About image resizing
This tool resizes an image to an exact width and height. Choose a social media preset, such as OpenGraph at 1200 by 630 or Twitter Banner at 1500 by 500, or enter a custom size.
The Inside fit keeps the aspect ratio and fits the image in the box. The Fill fit stretches the image to the exact size. Lanczos3 gives the sharpest result for a photo. Nearest keeps hard pixel edges for pixel art. The tool does not enlarge a small image by default, so the result does not get blurry.
Choose a file. Set the size and the output format, then select Process. WebP gives a small file for the web. PNG keeps every pixel.
The resize runs in your browser for a WebP, JPEG, or PNG output, so no image data leaves your device. An AVIF output, or a file that your browser cannot decode, runs on the server with Bun. The server holds the file in memory and does not store it.
