What this image resizer does
Set a target width and optional height, keep the original aspect ratio if needed, and resize multiple images locally in your browser.
Input
JPEG, PNG or WebP images plus target dimensions.
Output
Resized image files in the format you choose.
Example
Resize product images from 3,000 px wide to 1,200 px before uploading them to a website or content management system.
Privacy
Processed locally in your browser — your working input is not uploaded by this tool. The current implementation uses browser APIs for processing. If Tools Brave later adds a server-powered version of this utility, the page will disclose that change before processing begins.
Limitations to know
- Upscaling cannot recreate detail that is missing from a small source image.
- Very large output dimensions can exceed browser canvas limits.
- Repeated lossy re-encoding may reduce image quality.
