Compress Passport Photo to Exact 20KB Online
Need a file of exactly 20 KB? Drop any photo here, set the target slider to 20 KB, and download a sharp JPG that fits the limit perfectly.
1. Adjust your photo
Turns ruled notebook paper, grey shadows and phone-photo smudges into pure white with sharp dark ink. Ideal for signatures, thumb impressions and declarations.
Lower = thicker, darker ink. Higher = lighter strokes, cleaner paper.

Official Photo & Signature Guidelines
Compare what your form demands with what this tool produces by default:
| Parameter | This tool (default preset) | Official requirement |
|---|---|---|
| Dimensions | 350 × 450 px | Exact pixel dimensions per notification — commonly 350 × 450 px |
| File size | Target 20 KB slider (adjustable) | Must stay inside the notification's KB window — most forms prefer 20–50 KB |
| Format | JPG / JPEG | JPG / JPEG only |
| Name & Date stamp | OFF — toggle anytime | Not required for this document type |
- Many government and exam forms cap images at 20 KB — always check the exact cap on your form.
- A 20 KB cap usually pairs with modest pixel dimensions (roughly 350 × 450 px or smaller in JPG).
- When a form specifies a range (e.g. 10–20 KB), aim for the upper-middle to maximize sharpness.
- Very dark or noisy photos compress poorly — good lighting gives smaller, sharper files.
- Keep the file in JPG/JPEG format — PNG files are typically 3–5× bigger at the same quality.
- Never compress below the minimum your form allows, or the image may look visibly blurred.
How to Resize in 3 Steps
Upload any photo
Upload a JPG/PNG/WEBP image of any size — processing happens entirely in your browser.
Set target to 20 KB
Slide the target-size control (or type 20 into the number box) to lock in your exact cap.
Download the compressed file
Hit download — the tool iterates JPEG quality until the file lands just under 20 KB with the best sharpness possible.
Frequently Asked Questions
How does the tool keep the file under exactly 20 KB?
It runs a binary-search over JPEG quality: each iteration renders the image at a slightly different quality level and checks the byte size until it lands just below 20 KB — delivering the highest-sharpness image that still fits.
My photo becomes blurry when it's compressed to 20 KB. Can I improve it?
Yes — the biggest win is starting from a well-lit photo with a plain background, because such images compress far more efficiently. Also make sure you're not over-enlarging the pixel dimensions; borderline oversized dimensions force heavier quality cuts.
Can I change the target size to something other than 20 KB?
Absolutely. The slider and number box let you target anything from 10 KB to 200 KB, and the custom-dimension fields let you set the exact pixel width/height your form demands.
Does compressing to 20 KB remove EXIF or GPS data?
Yes — the final file is re-encoded from the canvas, so EXIF metadata (GPS, camera model, timestamps) is stripped automatically. That's actually a privacy benefit for documents you share online.
Tip: if your form also requires a photo with name & date, use the SSC Photo Maker.
