What 20 KB gives you

On 22 Oct 2026 we ran a 12-megapixel phone photo (3000 × 4000 px, 2.9 MB) through this page: it came out at 388 × 517 px, JPEG quality 53%, 19.9 KB. Your own photo will differ a little — a busy background takes more space than a plain wall.

The same photo at the other sizes: 50 KB → 767 × 1023 px · 100 KB → 1096 × 1462 px · 200 KB → 1842 × 2456 px.

Exam forms that ask for this size

Where a form also fixes the pixels, make the file on its exam page — it sets the size, KB and DPI together.

Kaise use karein

  1. Photo choose karein.
  2. 20 KB pehle se set hai — zarurat ho to badlein.
  3. Result dekh kar JPG download karein.

Privacy

Photo aapke device par hi rehti hai — kuch upload nahi hota.

Tip

At 20 KB a full phone photo shrinks to about 388 × 517 px (our test). Crop it to just the face or the signature first and the result stays sharper.

Questions people ask

How do I make a photo smaller than 20 KB?
Choose the photo. The tool first lowers JPEG quality; if the quality would drop below about 50%, it reduces the pixel size a little instead, so the photo stays clear. The result is always under 20 KB unless the photo cannot get that small.
Which forms ask for a file under 20 KB?
The SSC CGL, CHSL and JE 2026 signature (10–20 KB, about 6.0 × 2.0 cm) and the IBPS PO 2026 signature (10–20 KB, 140 × 60 px), from the official notices checked on 26 Sep 2026. The SSC and IBPS exam pages on this site make those files at the right pixel size too.
Is my photo uploaded?
No. Everything happens in your browser, and the page works offline once loaded.
Which KB does the tool use?
It keeps the file under 20×1000 bytes, which is slightly stricter than 20×1024. That way the file passes whichever way a portal counts a KB.
My form also needs exact pixel size (e.g. 200×230)
Resize the pixels first with the image resizer or the govt photo resizer, then bring the photo here if it is still too big.
