How to Resize Images Online

Websites, marketplaces, and email clients often require specific image dimensions. Resizing keeps aspect ratio sensible and avoids stretched or cropped layouts.

Resize with Toolstik

1. Go to the Image Resizer. 2. Upload JPG, PNG, or WebP files. 3. Set a target **width** and/or **height** (leave one at 0 to scale proportionally). 4. Download resized files individually or as a ZIP.

Images are processed on your device—nothing is uploaded to Toolstik servers.

Tips

- **Downscaling** is best for performance; upscaling cannot invent detail. - Pair resizing with the Image Compressor when you need smaller file sizes too. - For print, keep higher resolutions; for web heroes, 1600–2400 px width is often enough.
