More headroom than 20 KB
50 KB gives noticeably more room than 20 KB, so a slightly larger or higher-resolution signature scan can be preserved with virtually no visible compression.
Getting the best result
As with any signature, a clean scan on a plain background compresses best. Check whether your form also requires specific pixel dimensions.
Tips for the best result
- If your portal accepts either 20 KB or 50 KB, the 50 KB option will generally look slightly cleaner.
Frequently Asked Questions
