chrome://extensions(in Edge:edge://extensions) and switch on Developer mode. - Click Load unpacked and choose the unzipped folder.

Firefox removes add-ons it hasn't signed when it restarts, so you load it again after a restart until it's on Firefox Add-ons. In Firefox Developer Edition or Nightly it can stay: set xpinstall.signatures.required to false in about:config, then choose Install Add-on From File in about:addons.
Install it in Safari (Mac)

xcrun safari-web-extension-converter --macos-only, drag the unzipped folder into the window, and press Return. Xcode opens the new project. - Press Run (▶) in Xcode, which builds and opens the small app once.

- In Settings > Extensions, turn on Share Large Files Free and allow it on mail.google.com and Outlook.
Safari turns Allow Unsigned Extensions off again when it quits, until the extension is on the Mac App Store. On iPhone and iPad, use the website or add it to your Home Screen instead.

Work or school account? If Add a custom add-in is missing, your IT team can add the same address for everyone in the Microsoft 365 admin center.
Gmail
Install the browser extension: every email you write in Gmail gets a Large files button next to Send. It opens the side panel, and the link goes into your email when the upload is done. Nothing is attached, so Gmail's 25 MB limit doesn't apply.
On a phone, use the app: share files to it from your gallery, then paste the link into Gmail.
App for your phone and computer

- iPhone and iPad (Safari): tap Share, then Add to Home Screen.
- Windows, Mac, ChromeOS (Chrome or Edge): click the install icon at the right of the address bar, or menu > Install.
More detail in the guide: install the app and share from your gallery.

Frequently asked questions
Is the browser extension free?
Yes. It sends through this website, with the same free limits, and needs no account.
Which browsers does the extension work in?
Chrome, Microsoft Edge, Brave, Opera and other browsers built on Chromium, Firefox 140 or newer on a computer and Safari on a Mac. In Firefox it opens in the sidebar; in Safari it opens in a tab, and the Gmail and Outlook button opens a window on the page.
Why does Firefox remove the extension when I restart it?
Firefox only keeps extensions that Mozilla has signed. Until it's on Firefox Add-ons, the version you load yourself stays until you close Firefox. Firefox Developer Edition and Nightly can keep it: set xpinstall.signatures.required to false in about:config and install the zip from about:addons.
Does the Gmail button attach the files to the email?
No, and that's the point: the files are uploaded here and the email gets a download link, so Gmail's 25 MB attachment limit doesn't apply.
Does the Outlook add-in work in new Outlook and on the web?
Yes. It works in new Outlook for Windows, classic Outlook on Windows and Mac, and Outlook on the web, for any account where you can add your own add-ins.
Can my company install the Outlook add-in for everyone?
Yes. An administrator can deploy the same manifest address for all users from the Microsoft 365 admin center (Integrated apps).
What data does the extension read?
Only what it needs: on Gmail and Outlook it adds a button to the email you are writing and puts the link where your cursor is. It doesn't read or send your emails anywhere.
