SSC requires your signature as a JPEG between 10KB and 20KB, approximately 4.0×2.0 cm. Sign on white paper with black ink and scan clearly.

Does this tool support left thumb impressions?

Yes. Left thumb impressions follow the same size guidelines (usually under 20KB) and clean background requirements as signatures. You can crop, clean, and compress them here.
