About this tool
Resize any image to exact dimensions — by width, height, or both (with fit or crop) — entirely in your browser. Batch mode handles dozens at once; nothing uploads, so it works with private images and huge files.
How to use the Image Resizer
- Drop images or choose files.
- Set target width/height and fit mode.
- Download each result or all at once.
Frequently asked questions
Will resizing reduce quality?
Downscaling with the Lanczos-style canvas filter keeps images sharp; upscaling beyond ~2× will soften.
What sizes should web images be?
No wider than their largest display size — typically 1200–1600px for full-width, 800px for in-content.
