Free online WEBARCHIVE to HTM converter

A browser, editor, or publishing system may require ordinary HTML instead of Safari’s archived-page format. Converting the file produces an editable .htm document that is easier to share, inspect, version-control, or place on a web server.

What the WEBARCHIVE format is

WEBARCHIVE is Apple Safari’s saved web-page archive, normally stored as a binary or XML property-list file with the .webarchive extension. Safari creates it through File → Save As → Web Archive.

The archive contains a main HTML resource and may also contain CSS, JavaScript, images, fonts, and metadata. Safari users on macOS are the main source of these files; they are also found in older Apple-based archival and document workflows. A WEBARCHIVE is intended for offline viewing in Safari, not direct editing or normal web hosting.

What the HTM format is

HTM is an HTML document saved with the three-letter .htm extension. HTML contains the markup that browsers interpret, including headings, links, tables, forms, and references to stylesheets, scripts, and images.

.htm and .html represent the same HTML format. Browsers, source editors, static-site tools, and web servers generally open both extensions without Apple-specific software. The .htm extension is useful when an older system or application expects three-letter extensions.

How to convert WEBARCHIVE to HTM

Using 101convert.com is the simplest method when the file is not confidential:

1. Open the WEBARCHIVE-to-HTM converter on 101convert.com. It is available free without installing software.
2. Upload the .webarchive file and select HTM as the output format.
3. Start the conversion and download the resulting .htm file.
4. Open the result in a browser and a source editor. Check the text, character encoding, links, styles, images, and scripts.

Uploading a file to any online service may be unsuitable for confidential or regulated content. Use local extraction instead when the archive contains private information.

Extracting the main HTML resource locally

A WEBARCHIVE is a property-list container, so Python 3’s standard library can extract its main HTML resource on macOS, Linux, or Windows:

import plistlib
import sys
from pathlib import Path

source = Path(sys.argv[1])
target = Path(sys.argv[2])

with source.open('rb') as file:
    archive = plistlib.load(file)

main = archive['WebMainResource']
encoding = main.get('WebResourceTextEncodingName') or 'utf-8'
html = main['WebResourceData'].decode(encoding, errors='replace')
target.write_text(html, encoding='utf-8')

Save this as extract_webarchive.py and run:

python3 extract_webarchive.py page.webarchive page.htm

This writes the archive’s main document as UTF-8 HTML. It does not export or relink the CSS, images, fonts, or JavaScript listed in WebSubresources. A converter or extraction script that handles those resources is required for a self-contained offline copy.

Quality and compatibility limitations

Converting a WEBARCHIVE to one HTM file does not necessarily preserve the complete page. Images and stylesheets may remain referenced by their original web URLs, so the output can look incomplete when opened without an internet connection. If the archive stores resources separately, they must be exported and the HTML references must point to their local filenames.

Login-protected content, server-side features, advertisements, browser-specific scripts, and data loaded after Safari saved the page cannot reliably be recreated. JavaScript may also behave differently outside Safari.

Check the converted document in at least two browsers and inspect its source for a valid character declaration, preferably <meta charset="utf-8">. Preserve the original .webarchive file until the text, links, and required resources have been verified.
