How to Resize Images for Social Media and Custom Sizes

Platform dimensions can change, so treat presets as convenient starting points and verify the current requirements of the destination before publishing.

Step-by-step workflow

  1. 1

    Upload the source image

    Start from the largest clean original you have.

  2. 2

    Choose a preset or custom size

    Pick the destination preset or enter the required width and height.

  3. 3

    Choose fit, fill or crop

    Fit keeps the full image visible; crop fills the frame by trimming edges; fill can add background space.

  4. 4

    Check the preview

    Make sure faces, logos and important text are not cut off.

  5. 5

    Export and verify

    Download the image and compare its dimensions with the current destination requirements.
