    How to use it

    1. Choose or drop your photo. You can add several at once.
    2. The tool finds the highest quality that stays under 20 KB.
    3. Check the new size under the preview, then download.

    When you need a 20 KB image

    It is one of the most common limits on Indian exam and government forms, usually for the signature, and sometimes as the minimum size for the photo. If a form rejects your photo for being too large, this page fixes it without installing anything.

    The tool saves the image as a JPG and searches for the highest quality setting that keeps the file under 20 KB. If that is not enough, it reduces the width and height a little at a time and tells you when it did.

    Getting the sharpest result

    Crop the photo to what matters before resizing: the face for a photo, the ink for a signature. A 20 KB file shared across fewer pixels looks cleaner. As an estimate, a typical photo at 20 KB is about 300 to 400 pixels wide; more detail (hair, patterned clothes, busy backgrounds) means fewer pixels at the same size.

    Questions

    Will my photo be exactly 20 KB?

    It will be just under 20 KB, usually within a few percent. Forms check that a file is not over the limit, so the tool picks the best quality that stays under it. If your form also has a minimum size, enter it in Min KB under Settings.

    Why did the width and height get smaller?

    If the photo cannot get under 20 KB at its original size, even at low JPG quality, the tool shrinks the dimensions step by step until it fits. If your form needs exact pixel dimensions, type them into Width and Height: the tool then keeps those dimensions and only lowers the quality.

    Does the form count 20 KB as 20000 or 20480 bytes?

    Websites differ, so the tool plays it safe: the file is kept at or below 20,000 bytes, which passes whether the form counts 1 KB as 1000 or 1024 bytes.

    My form says "between 10 KB and 20 KB". Which page should I use?

    Use the 10 KB to 20 KB page. It sets both a minimum and a maximum, so the file cannot come out too small either.

    Will a 20 KB photo look blurry?

    A passport-style photo at about 350 × 450 pixels still looks sharp at 20 KB. A large landscape photo squeezed to 20 KB will lose detail, because there is less data to hold it. Cropping to just the face before resizing gives the best result.

    Is my photo uploaded to a server?

    No. The resizing runs inside your browser with JavaScript, so the image never leaves your device. Once the page has loaded, resizing keeps working even if you go offline.
