Social Media Image Resizer
Create correctly sized posts, stories, covers, thumbnails and profile images with ready-made presets.
One image, every platform
Select a preset, choose whether the image should fill the frame or fit completely, and export a ready-to-publish file. The canvas preview updates locally and your source image is not uploaded.
Resize images for social media without guessing dimensions
Social platforms use different aspect ratios for square posts, portrait posts, stories, thumbnails, covers and profile images. This tool gives you ready-made dimensions and a visual preview so you can prepare one source image for a specific placement without manually calculating the canvas size.
Use cover when the destination must be completely filled and some edge cropping is acceptable. Use contain when the full image must remain visible, even if padding is needed. For brand graphics, check important text and logos near the edges before downloading because platform interfaces can overlay controls or crop previews differently across devices.
Common social image workflows
Posts and stories
Start with the platform preset, preview the crop, then export a clean JPG, PNG or WebP copy.
Thumbnails
Use a landscape preset for video thumbnails and keep faces or headline text away from extreme edges.
Reuse one source
Create separate outputs for square, portrait and landscape placements instead of stretching the same image.
Social media image resizer FAQ
Does resizing change the original file?
No. The tool creates an exported copy; the source image remains unchanged.
Should I use JPG, PNG or WebP?
JPG is practical for photographs, PNG is useful when transparency or sharp graphics matter, and WebP can reduce file size when the destination accepts it.
Will every platform display the image exactly the same?
No. Apps can crop previews or overlay interface elements differently, so keep important content away from the outer edges.
