Resize images in your browser

The image resizer changes pixel dimensions without sending the original image to a server. It is useful for avatars, thumbnails, product images, blog graphics, documentation screenshots, and any image that needs to fit a specific width or height before upload somewhere else.

You can keep proportions locked for predictable scaling or set custom dimensions when a destination requires an exact size. The browser handles the resize operation locally and creates a new downloadable file, so the source image remains on your device throughout the process.

Resizing before sharing can reduce load time, trim storage use, and avoid oversized images in websites or documents. For even smaller files, combine resizing with the image compressor after dimensions are correct.

All BunnyConverter tools follow the same local workflow: choose a source file, let the browser complete the supported conversion or edit, then download the result. There is no project library to manage and no remote job to wait for. If a browser cannot read a format or does not have enough memory for a large file, the tool reports the problem locally so you can try a smaller file, a different format, or a desktop browser.

Good to know
