Free WhatsApp Link Generator

The format is deliberately simple: https://wa.me/447700900123?text=Hi%20there

• Digits only. No plus sign, spaces, dashes or brackets.
• Country code required, even for a local number.
• Message must be URL-encoded - a raw space or ampersand breaks the link.

Three formats open the same chat, and they are not equally good choices. https://wa.me/447700900123 is the short link WhatsApp's own click-to-chat documentation describes, and it is what this generator builds. https://api.whatsapp.com/send?phone=447700900123 is the older long form - it still resolves to the same conversation, but it is longer, uglier in a bio, and has one extra way to fail: forget the phone= key and nothing works. The third variant, the whatsapp://send URI scheme, only makes sense inside a native app that knows WhatsApp is installed; on a web page it dead-ends for anyone without the app.

A QR code is not a fourth format - it is a wa.me link wearing print clothes. Wrap the link this tool produces in any QR generator for packaging, table tents or a shop window, or use the code the WhatsApp Business app and WhatsApp Manager generate for your number. Either way the scan opens the identical chat, so everything below about pre-filled text and measurement applies to the printed version too.

The ?text= value must be percent-encoded, and the failures are specific rather than random. A raw space ends the readable part of the message; the correct escape is %20. A literal + is the classic trap: some encoders emit it for spaces because that is the old form-submission convention, but a plus sign in a wa.me query can surface as an actual "+" character in the message box instead of a space - if you see "Hi+there" in WhatsApp, this is why. An unescaped & silently cuts the message at that point, because the browser reads everything after it as a new query parameter, and a # ends the URL entirely.

Emoji are legal but expensive: each one percent-encodes to four or more UTF-8 escape sequences, so %F0%9F%91%8B is a single waving hand. The message still works - this generator uses encodeURIComponent, which handles spaces, symbols and emoji correctly - but a QR code built from an emoji-heavy link gets visibly denser and harder to scan. Keep the pre-fill to one short, editable sentence; the recipient has to press send themselves either way.

Most wa.me links live in bios, email signatures and Google Business Profiles, where the only cost is your reply time. The interesting placement is paid: Click-to-WhatsApp ads on Facebook and Instagram use the same click-to-chat mechanics as their call-to-action, and Meta's pricing gives a conversation opened from one of those ads a free entry point - for 72 hours, messages in that thread are not billed, templates included. If you sell through the WhatsApp Business API, that makes an ad-opened conversation cheaper to run than one you re-open later with a paid template. The messaging windows and tier caps that govern all of this are collected on the WhatsApp limits reference, and the API cost calculator will put a monthly number on your template volumes.

The instinct is to append utm_source=... to the wa.me URL. It does nothing: WhatsApp reads only the number and the text= value, and the conversation that opens never lands on a page your analytics can watch. Measurement has to happen one step earlier. Tag the landing page or ad that hosts the WhatsApp button with UTM parameters - the UTM campaign builder covers the naming rules - then record the tap itself as an outbound-click event in your analytics tool. For the conversation side, a short code word in the pre-filled message ("Hi, I'm asking about the spring offer") arrives as the opening line, so a human or a keyword rule can attribute the chat even though no query string survived the jump.

1. Leaving the plus sign in. wa.me/+44... fails. The generator above strips it for you.
2. Dropping the country code. A number that works when dialled locally will not work in a wa.me link without it.
3. Pasting an un-encoded message. Everything after the first space is silently discarded.

A click-to-chat link routes people into a personal inbox. That is fine at low volume. It stops working when messages arrive faster than someone can answer them, when they come in overnight, or when several people need to handle the same number - there is no queue, no assignment and no history beyond one phone.

At that point the number needs to be connected to a WhatsApp chatbot so common questions are answered automatically and the rest reach a shared inbox. Automated replies outside the 24-hour service window also require approved message templates, which is worth knowing before you build a campaign around outbound.
