Social Media Image Resizer
Crop and resize an image to fit Instagram, X/Twitter, Facebook, LinkedIn, or YouTube dimensions. Everything runs locally in your browser.
Resize images for every social platform
Each social network crops or rejects images that don’t match its expected dimensions — an Instagram post is a 1:1 square, a YouTube thumbnail is 16:9, and a LinkedIn banner is a wide 4:1 strip. This tool locks the crop box to the exact aspect ratio and pixel size the selected platform expects, so you can drag to frame the shot and export a PNG sized precisely right, without guesswork. Use the zoom slider to crop in tighter, or drag the crop box to reposition it over the part of the image you want to keep. Nothing is uploaded — the crop and resize happen locally on the Canvas API. For a general-purpose crop with custom aspect ratios, try the Image Cropper, or the Image Resizer for resizing without cropping.
Private & free — this tool runs entirely in your browser.
