—About Signature to 20KB
Signature to 20KB optionally cleans a signature to crisp black or blue ink and compresses it to a target size such as 20KB. It is for forms that require a small signature file within a strict limit.
Signature uploads often face the same tight size caps as photos. Enhancing and compressing one locally meets the limit and keeps the signature private.
Step by step
- Drop a scan or photo of the signature to compress.
- Optionally enhance the ink to clean black or blue.
- Set the target file size, such as 20KB.

Tips for best results
