Why we built it.
Create polished business letters with millimeter-accurate DIN 5008 geometry, window envelope alignment, vector signatures, and private 300 DPI PDF export. 100% in-browser with zero cloud uploads.
The problem
Word processors drift layout margins and address blocks when editing text, while design tools flatten vector text and store private executive correspondence on external cloud servers.
The solution
A focused letter editor with locked DIN 5008 Type A/B window envelope geometry (45 × 85 mm), multi-page continuation headers, vector pen signatures, rubber notary seals, and 100% in-browser privacy.
The workflow
Select institutional typography. Enter recipient details. Draw vector signature. Export print-ready 300 DPI vector PDF in under 30 seconds.
The outcome
Free to use, no sign-up, and every document stays on your own device.
