What does this tool do?
Make It Square adds borders to your photos so they fit Instagram's square format without cropping. You can adjust the border size and colour.
What file formats are supported?
PNG, JPG, and HEIC. HEIC is the default format for iPhone photos, so you can upload straight from your camera roll.
Are my photos private?
Yes. Your photos never leave your device. All processing happens directly in your browser — nothing is uploaded anywhere. There are no cookies, no personal data collected, and no account required.
Does it work offline and on mobile?
Yes to both. After your first visit, everything is cached locally — turn off WiFi and it still works. On mobile, you can add it to your home screen for an app-like experience.
Can I process multiple images?
Yes. You can select or drag up to 30 images at once. Use the arrows to navigate between them, and download will create a zip file with all processed images.
Can I paste images?
Yes. Just press Cmd+V (Mac) or Ctrl+V (Windows) to paste an image from your clipboard.
Can I copy the result?
Yes. Click Copy to put the processed image on your clipboard, ready to paste anywhere.
Does it remember my settings?
Yes. Your border size, colour, and quality preferences are saved in your browser and restored on your next visit.
Are there keyboard shortcuts?
Yes. Cmd/Ctrl+O to open files, Cmd/Ctrl+S to save, Cmd/Ctrl+C to copy, Escape to reset. Arrow up/down adjusts border size (hold Shift for larger steps). Left/right arrows navigate between images in a batch.
Do I need to create an account?
No. There's no sign-up, just open the page and use it.
Is it free?
Yes, completely free. No premium tier, no hidden costs.
What are the export size options?
Original (full resolution), Large (2000px), Instagram (1080px — the maximum size Instagram displays), and Small (800px).
Why does the preview look slightly different in Chrome or Firefox?
Chrome and Firefox use different image scaling algorithms than Safari, which can cause thin lines or fine details to look slightly softer in the preview. This is just a display issue — your downloaded image is always full quality and unaffected.
Is this open source?
Yes. The code is available on GitHub under the MIT license. You can inspect it, fork it, or contribute.
