In short
WhatsApp Link Generator is a free online tool on inputtesthub.com that builds a wa.me click-to-chat link with a pre-filled message, cleaning the number to the international form WhatsApp requires. 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 WhatsApp Link Generator
- Enter the number with its country code.
- Add a message if you want one waiting in the box.
- Copy the link, or take the HTML for a button.
About the WhatsApp Link Generator
The WhatsApp Link Generator builds a wa.me click-to-chat link with a pre-filled message, cleaning the number to the international form WhatsApp requires. 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
- Putting a "Chat on WhatsApp" button on a website.
- Adding a click-to-chat link to an Instagram bio.
- Sending a link that opens a chat with a message already typed.
Details
| Format | https://wa.me/<number>?text=<message> |
|---|---|
| Number | Digits only — no +, no spaces, no leading zero |
| Saving the contact | Not needed by either side |
| The message | Typed into the box, not sent — the person still presses send |
Two link forms exist and both work:
wa.me is the short one WhatsApp promotes, and api.whatsapp.com/send is the older one that behaves identically. Both are given above. The whatsapp:// scheme is for native apps only — on a web page it fails silently for anyone without WhatsApp installed.Where this tool stops
Cannot send a message, add a contact, or open a specific group. Very long pre-filled messages are truncated by some WhatsApp versions at around 2,000 characters.
Frequently asked questions
Why does my link say the number is invalid?
Almost always the national trunk zero. A UK number written 07700 900123 at home becomes 447700900123 internationally — the 0 is dropped, not kept after the 44. Leaving it in gives 4407700900123, which WhatsApp opens and then rejects, and it reads like a WhatsApp fault instead of a typo. This tool strips the +, spaces and punctuation, and warns when a trunk zero is still there.
Does the recipient have to save my number?
No, and that is the whole point of click-to-chat. Either side can open a conversation from the link without adding the other to their contacts, which is why businesses use it rather than publishing a number.
Is the pre-filled message sent automatically?
No. It appears typed into the message box and the person chooses to send it or change it. There is no way to make WhatsApp send on someone's behalf, and any service claiming otherwise is not doing what it says.
Does the WhatsApp Link Generator cost anything?
There is no cost and no cap. The WhatsApp Link Generator is not a demo of a paid product, so nothing is held back or watermarked.
Is what I paste into the WhatsApp Link Generator stored?
No. The WhatsApp 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.
What problem does the WhatsApp Link Generator solve?
Typical uses: putting a "Chat on WhatsApp" button on a website. Adding a click-to-chat link to an Instagram bio. Sending a link that opens a chat with a message already typed. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
When is the WhatsApp Link Generator not the right tool?
Cannot send a message, add a contact, or open a specific group. Very long pre-filled messages are truncated by some WhatsApp versions at around 2,000 characters. Knowing where a tool stops being trustworthy matters more than the cases where it works.
Which values should I know?
Format is <code>https://wa.me/<number>?text=<message></code>. Number is Digits only — no +, no spaces, no leading zero. Saving the contact is Not needed by either side. These are printed on the page itself, so you do not have to take them on trust.
Does the WhatsApp Link Generator work on a phone?
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.
