Compressing a Signature to BPSC Under 15KB
How it fits: Crop margins are removed, background thresholded to pure white, and file compressed to 13.4KB, under the 15KB cap.
Why is the portal rejecting my upload?
Most application rejections are caused by hidden dimension or background mismatches rather than KB limits alone.
BPSC portal error: 'File size must be less than 25KB'
Cause: Uploading 50KB or 100KB photo commonly produced by standard compressors.
Fix: Use ToolKB's BPSC Photo preset which calibrates output to 22KB.
Signature upload rejected as exceeding 15KB
Cause: BPSC has an extremely tight 15KB ceiling for signatures.
Fix: Use ToolKB's BPSC Signature preset which limits file weight to 12KB to 14KB.
Missing Hindi signature error
Cause: BPSC requires two separate signature files: one in English and one in Hindi.
Fix: Sign your name in English and separately in Hindi script, scanning both as individual files.
Square 1:1 aspect ratio mismatch
Cause: Uploading rectangular 3.5 × 4.5 cm passport photo to a 250×250 square box.
Fix: ToolKB's BPSC preset automatically center-crops to a balanced 1:1 square.
Blurry text on 14KB signature
Cause: Excessive compression on grey camera background.
Fix: Enable Ink Boost above to whiten background paper and sharpen ink lines.
Server error 413 on onlinebpsc.bihar.gov.in
Cause: Uploading large uncompressed camera files.
Fix: ToolKB compresses files in your browser before upload, avoiding server timeout.
