SSC-style KB window

Compress a JPEG Between 20 KB and 50 KB (Window, Not Just a Cap)

Most compressors only cap the top | but SSC-style forms reject files that are too small as well. A window needs both edges enforced.

Open SSC Photo Resizer
The SSC tool enforces both edges of the window: 413 × 531 px, 300 DPI stamped, 20-50 KB verified.

Why would a file be too small? Over-compressing a tiny crop can drop under 20 KB, and some portals read that as a low-quality or placeholder image. The fix is honest sizing: crop to the real spec (413 × 531 px for 35 × 45 mm), let the quality ladder come down only as far as the window allows, and verify the achieved size before upload.

SSC Photo Resizer was built for exactly this band | it stamps true 300 DPI metadata, keeps the file between 20 and 50 KB, and prints the achieved size on the result card. For a pure cap without the form spec, the Image Compressor opens with any target pre-filled.

Everything runs on-device: ID photos and signatures never touch a server, and there is no daily limit or watermark.

What if my file is already under 20 KB?
Re-export from a larger original or raise the quality | compressing further only makes it worse. The SSC tool warns honestly when the window cannot be met from the given crop.
Is 20-50 KB the universal exam window?
No | SSC uses 20-50 KB for photos and 10-20 KB for signatures, UPSC allows 20-200 KB. Always follow your notification | both tools accept custom windows.
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.

How to land inside 20-50 KB

  1. Open SSC Photo Resizer | the 413 × 531 spec and 20-50 KB window are pre-set.
  2. Add your photo and centre the face with focus sliders.
  3. Run | the result card verifies pixels, DPI stamp and achieved KB.
  4. Download and upload with confidence.
