How to resize an image

  1. Upload the image you want to resize.
  2. Choose a preset - Instagram square or story, YouTube thumbnail, X header or post, LinkedIn banner, square avatar or Full HD - or type an exact width and height in pixels.
  3. Keep the aspect-ratio lock on to avoid stretching, or unlock it to set both sides freely. You can also scale by percentage.
  4. When the new shape differs from the original, choose Crop (cover) to fill the frame, Fit (pad) to add a background color around it, or Stretch.
  5. Preview the result and download it.

Common social media image sizes

Instagram square posts are 1080 × 1080 px and stories/reels are 1080 × 1920 px. A YouTube thumbnail is 1280 × 720 px. An X (Twitter) header is 1500 × 500 px and an in-feed image works best at 1600 × 900 px. LinkedIn profile banners are 1584 × 396 px. The presets in this tool fill these in for you.

Crop, fit or stretch?

Crop (cover) scales the picture until the frame is full and trims whatever overflows - best when the subject is centred. Fit (pad) keeps the whole picture and fills the empty space with a colour you choose, which is ideal for product shots and logos. Stretch forces the image into the new shape and will distort it, so use it only when the proportions are already close.

Private by design

Resizing happens on an HTML canvas inside your browser. Your photos are not uploaded, so you can resize personal pictures and client work without handing them to a third-party server.

Frequently asked questions

Will resizing make my image blurry?

Making an image smaller keeps it sharp. Enlarging beyond the original size cannot add detail, so heavy upscaling will look soft.

How do I resize without stretching?

Keep the aspect-ratio lock on, or use Crop (cover) or Fit (pad) when the target shape is different from the original.

Does resizing reduce the file size?

Yes - fewer pixels means a smaller file. For the smallest result, resize here and then run the image through the Image Compressor.
