Social Media Image Resizer

Every network crops images to its own shapes: a Facebook cover is a wide strip, an X header is 3:1, a Pinterest Pin is tall, a podcast cover is a big square. This resizer holds the current sizes for the main platforms in one list, makes the exact pixel size you pick — or every size for one platform at once — and either crops to fill the frame or fits the whole image on a blurred or coloured background. The table below the result shows all sizes and where each one comes from. Your images never leave your device.

How to use this tool

1. Choose one or more images.
2. Pick a size from the list, a whole platform pack, or enter a custom width and height.
3. Choose to crop (fill the frame) or to fit the whole image on a blurred or solid background.
4. When cropping, choose the part to keep.
5. Download the images, or all of them as a ZIP.

Formula

crop scale = max(W ÷ w, H ÷ h); fit scale = min(W ÷ w, H ÷ h)

w × h is your image and W × H the target. Cropping covers the frame and trims the overflow on the side you did not keep; fitting shows the whole image and fills the empty space. The ratio is shown in whole numbers, or as a decimal such as 2.7:1.

Example

A 1600 × 1200 photo made into a Facebook Page cover (851 × 315) with “crop” is scaled by max(851 ÷ 1600, 315 ÷ 1200) = 0.532 to 851 × 638, and 161 px are trimmed from the top and bottom. The same photo as a Pinterest Pin (1000 × 1500) is scaled by 1.25 to 2000 × 1500 and 500 px are trimmed from each side.

Which sizes are official?

Instagram, Facebook, X, LinkedIn, YouTube and Apple Podcasts publish the sizes marked with their help pages in the table. Others, such as the TikTok cover, Pinterest Pin or Twitch banner, are sizes creators commonly use because they match how the platform shows the image; they are marked “Common practice”.
