The tool lets you edit an HTML email body and download a table‑based, inline‑styled .html file ready to paste into any email client. It preserves the visual layout by converting the content into editable blocks and saves the result as UTF‑8 HTML without any page metadata or scripting. Works for standard email bodies; advanced scripts or external style sheets are outside the tool’s scope.

Editable block conversion

When an HTML email file is opened, the editor parses visible elements and creates draggable blocks such as plain text, headings (three levels), lists, links, quotes, and image placeholders. This lets the visitor edit, rearrange, or delete pieces without touching raw markup while the tool rebuilds the body with email‑compatible tables and inline CSS.

During conversion, the document head, external style sheets, script tags, and any markup that does not map to a supported block are omitted. Unsupported markup is simplified to plain text, so the saved file contains only the content needed for reliable email display.

Image handling

Image blocks accept only absolute HTTPS URLs. When an image is added, the link is stored directly and no binary data is embedded, keeping the output lightweight and ensuring reliable loading in email clients.

When a file is opened, any image reference that is not an absolute HTTPS URL—such as relative paths, data‑URI embeds, content‑ID references, or plain HTTP links—is removed. The same filter runs on save, and the editor reports the number of removed image blocks.

Saving and output

After editing, the "Save as HTML" action generates a UTF‑8 file that contains only the email body, formatted with table‑based layout and inline styles. The original filename is retained (changing .htm to .html if needed) and the download starts immediately while the editor stays open.

The downloaded file is intended for pasting into any email client or sending service. It contains no page metadata, scripts, or external resources beyond allowed HTTPS image links, and the download link remains active for 24 hours.

Limits and scope

Single file editing: Handles one .html or .htm file per session, covering typical email‑body editing needs.
Retention window: Opened files and generated downloads remain available for 24 hours before automatic removal.

FAQ

What does the editor do with images that are not absolute HTTPS links?

It removes them during opening and again on save, and reports how many image blocks were removed.

Are scripts or styles from the original HTML retained after editing?

No. The head, external style sheets, scripts, noscript sections and unsupported markup are omitted; only inline‑styled email‑compatible body remains.

Can I add an image by dragging a file into the editor?

No. Images must be added as blocks with an absolute https:// link; file drops or pastes are rejected and a notice prompts you to upload elsewhere.

What is the maximum file size I can upload to the HTML Email Editor?

The upload limit varies by account tier: anonymous users can open smaller files, a free Aspose account raises the limit, and Premium or Business accounts allow larger files; the opened HTML file size is what counts toward the limit.

How long are my uploaded files and generated downloads kept on the server?

Both opened files and the generated download links are retained for 24 hours before they are automatically deleted.
