    Resize photos to exact pixels

    Use the Image Resizer to bring an image to a specific width, shrink a photo to the size a form requires, or fit it exactly into a space on your website. Enter width and height in pixels or scale by percentage.

    Social media presets

    Popular sizes such as an Instagram post (1080×1080), Instagram story (1080×1920), YouTube thumbnail (1280×720), X post and Facebook cover are one click away. Keep the aspect ratio locked to avoid squashed or stretched images, or choose to crop to fill or fit inside with a background.

    High quality and private

    Resizing uses high-quality resampling in your browser and your photos are never uploaded. Shrinking a large photo also reduces its file size considerably.

    How to use Image Resizer

    1. Choose the image or images to resize.
    2. Enter a new width and height, use a percentage or pick a social preset.
    3. Keep the aspect ratio locked or choose a resize mode.
    4. Download the resized images.

    Why use this tool?

    Prepare correctly sized images in seconds without installing software, and batch-resize a whole folder of photos to the same size.

    FAQ

    Will enlarging an image ruin quality?

    Making an image larger than its original doesn't add detail and can look blurry. For better upscaling try the AI Photo Enhancer.

    What is aspect ratio and why lock it?

    It is the ratio of width to height. When locked, you change one side and the other is calculated, so the image isn't distorted.

    Does resizing also reduce file size?

    Yes. Fewer pixels means a noticeably smaller file.
