Social Media Image Fitter
Choose a post format and export an image at exact dimensions by cropping or adding padding.
This image never leaves your browser.
About this tool
Fit images to common square, portrait, story, landscape card, and video thumbnail dimensions entirely in your browser. Choose a full crop or preserve the whole image with colored padding, then download the exact-size result.
Crop mode fills the destination and removes excess areas from the center. Fit mode preserves the entire image and fills unused space with the selected background color.
Presets are common examples. Platform requirements can change, so width and height remain editable. Also check the final post screen for interface elements that may cover text or faces.
Images are processed only inside your browser and never uploaded. Images longer than 4,096 pixels are reduced for responsiveness. Export as PNG or JPEG.
