HTML Keep is a simple, lightweight tool for browsing local HTML / Markdown / ZIP files. When you receive or save an HTML / Markdown / ZIP file on your phone and the system tools cannot show it as directly as a computer can, HTML Keep helps you preview the file quickly. You can import HTML / Markdown / ZIP files into HTML Keep through Share or Open In, then view them on iPhone or iPad. -- Useful for -- · Opening HTML / Markdown / ZIP files sent by others · Previewing web pages and Markdown documents you made · Viewing local pages, notes, or web packages transferred from a computer · Temporarily browsing offline HTML content · Reading local Markdown notes, instructions, or documents · Viewing ZIP files that contain multiple web resources · Testing simple HTML and CSS pages -- Key features -- · Open HTML files locally · Native preview for Markdown files · Import and organize ZIP web packages · No account required · No login required · No cloud server dependency · Simple interface, ready when opened · Good for lightweight previews and everyday viewing -- Focused on one small problem -- HTML Keep is not a complex developer tool or a web hosting service. It focuses on one specific problem: helping you open local HTML, Markdown, and ZIP files more easily on your phone. -- Note -- Because HTML / ZIP files can structure and reference resources in different ways, some images, styles, scripts, or external resources may not display completely. Some Markdown extensions, embedded content, or external resources may also behave differently depending on where the file came from. This app is better suited for quick viewing, temporary previews, and everyday browsing of local HTML / Markdown / ZIP files. --- HTML Keep Pro: HTML Keep Pro is available as annual and monthly subscriptions.
