Fit signatures into a 10KB to 20KB range
Some exam and application forms reject signatures that are too small as well as too large. This page targets a file-size window, helping the signature stay above the minimum while still staying under the maximum.
10KB to 20KB signature checklist
- Confirm both the minimum and maximum KB values before processing.
- Avoid overly complex backgrounds because they can push the file above 20KB.
- Check that the signature remains readable after the file-size adjustment.
- Use the downloaded signature only if it falls inside the full KB range.
