Customizing the Editor

Atlas lets you tailor the writing environment to your preferences, separate from the publishing process. All editor customization is found in Settings > Editor Styles or can be accessed via the More menu in the iOS editor.

Info

Editor Style controls how your document looks while you're writing. Export Style controls how your document looks when it's rendered for HTML, ePub, or PDF. The two are independent — swap either one without affecting the other. See Custom Export Styles for the export-side equivalent.

Themes

Seven built-in themes are included: Nifty, Typist, Oolong, Birds of Paradise, Solarized, Natural, and Monochrome. A live preview grid shows how each theme looks, and can be toggled between light and dark color scheme previews.

Select any theme to apply it immediately. Themes include styling for all markdown elements, including objects like equations and annotations. You can also duplicate a built-in theme to create an editable copy, or create a fully custom theme with the Theme Editor. See The Theme Editor for a deep dive on custom themes.

Text Size Zoom

Adjust the base text size using the zoom stepper, scaling all text in the editor from 0.5x to 2.0x.

Line Height

The line height multiplier controls the spacing between lines of text. It ranges from 1.0 to 2.0 in steps of 0.25, with a default of 1.5.

Default Image Size

Set the default maximum display size for block-level images inserted into your documents. The range is 100px to 800px in steps of 50, with a default of 300px. Individual images can still be resized in the editor — see Images and Sketches for details.

Syncing Editor Settings

Editor preferences — your active theme, line height, and text size multiplier — can sync across devices via iCloud. Toggle this in Settings > iCloud.

Theme Importing and Exporting

Share and install custom themes using .atlastheme packages. Export your themes via the Share Sheet from Settings > Editor Styles, or import them through the file picker or by opening the file directly. Atlas registers .atlastheme as a supported document type on both platforms.

Atlas can also import Ulysses .ultheme files, automatically converting them to Atlas themes.

Tip

The Ulysses website has a collection of compatible themes at https://styles.ulysses.app/themes

See The Theme Editor for details on creating and customizing themes.
