If you need to save a web page as one self-contained HTML file, Save Page WE is the closest alternative to SingleFile: its listing describes saving the displayed page into a single HTML file and supports one-page, multi-page, URL-list, and command-line workflows. If your goal is to organize a long-term web archive, WebScrapBook may fit better; if you only need a basic copy, Firefox’s built-in save options may be enough—but “Web page, complete” creates a separate assets folder, while “HTML only” is not a self-contained capture.
Choose by what “one file” means
A saved page can mean either one HTML document with its resources embedded, or an HTML document accompanied by a folder of images and other assets. Those are different outputs. If you require a single portable HTML file, choose a tool that explicitly embeds resources or saves a single-file capture. If a folder beside the HTML file is acceptable, Firefox’s complete-page save is a built-in option.

SingleFile may already do what you need
Before switching, check whether SingleFile’s existing workflows cover the task. Its Chrome listing describes saving a complete page with CSS, images, fonts, and frames into one HTML file. It also lists selecting content, frames, and links; adding annotations; processing multiple tabs; autosaving; and sending captures to supported cloud destinations. See the SingleFile Chrome listing.

Best close replacement: Save Page WE
Save Page WE is the most direct alternative when the requirement is a single HTML file. Its Firefox listing says it saves a page as currently displayed into one HTML file that can be opened in any browser. The same listing says Firefox and Chrome versions have identical functions and interfaces, and describes saving one page, selected pages, or a URL list, as well as command-line automation. These are publisher-described features, not independently measured results. Save Page WE on Firefox Add-ons.

The listing summarizes its purpose this way: “Save a complete web page (as currently displayed) as a single HTML file that can be opened in any browser.” Its “highly accurate representation” wording is product copy, not a verified comparison against SingleFile or other tools.

- You want a straightforward single-HTML output rather than an archive collection.
- You need to save more than one page, work from a URL list, or automate captures from the command line.
- You prefer a browser extension and want the listing-described Firefox or Chrome option.
Best for an organized web archive: WebScrapBook
WebScrapBook can save a capture as a single HTML file, but it is broader than a one-click replacement. Its extension listing describes customizable capture, page selection, source-page capture, and bookmark saving. It also supports folder output and ZIP-based HTZ or MAFF archives, alongside retrieval, organization, annotation, and editing workflows. WebScrapBook on Firefox Add-ons.

When it fits
- You want to manage and revisit a collection of captures, not just produce one file.
- You may want to choose between a single HTML document, a folder, or an archive format.
- Annotation, editing, or organizing captures matters as much as the output format.
Firefox’s built-in save: useful, but know the output
Firefox offers two relevant save choices. Mozilla distinguishes “Web page, complete,” which saves the HTML plus a directory for pictures and other files needed to display the page, from “HTML only,” which saves the original page structure and links in one file. Neither should be treated as equivalent to a self-contained single-HTML capture: the complete option uses a separate assets directory, and HTML only does not embed those assets. Mozilla’s guide to saving web pages.
Use the built-in option when you need a basic local copy and can accept its structure. Choose an extension that explicitly creates one self-contained HTML file when portability as a single file is essential.

ScreenshotNeo is for screenshot output, not an HTML archive
If what you need is a visual record rather than an editable, self-contained HTML file, ScreenshotNeo is a website screenshot API and MCP server for developers. It returns PNG, JPEG, WebP, or PDF from a URL; it does not replace SingleFile-style HTML archiving. Its clean-shot workflow accepts consent banners and removes supported consent platforms, newsletter popups, and chat widgets before capture. Bot checks, blank pages, timeouts, failed loads, and cache hits are not billed, with response headers indicating the page verdict and billing status. Its MCP server offers tools for AI agents, including Claude, Cursor, and other MCP clients.
