In short
Add to Calendar Link Generator is a free online tool on inputtesthub.com that generates one-click add-to-calendar links for Google, Outlook and Yahoo, plus the .ics file Apple Calendar needs. It needs no account, no download and no payment, and there is no daily usage limit. Everything is processed inside your own browser, so the data you paste is never uploaded to a server.
How to use the Add to Calendar Link Generator
- Fill in the event.
- Copy the HTML block, or take the links individually.
- Host the .ics somewhere and point the Apple link at it.
About the Add to Calendar Link Generator
The Add to Calendar Link Generator generates one-click add-to-calendar links for Google, Outlook and Yahoo, plus the .ics file Apple Calendar needs. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Adding a save-the-date button to a marketing email.
- Putting an add-to-calendar link on an event page.
- Sending a webinar link people can save in one tap.
Details
| calendar.google.com/calendar/render with a TEMPLATE action | |
| Outlook | Two links — one for outlook.com, one for Office 365 |
| Yahoo | A single query-string link |
| Apple | No URL scheme exists — a hosted .ics is the only way |
Times are converted to UTC from your browser's own time zone, so generate the links while set to the zone the event belongs to. An all-day event uses an end date one day later, because every one of these services follows the same exclusive-end rule as iCalendar.
Where this tool stops
One event per set of links, no recurrence and no attendees. Very long descriptions risk exceeding practical URL limits, which is around 2,000 characters in the strictest browsers.
Frequently asked questions
Why is there no Apple Calendar link?
Because Apple has never published one. Google, Outlook and Yahoo all accept an event as query parameters in a URL; Apple Calendar opens a downloaded <code>.ics</code> and nothing else. Every service offering a one-click Apple button is serving a file behind that link — which is exactly what the .ics here is for. Host it and link to it.
Which Outlook link should I use?
Both, labelled. <code>outlook.live.com</code> is for personal Microsoft accounts and <code>outlook.office.com</code> for work and school ones. They take identical parameters and differ only in the host, and a recipient signed into the wrong one gets a login page instead of an event.
Do the links work in an email?
Yes — they are ordinary links. Bear in mind that some email clients rewrite long URLs for tracking, and a very long description can push a Google link past what a browser will accept. Keep descriptions short and put the detail on a landing page.
Do I need an account to use the Add to Calendar Link Generator?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the utility.
Can you see what I put into this utility?
No. The Add to Calendar Link Generator runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
Who is the Add to Calendar Link Generator for?
In practice it gets used for three things: adding a save-the-date button to a marketing email. Putting an add-to-calendar link on an event page. Sending a webinar link people can save in one tap. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What are the limits of the Add to Calendar Link Generator?
One event per set of links, no recurrence and no attendees. Very long descriptions risk exceeding practical URL limits, which is around 2,000 characters in the strictest browsers. Knowing where a tool stops being trustworthy matters more than the cases where it works.
What are the reference figures here?
Google is calendar.google.com/calendar/render with a TEMPLATE action. Outlook is Two links — one for outlook.com, one for Office 365. Yahoo is A single query-string link. These are printed on the page itself, so you do not have to take them on trust.
Can I use the Add to Calendar Link Generator on mobile?
Yes. The page is responsive and the utility works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
