    How to resize an image

    1. Add your files: drag them into the box above, or click "Choose files".
    2. Choose a new size (a percentage or exact pixels) and click "Resize images".
    3. Download the resized images, in the same format you uploaded. Uploaded files are deleted right away, and results after 30 minutes.

    When to resize an image

    Many websites, forms and apps have size rules: a profile photo of at most 1000 pixels, a product photo of exactly 1200 by 1200, an ID photo under a certain size. Photos from modern phones are often 4000 pixels wide or more, which is far more than most uses need. Resizing makes images fit these rules, load faster and take less space, while keeping them in the same format you uploaded (JPG, PNG or WEBP).

    Tips for the best result

    About these formats

    JPG: The most common photo format. It uses compression to keep files small, and it opens everywhere, but it does not support transparency.

    PNG: A lossless image format that keeps every pixel sharp and supports transparent backgrounds. Great for screenshots, logos and graphics.

    WEBP: A modern image format from Google. It makes files much smaller than JPG or PNG, but some older apps and websites still cannot open it.

    Frequently asked questions

    Does resizing reduce quality?

    Making an image smaller keeps it sharp. Enlarging it beyond its original size makes it softer, because no new detail can be created.

    What does "Keep proportions" do?

    It keeps the width-to-height ratio of your image. If you type only a width, the height is calculated for you, and if you type both, the image fits inside that box without being stretched.

    Which formats can I resize?

    JPG, PNG and WEBP. The result keeps the same format as the file you uploaded.

    Is there a size limit?

    Files can be up to 100 MB, and the resized image can be up to 8000 pixels on each side.
