HTML Editor
Read full descriptionHide full description
HTML Editor is a local-first iPhone and iPad app for opening standalone HTML files when another browser is not available from the share sheet. Open .html and .htm files from Files, AirDrop, WeChat handoffs, or other local document flows. The app renders the file cleanly in a built-in reader, then lets you switch into Edit mode for lightweight changes such as updating selected text or simple color styling. When you are done, export or share a new edited HTML file without requiring an account, server login, or cloud workspace. It is designed for saved pages, reports, notes, and document handoffs that should stay local on your device.
