Applies to JPG and WebP. Higher means a larger file.

    How resizing keeps the detail

    Shrinking a big photo in one jump can leave jagged edges. When the new size is less than half the old one, this tool halves the image in steps and averages neighboring pixels each time, then makes the last small adjustment. The result looks smoother than a single big reduction.

    Good to know

    • Your images are processed in your browser and never uploaded.
    • Enlarging is possible, but a resizer cannot invent detail that was never in the photo.
    • The output is limited to about 16 megapixels so phones do not run out of memory.
    • Transparent PNG areas turn white when you save as JPG. Save as PNG or WebP to keep transparency.

    Choosing a size for the web or a document

    Start from where the photo will be used. For a web page or a message, a smaller width often loads faster and is easier to send; for a document you will print, keep more pixels. If you only fill in one side, the other side follows so the photo does not stretch.

    Questions

    Are my photos uploaded?

    No. Resizing happens inside your browser. Nothing is sent to a server, and the tool keeps working offline after the first visit.

    How do I resize to an exact width?

    Choose Pixels, type the width, and leave the height empty. The height is calculated to keep the same proportions.

    Can I resize many images at once?

    Yes. Add up to 50 images, choose one setting, and each image is resized with it. Download them one by one or all together as a ZIP.

    What does quality do?

    Quality applies to JPG and WebP. A higher number keeps more detail and makes a larger file. PNG is lossless, so it has no quality setting.

    Will my phone photos come out rotated?

    No. The tool reads the orientation stored in the photo and saves it upright.

    What width should I use for a website photo?

    Use the width the page will show it at, or a little larger, rather than the full camera size. A photo shown small on a page does not need thousands of pixels wide.

    Will resizing make a blurry photo sharp?

    No. Resizing keeps the detail that is already there, and enlarging cannot add detail. Start with the sharpest original you have.
