How the resize and crop works
Each social platform shows images in a particular shape, and a photo with different proportions gets cropped or padded. This tool prepares the image in advance. You pick a preset size, and it scales your image until it fully covers that shape, then centers it and trims whatever sticks out. The method is often called cover fit.
The presets are Instagram Post (1080 by 1080), Instagram Story (1080 by 1920), Facebook Cover (820 by 312), Twitter/X Post (1600 by 900), LinkedIn Banner (1584 by 396) and YouTube Thumbnail (1280 by 720). The output is always exactly the preset width and height in pixels, saved as a PNG.
When a preset resize is useful
Uploading a mismatched image often leads to platform cropping you did not choose, such as a face cut off or a banner with the key text missing. Preparing the picture yourself gives a result you can see before posting.
It is also handy when one photo has to be reused across several channels, because you can export it at each size in turn. For a general resize to your own width and height, see the Image Resizer, which is better when you need a custom size or want to keep the whole picture.
How to resize an image for social media
- Drop an image onto the upload area, or click to choose one. Any image type your browser can open should work.
- Pick a preset from the drop-down list that appears.
- Check the Original picture on the left, then click Generate. The Result on the right shows the new size in its label.
- If it looks right, click Download to save the PNG.
The file is named after the preset, in lowercase with hyphens, such as instagram-story.png. Everything happens in your browser, so the image is not uploaded anywhere.
What to watch for
The crop is always centered, and there is no way to move or zoom it. If your main subject sits near an edge, it may be cut off, especially with very wide shapes such as the LinkedIn Banner or Facebook Cover, where a lot of height is trimmed from a normal photo. Choose or edit a source image with the subject near the middle.
If your image is smaller than the preset, the tool enlarges it to cover the space, which can make it look soft or blurry. A photo that already has similar proportions will lose the least. If you change the preset after generating, click Generate again, since the displayed result does not update on its own and the download name follows the currently selected preset.
Once an image is loaded there is no button to replace it, so reload the page to start with a different file. Output is PNG only, so files can be larger than a typical JPG, and the Image Compressor can help if a platform has a size limit. Platform sizes change over time, so check current guidance for each service.
