Mailto Link Generator

A plain email address on a page forces the visitor to copy it, open their mail program, and type a subject from scratch. A mailto link removes that friction: one click opens a new message with the address, subject, and body already filled in, so the visitor only has to press send.

This generator builds the link with proper encoding, so subjects and messages containing spaces, punctuation, or line breaks survive intact. Use the result in a contact button, a support page, or an email signature.

Quick Answer: Build a mailto link with a prefilled subject and message body.

Best Practices and Tips

Double-check your input before running the tool, since the output is only as good as what you enter.
Keep a copy of the original input until you have confirmed the result works.
Keep the subject specific so replies are easy to sort.
Prefill the body with a short template, not a whole letter.
Test the link in your own mail program before publishing.

Common Mistakes to Avoid

Running the tool on incomplete input and trusting the first result without a glance.
Forgetting to save or copy the output before closing the tab.
Leaving the subject blank, which makes replies harder to organise.
Forgetting that mailto links need a mail program on the visitor device.

Frequently Asked Questions

What does the Mailto Link Generator do?

The Mailto Link Generator takes an email address, a subject, and a body and turns it into a mailto link that opens a prefilled email, right in your browser. You do not need to install anything or create an account, and the result is ready in seconds. It is built for everyday jobs where you want a quick, reliable answer without opening a heavy desktop program or uploading your files anywhere.

Is my input private when I use this tool?

Yes. Everything you type, paste, or upload is processed locally in your own browser tab, so it never travels to a server run by this site. The only exception is a feature that explicitly needs a device, such as a camera or microphone, and even then the media stays on your device. Closing the tab ends the session, and nothing about your input is stored on the site.

What should I do if the result looks wrong?

First, check the input for typos, missing values, or an unsupported format, because most unexpected results come from the input rather than the tool. Try a small, simple example you can verify by hand, then compare it with the tool output. If the simple case works and the real case does not, the difference usually points to the part of the input that needs fixing.

Does the link send the email by itself?

No. It only opens a new message with the fields filled in. The visitor reviews the message and presses send, so nothing is ever sent without their confirmation.

Why does the link look full of percent signs?

Spaces and special characters are percent-encoded so the link stays valid. The mail program decodes them back when it opens the message, so the recipient sees normal text.

Can I use this tool on a mobile phone?

Yes. The tool is built with the same responsive layout as the rest of the site, so controls, inputs, and results adapt to a phone screen. Buttons are large enough to tap comfortably, text fields accept mobile keyboards, and results wrap instead of overflowing. If a feature needs a device capability, such as a camera, the tool will say so on that device rather than failing silently.
