Compress a JPEG to 30 KB Online Free

30 KB is a favourite of UPSC-style forms and many state portals for photos and signatures alike. | UPSC-style photo band.

Compress to 30 KB now
The tool opens with the 30 KB target already applied | nothing is uploaded anywhere.

Start from a tight crop at around 413 × 531 px (35 × 45 mm) and the ladder lands inside 30 KB while the face stays sharp. If the portal also prints a minimum (say 20 KB), the result card shows the exact achieved size so you can verify both ends of the window.

Typical askers: UPSC photo/signature slots, police verification packets, court filing portals.

Portals reject files by the byte, so guessing with quality sliders wastes hours. This preset runs a measured quality ladder (and downscales only if quality alone cannot reach the target) on your own device, then reports the achieved size before you download. Your file never leaves the browser tab.

Will the image still look acceptable at 30 KB?
It depends on the picture: tight crops and flat subjects compress beautifully, while wide busy photographs give up fine detail. The live preview lets you judge before downloading.
Is my photo uploaded anywhere?
No. Every pixel is processed by JavaScript inside your own browser tab | nothing is sent to a server, stored or logged, which matters when the file is an ID photo or signature.
Does this work on my phone?
Yes. The tool is fully responsive and touch friendly, and the whole conversion runs in the mobile browser itself | no app install.
