How to Compress an Image to 30KB Online Free

Stuck between a 20KB minimum and a 50KB maximum? The 30KB sweet spot is real — especially for UTIITSL PAN signatures and bank exam uploads.

If your portal error says “file size exceeds 30 KB”, you need a dedicated compressor — not a generic “save for web” slider. OptiKit targets under 30KB while keeping signature strokes and facial features readable.

Who requires 30KB?

  • UTIITSL PAN signature — often stricter than NSDL photo limits
  • Banking recruitment forms — signature and thumb slots
  • Legacy state portals — mid-tier caps between 20KB and 50KB

Recommended workflow

  1. Scan signature on white paper at 300 DPI (or use a clear phone photo).
  2. Convert to JPG if the file is PNG or HEIC.
  3. Run through the 30KB compressor — resize happens before quality reduction.
  4. For exact PAN pixels, finish with the PAN card resizer.
