Markdown Document Converter Cover Editor: Text, Shapes, and Logos

Add a cover without changing the Markdown body

The Markdown to PDF tool keeps cover design separate from the Markdown source. Turn on Cover, open the editor, choose a template, fill in the document details, and export.

The basic sequence is:

1. Load the Markdown body.
2. Turn on Cover in the toolbar.
3. Open the cover editor.
4. Choose a template that matches the document type.
5. Enter the title, date, organization, and other document details.
6. Adjust text, shapes, and images only after the information is final.
7. Close the editor and export a test PDF.

The cover is composed during PDF or HTML export. It may not appear in a preview that is focused on the Markdown body, so check both the editor canvas and the first page of the saved PDF.

The editor provides templates for minutes, proposals, reports, specifications, newsletters, contracts, portfolios, and other document types. The available set can change as the product evolves, so use the current list shown in the editor rather than relying on a fixed count. Start with Simple when you want a neutral layout. Choose according to what readers must identify first: recipient and publisher for a proposal, author and affiliation for research, or version and date for a specification.

Understand the editor

The left rail switches between templates, visual elements, and image upload. The top toolbar changes the selected object's properties. The central A4 canvas is where you select, move, resize, and directly edit objects.

A reliable workflow is to choose the template first, finalize the document information second, and add decorative elements last. This avoids rebuilding the layout when a title or organization name becomes longer.

Edit the canvas

Select an object and drag it to move it. You can add text, duplicate or delete objects, and adjust text color or opacity. The Elements panel adds rectangles, rounded rectangles, ellipses, lines, and thick bars. Hold Shift while resizing to preserve an object's aspect ratio.

Double-click text on the canvas to edit it in place. Press Enter or click outside to commit, and press Escape to cancel. For text objects, the toolbar controls font, point size, bold, italic, alignment, and color. Shapes support fill, border, border width, radius, and opacity. Lines support color and thickness.

Duplicate is useful when several labels need identical styling. Delete or Backspace removes selected objects. The editor also supports Ctrl/Cmd+C and V, Ctrl/Cmd+A, Ctrl/Cmd+Z, and redo with Ctrl+Y or Cmd+Shift+Z. These clipboard operations apply inside the cover editor.

Keep decoration subordinate to the title and publisher information. One accent color, consistent alignment, and generous whitespace usually produce a stronger business cover than many competing elements.

Add a logo or photo

Upload a PNG or JPG up to 3 MB. Choose Fit to show a full logo without cropping, or Fill when a photo should cover its frame. Check that small lettering remains legible at 100% PDF zoom and that the image contrasts with its background.

Selected images can be rounded, made partially transparent, or replaced while keeping their position. You can also double-click an image to replace it. Use Fit for logos and Fill for photographic backgrounds in most cases.

Color and practical composition

Start with a white or very light background, dark text, and one accent color. Shapes and lines can be bound to the cover accent so that one color change updates the related decoration. Do not rely on color alone to communicate meaning; headings and labels should remain clear in grayscale.

A business proposal cover usually needs only the document title, recipient, publisher, date, version, and a modest logo. A technical specification should prioritize system name, document name, version, update date, and responsible team. Keep summaries and detailed explanations in the body.

Example: business proposal

Start with Proposal, Corporate, or another restrained business layout. Replace the title first, then enter the recipient, submission date, version, and owner. Apply the organization's accent color and add a logo with Fit so it is not cropped. Keep the logo away from the title's reading area. If the cover feels crowded, remove decoration before reducing important text.

Example: technical specification

Prioritize the system name, document type, revision, update date, and responsible team. A neutral template with a strong title and a small metadata block is usually easier to maintain than a decorative layout. After adding a table of contents, confirm that export order is cover, TOC, then body.

Custom covers

The Custom template accepts Markdown or HTML and supports placeholders such as {{TITLE}} and {{DATE_JP}}. Use it when the built-in layouts cannot represent a fixed or specialized structure. Because long text and custom markup can affect pagination, always inspect the first page of the exported PDF.

Try a built-in template first. A custom cover is most useful for fixed legal wording, a specialized metadata arrangement, or a structure that must be repeated exactly. Keep custom markup small and avoid using the cover as a second introduction to the document.

Important behavior

The cover is combined with the document during PDF or HTML export and may not appear in the body-only preview. Review both the cover editor preview and the exported PDF. Switching away from a modified template may prompt you to reset that template's changes. Preview alignment controls can affect the preview only; move canvas objects when you need to change the exported composition.

Use “Reset to default layout” when you want to restore the selected template's original composition. Before using a broader tool reset, save your Markdown source because that action can affect the body and other settings. Turning Cover off exports the body without a cover; review the TOC setting at the same time.

If a title overflows, widen its box first, split secondary wording into a subtitle, and reduce the font only as a final step. If a logo is cropped, switch from Fill to Fit. If text disappears into a photo, increase contrast or place a translucent rectangle between the image and text.

When a template switch appears to discard edits, read the reset confirmation before continuing. Record important title and revision values before comparing several templates. “Reset to default layout” restores the selected template's composition; a broader application reset may also affect body content and other settings.

Preflight the exported cover

Check the saved PDF rather than relying only on the editor view:

• Title, date, organization, and revision are correct.
• The logo is sharp, uncropped, and has enough clear space.
• Text remains readable against images and in grayscale.
• The cover occupies exactly one page.
• The TOC or first body heading follows in the intended order.
• Paper size, orientation, background graphics, and browser headers are correct in the print dialog.

Open the result at 100% zoom. If recipients may print it, also inspect a grayscale preview. This catches low-contrast accents and thin logo lettering that can look acceptable on screen but fail on paper.

Before sharing, verify the title, date, organization, version, image quality, contrast, and that the cover occupies exactly one page.
