How to Resize Photos to 20KB
When preparing photos for digital forms, membership accounts, or online profile submissions, file uploaders often specify compact file thresholds such as 20 KB. High-resolution phone cameras produce pictures that can be several megabytes in size, making optimization necessary before uploading.

The compression engine runs multiple quality passes in milliseconds to find the highest fidelity setting that fits under your 20 KB target.
Take a 3 MB smartphone selfie, crop to a 3:4 headshot, and compress to 20 KB. Or convert a heavy PNG scan into a lightweight JPG under 20 KB.
Optionally specify physical measurements in centimetres or millimetres with selectable 200, 300, or 600 DPI resolution settings.
All image processing takes place exclusively in your web browser. Your private portraits never leave your computer or mobile phone.
Tip: Frame your face comfortably within the crop handles before downloading. Having the background evenly lit helps achieve sharper visual clarity at small file sizes.
