Social Media Resizer
Generate platform-specific image sizes with live crop control.
Why use Social Media Resizer?
The resizer is built for social publishing. Start from one source image, generate common platform sizes and adjust the crop before downloading each version or the full ZIP.
Create several social variants from one upload.
Adjust the crop instead of trusting platform auto-cropping.
Download one size or the whole package at once.
Common use cases
Create a square post and a story from one campaign image.
Prepare header art for LinkedIn, X and Facebook.
Build thumbnails and vertical assets from the same source.
FAQ
Does the tool stretch my image?
No. It uses a cover-style crop so the target dimensions fill correctly without stretching.
Can I download every generated size at once?
Yes. The bulk download packages all generated sizes into one ZIP file.
What if I need a custom size?
Use Aspect Ratio Helper for planning and combine Crop or Convert when you need a workflow outside the presets.
