Resize Image

Resize Image scales JPG, PNG, and WebP files to any pixel dimensions or percentage. Drop in your image, type the width or height you want, and download a resized copy in seconds. The aspect ratio is locked by default so the result stays in proportion. The tool runs entirely in your browser using the Canvas API. Your image is never uploaded, which makes it safe for personal photos, screenshots of internal tools, and other content you wouldn't want sitting on someone else's server. Common uses include sizing a profile picture to fit a 400×400 avatar slot, scaling a hero image down for the web so the page loads faster, generating a 1200×630 OG image for social previews, and creating thumbnails for a portfolio page. You can also switch the output format on the way out — for example, resize a PNG screenshot and save it as a smaller JPG.
