BPSC Photo and Signature Size: Bihar Portal Working Caps (Free Tool)
Bihar civil services and state exams route through a portal with tight imaging caps: the photo commonly sits at or under 50 KB, the signature at or under 30 KB, both JPEG with plain backgrounds.
The caps are low enough that phone originals never fit, and high enough that over-compression ruins verification clarity. The window is narrow; this is how to sit inside it.
Working caps to target
Photo: JPEG near 4.5 x 3.5 cm at or under 50 KB. Signature: dark ink on white at or under 30 KB. Recent BPSC cycles have held close to these numbers.
- Your cycle s notice states the exact caps; treat these as preparation targets, not promises.
Aim a few KB under each cap so portal re-encoding cannot push you over.
Measure before you compress
The compressor reports achieved size per pass, so you know exactly where you land instead of guessing from quality sliders.
- Add the cropped photo and run the target preset at 50 KB.
- Check the readout; sit a few KB under the cap.
- Repeat for the signature at 30 KB, then download both.
Clarity at low caps
At 50 KB the face has real budget; at 30 KB the signature does not. Keep strokes thick and the crop tight so compression spends on ink, not margins.
Grey paper backgrounds eat the budget first; lift to white before compressing.
Verification-day checks
BPSC verifies originals against uploads at document check; heavy filters or beautification raise queries. Keep the photo honest: neutral expression, even light, no edits beyond crop and compression.
