    About Image Resizer

    Resize photos for social media, websites, email or printing. Set exact width and height, or scale by percentage, and apply the same size to many images at once.

    How to use the Image Resizer

    1. Add one or more images.
    2. Pick a size: exact pixels, a percentage, or one of the presets.
    3. Choose the format and quality, then download one file or all as a ZIP.

    Why use this tool?

    • Private: everything runs in your browser and nothing is uploaded.
    • Lock the aspect ratio to avoid stretched pictures.
    • Presets cover common sizes such as 1080 pixels for social posts and 1920 for full HD.
    • Free, with no sign-up, watermark or limits.
