Resize images to social media sizes in one pick
This social media image resizer holds the commonly published sizes for social posts and resizes your image to the one you pick: square posts, stories and video thumbnails among them. Choose an image, select the platform size, and download a copy made to that specification instead of measuring and typing dimensions by hand. The result downloads at exactly the dimensions you selected.
Skip the size charts
Every platform crops uploads that do not match its preferred dimensions, often at the worst place. Preparing the image at the published size first keeps your subject framed as intended and avoids surprise crops. Presets suit routine publishing, where the same handful of sizes covers a whole content calendar across profiles and platforms.
Good to know
The sizes are the commonly published platform sizes at the time they were added, and platforms do change their specifications. If a platform rejects or re-crops an image, check its current guidance; the preset cannot know about a change made after it was recorded here.
Frequently asked questions
How is this different from the Image Resizer?
The Image Resizer takes any exact width and height you type, suiting custom slots. This tool offers ready-made platform sizes picked from a list. Use presets for standard posts and stories; use the exact resizer for custom dimensions.
What if my photo's shape differs from the chosen size?
The image is resized to the selected dimensions, so a photo with very different proportions can look stretched. For an important post, compare the result before publishing, and consider cropping first to control what is kept.
Are my images uploaded anywhere?
No. Files are processed in your browser and never sent to the site's server. The resize is done on your device and the finished image downloads from your browser, keeping your photos private throughout.
