How do I reduce a photo to exactly 20KB?

Upload your photo, type '20' in the target size field, and click Resize. The tool automatically finds the JPEG quality setting that produces a file at or under 20 KB.

Which exams require a 20KB signature?

SSC CGL, CHSL, MTS, CPO, JE and Stenographer all require signatures between 10–20 KB. IBPS PO, Clerk, SO and RRB exams also require signatures under 20 KB.

Will my signature still be readable at 20KB?

Yes, for a small signature image (140×60 px), 20 KB is sufficient for a clear, readable output. The tool maximises quality within the size constraint.

Can I also resize to 10KB or 30KB?

Yes. Enter any target value in KB — the tool adapts the quality setting to meet whatever target you set.
