About Resize Image
Get images to exactly the size you need. Resize by width and height in pixels with the aspect ratio locked, scale by a percentage, or pick a preset for Instagram posts and stories, Facebook and LinkedIn covers, YouTube thumbnails, passport photos, favicons and HD screens. Choose JPEG, PNG or WebP output and the quality, then download. Resizing runs in your browser, so your images are never uploaded.
