# Social Media Image Resizer

> A free browser-based crop and resize tool with more than 28 common presets for nine social platforms.

## What it does

- Includes common post, story, thumbnail, header, banner, profile, and pin presets.
- Supports crop, zoom, rotation, and preview before download.
- Accepts JPG, PNG, and WebP input and can preserve transparency with PNG output.
- Processes the image in the browser session without a Solnk signup.

## Limits and interpretation

- Presets are practical starting sizes, not a guarantee that every platform surface uses one fixed crop.
- Platforms can crop differently by device, placement, or interface and can update recommendations.
- Keep important text and subjects away from edges and review the final upload preview in the destination app.
- The tool changes pixel dimensions; it does not improve source detail or guarantee platform compression quality.

## Cost and access

The tool is free to use and does not require a Solnk account. Use the [interactive tool](https://solnk.com/tool/image-resizer) to perform the task.
