Need to shrink a photo for an email attachment? Resize an image for social media? Or get a graphic down to the right dimensions for your website? Just upload, set your target size, and download the result. It takes about three seconds.
Making an image smaller? You'll lose a tiny bit of quality, but honestly, you won't notice it. Making it bigger is a different story -- stretching a small image to a larger size will make it look blurry and pixelated. Always start with the largest version you have.
Uploading a 4000px wide photo when your site only displays it at 800px is like shipping a refrigerator in a semi truck. Your page loads slower, mobile users burn through their data, and Google notices -- page speed is literally a ranking factor. Properly sized images are one of the easiest performance wins you can get. Resize your images to match the actual display size and you'll see immediate improvements in load time and user experience.
Instagram posts: 1080x1080px. Instagram Stories: 1080x1920px. Facebook shared images: 1200x630px. Twitter/X images: 1200x675px. LinkedIn posts: 1200x627px. Website hero banners: 1920x1080px. Blog thumbnails: around 800x600px. Favicons: 32x32px or 16x16px. Use these exact dimensions and your images will display perfectly -- no awkward cropping, no stretched pixels, no surprises.
A few rules will save you from blurry results. Downscale whenever possible -- shrinking preserves quality far better than enlarging. Always keep the aspect ratio locked (that little chain-link icon) to avoid stretching your image into weird proportions. Do your resize in one step, not a series of small adjustments -- each resize introduces a tiny bit of quality loss, and it adds up. For the output format, stick with PNG if your image has text or sharp edges, and JPEG for photos.
