How to resize images for social media

1

Choose your image

Upload or drop a photo, graphic, or logo. You can also paste an image from your clipboard or load an image URL that allows browser access.

2

Pick sizes and adjust the fit

Choose a platform preset. Crop to fill the frame, or fit the whole image with padding. Drag the image to adjust each crop, or use the sliders. Include the sizes you want in your ZIP.

3

Download your resized images

Save the preview as PNG or JPG, or download your selected sizes together in a ZIP. Everything is processed in your browser.

Common social media image sizes

Start with these presets, then check the platform preview before publishing. Profile photos and banners can be cropped differently on phones and desktop.

Crop for impact. Fit to keep every detail.

Crop to fill works well for photos with room around the subject. Move the crop to keep faces, products, and text visible. Fit entire image is useful for logos and finished graphics where cutting an edge would lose information.

Neither mode stretches your image. PNG keeps transparent areas; JPG fills them with your chosen background color.
