Gwtar Viewer vs HTML Viewer Simple

Gwtar Viewer opens Gwtar archives — self-extracting single-file HTML that packs a web page with all of its images and styles into one .html file. Gwtar files do not work when opened directly in a browser: they need a server that answers Range requests, fetching just the parts of the file that are actually needed. Gwtar Viewer runs a local server on your device to provide exactly that, letting the archive's own rendering logic do the rest. Your files are never modified. It also works as a viewer for ordinary HTML files, not just Gwtar. ■ Features - Open and read Gwtar files (.html) - Files you open are kept as history cards with thumbnails for quick reopening - Page zoom, remembered per file - Light / dark themes, English / Japanese UI - One-tap deletion of site data stored by archives ■ Privacy Everything happens on your device. The only network traffic is between the app and its own local server. Nothing is ever sent or collected externally. ■ Open source Gwtar Viewer is open-source software under the 0BSD license. See the support URL. The Gwtar format was designed by Gwern Branwen (this app is an independent implementation).

Open an HTML file and read it. That's all this app does — the simplest HTML viewer. Pick an HTML file from the Files app and it is displayed right away. No ads, no account, no tracking. Leaving out every unnecessary feature is the whole design philosophy of this app. Great for: - Reading HTML reports generated by AI tools such as ChatGPT or Claude - Carrying your own HTML files — travel itineraries, timetables, contact sheets - Checking HTML files received via email or cloud storage Open. Read. That's it.
