Tap the file in Files, Gmail, Drive or your chat app and choose HTML Viewer & Editor under Open with. You can also open the app and pick a file, paste code, or start a new file from a template.

A page can only load the files you allow. Tap Allow folder in the preview and choose the folder that holds the HTML file. You do this once, and the images, stylesheets and scripts next to the file then load.

Yes, Save writes to the file you opened. Use Save as to keep the original and write a copy somewhere else. The app never writes an empty text over a file that has content.

The app keeps earlier versions of a file when you save. Pro shows them in version history so you can look at one and restore it. If the app closed before you saved, the text you had not saved comes back when you open the file again.

It is a Pro feature that you start yourself. It serves only the page you opened, only to devices on your local network, such as a phone or tablet on the same Wi-Fi, under a random token in the address. It stops when you stop it and by itself after 30 minutes without requests. Nothing is sent to our servers.

Installs made before 13 November 2026 may get Pro unlocked at no cost. This offer can change. If it applies to you, Settings shows Early supporter: Pro is unlocked for you, and you keep Pro afterwards.

Purchases are processed by Google Play, so refunds follow Google Play’s refund policy. You can request one from your Google Play order history. If Pro does not work for you, email us as well and we will help.

Your files stay where you saved them. Drafts and earlier versions are in the app’s private storage, and uninstalling the app deletes them. We hold no account of yours. Anonymous usage statistics and crash reports sent to Google Firebase are deleted automatically after 2 months, and you can switch them off in Settings > Privacy.
