Resize Photo to 20KB
Resize a photo to under 20KB, free. Reduce a JPG or PNG image to the exact limit your form asks for. It runs in your browser, so nothing is uploaded.
How it works
- Choose your photo. It opens on your own device and is not sent anywhere.
- The tool finds the best JPG quality that stays under 20KB, and only shrinks the pixel size if quality alone is not enough.
- If your form asks for exact pixels or a minimum size, open "More options". The photo is cropped from the centre to match the pixel size.
Tips for a 20KB limit
This is a very tight limit. Expect the pixel size to come down, so crop tightly before you start: every bit of background you remove is spent on the part that matters. Avoid patterned or outdoor backgrounds, and do not expect small printed text in the picture to stay readable.
What fits in 20KB
A rough guide to the largest pixel size a photo can keep at 20KB. Plain backgrounds fit more pixels than busy ones. If yours is larger, the tool lowers the pixel size so it stays clean instead of turning blocky.
| Quality | Largest size |
|---|---|
| Sharp, holds up when zoomed in | 230 × 310 px |
| Clear, fine for most forms | 280 × 370 px |
| Acceptable when shown small | 390 × 520 px |
Getting a clear photo at a small size
Start from a sharp, well-lit picture against a plain background, and crop close to the head and shoulders before resizing. Less background means more of the allowed size is spent on your face.
Questions
Is my file uploaded to a server?
No. All the work happens inside your browser. The file never leaves your phone or computer.
My form asks for a size between two numbers. Will this work?
Yes. Open "More options" and type the lower number as the minimum size. The result normally lands just under your limit anyway, and if the picture alone comes out below the minimum, the file is padded up to it without changing how it looks.
What format is the result?
JPG (also written JPEG), which is what almost every application form accepts. PNG and WebP pictures are converted for you.
Will the photo look blurry?
The tool keeps the highest quality that fits under your limit. A very small limit on a large, detailed picture will lose some sharpness.
Does it work on a phone?
Yes. It works in the browser on Android and iPhone, with nothing to install.
