Choose New for a blank document or Open for an existing HTML file. Blue controls indicate the next available actions; Undo and Redo turn blue only when that history action is available. Select visible content to edit it, and use Add Element for supported document blocks.
Formatting
Select text before using the toolbar's Bold, Italic, Link, or alignment controls. To change an existing paragraph, heading, or list, select its block and use Block Style in the Selected Element panel. Add Element creates new blocks. Unavailable controls are disabled to protect the document structure.
Tables, Images, Video, and Process Steps
Select a table cell or process step for contextual structural controls. Images are embedded in HTML. Videos, captions, and posters remain files in the package's assets folder.
Undo and Redo
Use the toolbar or standard keyboard shortcuts. Save and Export do not clear recent document history.
Save, Save As, and Export
Save updates the active document.
Save As writes a new document and makes it active only after success.
Export HTML Copy creates an independent deliverable.
Export PDF Copy prepares an isolated print-ready copy and opens the browser print dialog without leaving the active document.
Portable Media Packages
Images are embedded in HTML, but videos and their associated caption and poster files are stored in the package's assets folder. Keep the HTML file and assets folder together when moving or sharing a document. A ZIP file is recommended for sharing.
Reopening documents with video: Your browser may require you to reconnect the media folder before videos will play. Choose either the folder containing the HTML file and assets folder, or the assets folder itself. This is a normal browser security requirement, not by itself a missing-video or document error. The browser may ask again in a later session.
Once reconnected, Last Mile restores access to the packaged videos. Save may separately request permission to write to the document folder. If Last Mile names a missing asset, confirm that the named file is still in assets and has not been renamed. If the file is present but cannot initialize, the recipient's browser may not support that video format. PDF copies use a poster image when one is attached; video does not play inside a PDF.
Exporting a PDF Copy
Last Mile opens a clean print view. An unavailable video can be printed as a poster or descriptive placeholder after a warning, but it still blocks portable HTML export. Last Mile cannot disable browser-controlled print headers and footers. In the browser print dialog, open More settings and disable the browser print headers and footers yourself. Enable Background graphics when document colors are important, review the preview, and save.
Troubleshooting
If media is disconnected, reconnect the original package folder or its assets folder before exporting. Select a folder, not the HTML file. Reconnecting restores read access; it does not copy, rename, or repair a genuinely missing asset. If a picker or print view does not open, allow file access or popups for this local application and try again. Draft recovery keeps one bounded Last Mile draft; if it reports that the draft is too large, save the document immediately.

What can Last Mile do?
Quite a bit, actually, but it depends on the file it is working with.
Here are a few examples:

Add additional basic elements
Create a new HTML file, such as a product report with supporting images or videos
Some complex HTML files may limit what Last Mile can do.
