Create Date Stamp
About the Date Stamp Tool
This page lets you quickly create a date stamp for your documents. When moving from paper forms to online templates, it produces today's date with a single click, making it handy for internal confirmations and receipts that need a simple acknowledgment.
It is useful for recording internal inspections or equipment handovers where a formal date entry is required. Your chosen style is saved automatically, so you can reproduce the same format whenever you revisit the tool.
Because most processing occurs in your browser, the entered data is not sent outside your device. Templates and fonts are automatically arranged to produce uniform impressions. Only when using the signing feature is the necessary information transmitted to external servers.
Generated seals include a tamper-detection feature but do not guarantee legal validity. For important contracts or governmental procedures, follow organizational rules and use formal electronic signatures when necessary. Handle generated stamps carefully to prevent unauthorized use.
