How to Open a .webarchive File on Windows
A .webarchive is a whole web page — HTML, images, stylesheets — saved into a single file by Safari. Only Safari opens it directly, which is a problem the moment the file reaches Windows or Android.
.webarchive
Why it will not open
- It is an Apple format. The file is a binary property list containing the page and every resource it referenced, and nothing outside Apple's ecosystem reads that structure.
- Renaming it to .html does not help. The HTML is one entry inside a binary container, not the file itself.
- It is easy to produce by accident — in Safari, Save As defaults to Web Archive, so people send them without realising the recipient may not be able to open them.
How to open it
Ask for a PDF instead
- 1 In Safari: File > Export as PDF, or Save As and choose Page Source for the raw HTML.
- 2 PDF preserves the layout exactly and opens anywhere. For a page that was saved as a record, this is usually what was wanted in the first place.
On a Mac
- 1 Open it in Safari, then File > Export as PDF to convert it into something portable.
- 2 From Terminal, textutil -convert html file.webarchive produces an HTML version, though external images may not survive.
On Windows
- 1 There is no native application. Some archive utilities can list the contents because a binary plist is parseable, but the result is fragments rather than a readable page.
- 2 Realistically, converting on a Mac or asking for a PDF is the practical answer.
It is a binary property list
The same container Apple uses for .plist. The identifier on this site reports it as such, which is why the two formats can look alike at the signature level — both begin with bplist00.
