Resize an Image for Social Media Presets
Nujiz Social Media Image helps prepare an image using preset dimensions for common social posts, stories and other platform-oriented formats. You select the required dimensions and choose how the source image should fit before a new JPEG is created.
The tool supports two main fitting approaches: keeping the complete image visible where possible or filling the entire target frame, which can crop outer areas when the source and target aspect ratios differ.
How to Use the Tool
- Choose an image.
- Select the preset size required for your use.
- Choose how the image should fit the target frame.
- Review the resulting composition.
- Create and download the JPEG at the selected dimensions.
How It Works and Its Limitations
If the source aspect ratio differs from the selected preset, Cover may crop some outer content in order to fill the entire frame. Contain is more suitable when keeping the complete source visible is more important than filling every edge.
Frequently Asked Questions
Does the tool actually change the image dimensions?
Yes. A new image is created using the dimensions of the selected preset.
What is the difference between Contain and Cover?
Contain keeps the full source visible where possible, while Cover fills the frame and can crop outer areas.
What format is the result?
The current implementation exports the prepared image as JPEG.
Does this social image tool use AI?
No. It uses standard canvas resizing and image fitting.
Is image processing performed locally?
Yes. The social-media image is prepared directly in your browser.
