anywhere and the tool works offline once loaded.

What file formats are supported?

The tool supports JPG, PNG, WebP, BMP, and GIF input formats. Output is always high-quality PNG tiles packaged in a ZIP file.
