Crater Editor

A professional, accessible, and interactive take on digital content creation

Introducing the Crater Editor

You need power. You need accessibility. You need the Crater Editor - Joomag's incredibly versatile online editor. Select from 3 unique starting options to fire up your creativity. Then innovative on each page as every publication you create is brought to life like never before.

Get Ahead by Getting Started

Your blank canvas awaits.

Choose from over 300 professionally designed templates and replace their content with your own.

Then supercharge its preexisting content with extra interactivity.

Publication Types

Single Spread

Create a publication in single page format. Adjust page sizes by selecting their width and height. Ideal for creating e-books, presentations, and newsletters.

Double Spread

Double the fun with a double spread format. Practical for creating magazines and catalogs.

Long Pages

Create longer, scrollable content by adjusting the height of a page. A great choice for newspapers and brochures.

The Perfect Layout

A well-organized layout can make or break your content's readability. People need access to information quickly, and a clean-cut design can make that information visually appealing and easy to find. Use the Crater Editor to easily arrange specific elements within a page, ensuring more consistency with a compelling layout.


Baseline grids resemble ruled notebook paper, helping align columns of text. Document grids resemble graph paper and are primarily used for aligning objects. Utilize both in addition to comprehensive line spacing and horizontal/vertical grid spacing features.

Snap Tool

Easily position objects in alignment with grid lines and other reference points on a page. With snapping enabled, objects can automatically jump to an exact position when dragged near the desired location.


Page guides appear only on the pages they are created on. Spread guides span every page, including the Drawboards of a multi-spread page. Both types can be placed horizontally or vertically on any page.


A margin is the extra space between the edge of a page and its main content. The top, bottom, left, and right margins form a rectangle around a page's perimeter, helping define where a line of text begins and ends. Use them all to better adjust content in a specific area.

Adding Photos and Slideshows to a Publication

Showcase dazzling photos like never before. Upload images directly to a publication and edit each one via Joomag's photo editor tool. Or combine them all into a single, fully customizable slideshow.

Adding Photos

Incorporate photos into publications with the Crater Editor's Photo tool. Then crop, rotate, or transform them to your heart's content.

Editing Photos

Joomag's industry-unique Photo Editor can dramatically alter the appearance of any photo. Add special effects, apply different filters, place text on images, attach stickers, and much more.

Creating Slideshows

Save space and engage readers at the same time by combining multiple images into a single, interactive slideshow.

Video and Audio

Put the "extra" into "ordinary content" with the Crater Editor. Imbue publications with rich audio and video elements to captivate readers while boosting engagement.

Embedding Video

Need to draw attention towards a specific aspect of the page? Upload videos from a PC or from popular video sharing websites such as YouTube and Vimeo. Feel free to change a video thumbnail by uploading your very own, too.

Placing Audio

Add SoundCloud audio files to a publication or upload personal files from a PC. Set music to play for the duration of a publication, or for specific pages only. Either way, readers will enjoy the melodic experience.

Working with Text

A picture may be worth a thousand words, but those words are likely different for each of us. Great text can lend to the overall cohesiveness of a page's layout, so getting it right is important. With the Crater Editor's Text tool, add text to a publication, change line and letter spacings, or apply kerning.

Fun with Fonts

Fonts can increase legibility, represent entire brands, emphasize an idea, and add personality. Picking the right one with Joomag is easy, whose platform can also upload custom fonts in both TTF and OTF formats.

Creating Multi-Column Text

Multi-column texts are common in the publishing industry. Create an infinite amount of columns (if you wish) and use Joomag's Gutter tool to adjust the spaces between them.

Adding Interactive Elements

Static content won't cut it anymore. Readers expect some sort of interactivity from digital content. The text-only reading experience is no more; the dawn of interactive publishing is here.

Hotspot Tool

Add hotspots to your content, link them to any external websites, or direct readers to different pages within the publication. It's an invaluable tool for providing instant access to content and enhancing the overall reading experience.

Facebook Share Plugin

Smart marketers can place a Facebook share button inside a publication to net more shares and boost its online visibility.

Subscribe Plugin

The subscription process doesn't have to be complicated. Include this plugin anywhere in your publication to turn readers into full-fledged subscribers instantly.

Rating Plugin

Include unobtrusive, star-based rating plugins throughout your content to see what readers think of it.

Feedback Form Plugin

Request written feedback from readers to discover which aspects of your publication are and are not working.

Shoutbox Plugin

Start an online chat with readers and share information in real-time.

Call Me Back Plugin

Need to get in touch? Use this plugin to ask readers for their phone numbers.

Drawings can be incorporated into publications in the form of lines, rectangles, and/or ovals.
