Bulk Image Resizer
Enter a width, a height or a percentage. Keep the aspect ratio locked to avoid distortion, and switch off upscaling when you only ever want to shrink.
Drop images here, or browse your files
JPEG, PNG, WebP, AVIF and BMP. Up to 200 images per batch, 50 MB per file.
Files are read locally by your browser and are never uploaded to a server.

Good to know
- With the aspect ratio locked, entering one dimension derives the other.
- Upscaling is off by default so images are never enlarged by accident.
- Oversized results are clamped to safe canvas dimensions to avoid browser limits.
Your files stay on your device
This tool decodes and re-encodes images inside your browser using the Canvas API and Web Workers. Nothing is uploaded, and there is no server that could receive your files. Closing the tab discards everything.
