What is this SNS image resizer?
A free, browser-based tool that resizes and crops your images to the exact dimensions each social platform expects — X (Twitter), Instagram, Facebook, LinkedIn, and OGP share images. Upload one or many images, pick the presets you need, choose cover (crop) or contain (pad), and download everything as a single ZIP. All processing happens locally in your browser, so your images are never uploaded.
How to use it
- Upload one or more images on the left (drag & drop or click).
- Select the SNS presets you need — you can pick several at once.
- Choose a fit mode (cover crops, contain pads) and an output format (PNG / JPG / WebP).
- Press “Resize & download zip” to get every image at every selected size.
Common use cases
- Preparing one campaign visual in every platform's required size at once.
- Creating an OGP image so links share cleanly on social media.
- Batch-resizing product photos for an Instagram or LinkedIn post.
