Common questions
What limitations apply?
Blur must be nonnegative; opacity is 0–100%. Offsets and spread may be negative. Output is a single outer CSS shadow.
Is my input saved?
No. It stays in browser memory and clears on refresh. Successful actions record only a stable tool ID and name, never your entered data.
