Resize Image to 1:1
Make a 1:1 ratio picture for avatars, social posts and marketplace listings. Cover crops the outside edges; Fit keeps the whole image and adds padding.
Quick answer
Upload a photo, keep the 1:1 ratio and choose Cover to crop it into a square or Fit to pad the canvas so the whole image stays visible. Neither mode stretches the subject. Download the square avatar or marketplace image directly — processed locally, free, no account.

About Resize Image to 1:1
Square 1:1 assets are the currency of avatars, marketplace listings and social grids. Profile fields, catalog thumbnails and post previews frequently demand a square file, and stretching a rectangle to fit distorts faces and products immediately. This tool reshapes the canvas to 1:1 while keeping the subject's proportions untouched.
Choose Cover when the center of the photo is the subject: the square is filled by cropping the longer sides. Choose Fit when nothing may be lost — product shots with tight margins, screenshots, diagrams — and the tool pads the canvas so the entire image stays visible. The preview shows the exact output dimensions before you download.
For consistent catalog or grid results, start from images framed with the subject near the center, because Cover keeps the middle composition when it crops. A frame added afterwards with Add Border to Image can visually even out squares that were padded rather than cropped.
Common square image sizes
The square sizes platforms and stores actually request. Start from a source at least as large as your target so the export stays sharp.
| Size in pixels | Typical use |
|---|---|
| 1080 × 1080 | Instagram and Facebook square posts |
| 1024 × 1024 | iOS app icon submission; large profile and product art |
| 800 × 800 | Marketplace listings and catalog grids |
| 512 × 512 | Google Play store icon |
| 400 × 400 | Profile photos on X and LinkedIn |
This tool reshapes the canvas to 1:1 at your source resolution rather than scaling to a fixed size, so check the preview dimensions before downloading.

Frequently asked questions
Will my image be stretched?
No. Cover crops the image to fill the square, while Fit adds background so the entire image remains visible.
Are my images uploaded?
No. Images are processed locally in your browser and are not uploaded.
What image formats are supported?
JPG, PNG and WebP inputs are supported, with JPG, PNG and WebP output options.
When should I choose Fit instead of Cover?
Choose Fit when every part of the image matters, such as diagrams, documents or product photos with tight margins.
How do I make an image 1:1?
Upload the image, keep the 1:1 ratio selected and choose Cover or Fit. The browser creates a square canvas without changing the proportions of the subject.
What size should an Instagram square post be?
1080 × 1080 pixels. Instagram displays square posts at up to 1080 px wide and scales anything larger down, so export at that size or bigger and let the platform do the shrinking.
