When your form allows 20 KB signatures
Some forms allow signatures up to 20 KB instead of the stricter 10 KB. The extra room gives a slightly cleaner signature. Use the largest size your form accepts.
As with all signatures, sign in black ink on plain white paper for the best result — the background is what usually blocks compression.
Frequently asked questions
Is my signature uploaded or stored?+
Never. It's processed entirely in your browser.
10 KB or 20 KB?+
Use the larger size your form allows. 20 KB gives a slightly sharper signature than 10 KB.
Why won't my signature compress?+
Usually a coloured or textured background. Re-scan on plain white paper in even light.
