Compress Signature Between 10KB and 20KB
Many government exam portals specify signatures between 10KB and 20KB. A file below the minimum or above the maximum can fail validation. This tool targets the range, but you should still compare the final file with the active notification before submitting.

How it works
Crop tightly around the signature
Remove all blank paper margins. A tightly cropped image compresses much more predictably into the 10KB-20KB range.
Set target to 18KB
We target 18KB by default - safely above the 10KB minimum and comfortably below the 20KB maximum.
Verify and upload
Check the final file size and format, then compare the result with the active exam notification before uploading.
Frequently asked questions
Why 18KB and not exactly 20KB?
Some portals calculate file size slightly differently than your browser. Targeting 18KB gives you a safe buffer so you never accidentally exceed the 20KB limit.
What if my compressed signature is under 10KB?
If your signature is very simple (few strokes), it may naturally compress below 10KB. In this case, try using a slightly larger crop area or slightly higher quality setting to bring it above 10KB.
Which exams use the 10KB-20KB range?
Some recruitment notices specify a 10KB-20KB signature range, but the exact requirement depends on the active exam and cycle. Check the official notice before using this preset.
Why was my signature rejected as blurred or too small?
Start with a clear handwritten signature on plain paper, crop out excessive whitespace, and keep the complete mark visible. A blurred, miniature, incorrectly formatted, or poorly framed signature can be rejected. Check the current notification before uploading.
Paste an error or check an official upload phrase
Paste or type the exact message shown by the 10KB to 20KB signature upload application, or choose a verified notice phrase below. It is analyzed in your browser only; the message and files are not uploaded.
Common 10KB to 20KB signature upload problems
A correct file size alone does not guarantee acceptance. Check the final JPG/JPEG format, dimensions or physical size, clarity, whitespace, and the exact requirements for the exam portal you are using.
- File too large: reduce the output below the portal's maximum without making the strokes unreadable.
- Below the minimum: use a slightly larger crop or higher quality when the notice requires at least 10KB.
- Wrong format: export JPG/JPEG when PNG or another format is not accepted.
- Wrong dimensions: use a separate dimension preset when the notice specifies pixel width and height.
- Blurred or miniature signature: start from a clear original and keep the complete mark visible with limited whitespace.
