Build a 1080 by 1080 Square Post Image
Turn any photograph into the square format feed posts use, with an optional caption across the bottom.
About the Social Media Post Creator
Square is the shape that survives contact with a social feed most reliably, and 1080 by 1080 pixels is the resolution platforms render it at. This tool fixes the canvas to those dimensions and places your picture into it. Choosing fill crops the image so it covers the square completely — the usual choice for a portrait or near-square source. Choosing fit places the whole image inside and pads the remaining strips with a background colour, which is how you keep a wide landscape photograph intact rather than losing its ends.
A caption can be overlaid near the foot of the square, in a colour you choose and at a size expressed as a percentage of the width. It carries a shadow so it holds up over a detailed photograph. Output is JPG by default or PNG if you prefer. Everything is assembled on your machine, which matters when the photograph in the post shows people who agreed to appear on your feed and nowhere else.
Key Features
- Fixed 1080 pixel square: The canvas matches what feeds display, so the post is not resampled awkwardly after upload.
- Crop or pad: Fill covers the square by cropping, while fit keeps the whole photograph and pads the sides with colour.
- Caption with shadow: Overlaid text sits low in the square with a soft shadow so it stays readable against the image.
- Colour control: The padding colour and the caption colour are set separately, so the post can follow a house style.
- Choice of export format: JPG keeps the file small for upload, PNG avoids compression on graphic-heavy designs.
How to Use the Social Media Post Creator
- Add the photograph you want to post.
- Select fill to crop it square, or fit to keep it whole with coloured padding.
- Set the background colour, then add and style a caption if you need one.
- Export as JPG or PNG and upload it to your feed.
How It Works
The canvas is created at 1080 by 1080 and painted with your background colour first, so padding is already in place before the image lands. The scale factor is chosen from the two axes — the larger for fill so nothing is left uncovered, the smaller for fit so nothing is lost — and the picture is centred with high-quality resampling. Caption text is drawn in a bold face limited to ninety percent of the width, with horizontal compression rather than wrapping if it runs long. Worth anticipating: a wide landscape photograph in fill mode loses a substantial slice from each side, so a subject positioned to one side of the frame can vanish entirely. Crop it deliberately first when the composition matters.
When You Need It
A junior football club posts a match round-up, and the photograph shows children on the pitch. The parents signed a form permitting images on the club's own accounts, which is a narrower permission than it sounds — it does not extend to the picture being uploaded to a design website that keeps a copy on its servers. Building the square locally keeps the club inside the consent it actually holds. Small retailers producing product squares and venues announcing events prepare posts the same way, with less at stake but the same workflow.
