How do I resize an image online?

Upload your image, enter the desired width and height in pixels, and click resize. The tool processes everything in your browser so your images stay private.

Will resizing reduce image quality?

Minor quality loss can occur when enlarging images. Downscaling generally preserves quality well. The tool uses high-quality resampling algorithms to minimize artifacts.

What image formats are supported?

The tool supports JPEG, PNG, WebP, GIF, and BMP formats. You can resize any of these and download the result in the same format.

Can I maintain the aspect ratio?

Yes. Lock the aspect ratio option keeps your image proportions intact. Change one dimension and the other adjusts automatically to prevent distortion.

Is there a file size limit?

Since processing happens in your browser, you can resize images of several megabytes. Very large files may take a few seconds depending on your device.
