The Brand Book Was Beautiful. The Problem Was It Wasn't Editable.
We had a brand book we were genuinely proud of — 49 pages designed in InDesign, polished, visually precise, and exactly what a brand book should look like. The problem was that our team needed to use it. Internally, in presentations, in onboarding sessions, in client-facing contexts. And none of that was realistic when the document lived only as an InDesign file and a locked PDF.
The goal was clear: recreate the entire brand book in Google Slides, fully editable, so our team could actually work with it. The deadline was tighter — Monday morning, Australia time. That left no room for learning curves, wrong font substitutions, or misaligned layouts. This needed to be done right, not just done.
What I Found Out This Conversion Actually Required
My first instinct was to see if this was something that could be handled quickly with a simple export or a template swap. It wasn't.
InDesign files don't translate cleanly into any other format. The structure is built around a completely different layout engine — master pages, paragraph styles, linked images, embedded graphics, and precision-placed objects that don't map to anything Google Slides understands natively. Getting fidelity in the output means someone has to manually reconstruct the logic of each page.
Then there's the font problem. InDesign projects commonly use licensed or print-specific typefaces that have no direct Google Fonts equivalent. Finding the right substitution — one that preserves hierarchy and visual rhythm without breaking the brand — requires genuine typographic judgment, not just a closest-match search.
And the images embedded in an InDesign file aren't always accessible without opening the source package and extracting assets at the right resolution and format for screen use. That's a step that requires someone who actually knows both tools.
What Doing This Conversion Well Actually Involves
The structural work starts with a full audit of the InDesign source — mapping out master page logic, identifying repeating layout patterns, and categorising each of the 49 pages by template type. A brand book typically contains six to twelve distinct layout structures: cover, section dividers, typography specimens, color swatches, imagery guidelines, usage rules, and so on. Each type needs its own Google Slides master or layout slide, not a one-off manual build per page. Getting the master slide architecture right upfront is what makes the final file actually editable rather than just visually similar. Skipping this step and building page by page instead is the most common mistake, and it produces a file no one can maintain.
The visual mechanics of the rebuild involve matching the original layout grid precisely — typically a 12-column structure with defined gutters and margins — and replicating it inside Google Slides using guides and placeholder positioning. Typography hierarchy needs to be set at the master level: heading sizes tend to sit around 36–40pt, subheadings at 24pt, and body text at 14–16pt, with line spacing and tracking matched as closely as Google's text engine allows. Selecting appropriate Google Fonts substitutions is where most non-specialists lose time — a single wrong pairing breaks the visual language of the brand across every slide that uses that style. Getting it right requires testing across multiple slide sizes and comparing against the original at scale.
Polish and consistency across all 49 pages is the final layer and often the most time-consuming. Brand guidelines enforce strict color palette discipline — typically four to six defined hex values — and every shape, line, icon, and background element needs to hit those values exactly, not approximately. Images extracted from the InDesign package need to be exported at 150–300 PPI for screen clarity, cropped to the same aspect ratios as the originals, and placed with the same visual weight. A single misaligned element or off-brand color on a color swatch slide defeats the entire purpose of the document. Reviewing 49 pages with that level of precision, then running a final consistency pass, takes hours even for someone who does this daily.
Why I Brought in Helion360 to Handle It
Once I understood what a proper conversion actually required — InDesign asset extraction, master slide architecture, Google Fonts matching, palette discipline across 49 pages — it was obvious this wasn't something to attempt without the right tooling and experience already in place. The deadline alone ruled out any learning-curve approach.
I engaged Helion360 to handle the full project end-to-end. That meant working directly from the InDesign source file, extracting all assets at screen-optimised resolution, building the master slide structure in Google Slides, matching the typography hierarchy with appropriate Google Fonts substitutions, and rebuilding all 49 pages with layout fidelity to the original. The whole thing was turned around quickly — delivered in a fraction of the time it would have taken to work through the InDesign-to-Slides pipeline without that depth of experience already built in. There was no back-and-forth on what the brand required; the team read the source material and executed precisely against it.
The Result and What I'd Tell Anyone in the Same Position
What came back was a fully editable Google Slides file that held up against the original brand book side by side. The master slide architecture meant any team member could open a new presentation, apply the brand book layouts, and work within the brand without touching a single raw design file. Onboarding sessions, internal decks, and client-facing materials all pulled from the same editable source. The Monday deadline was met without a scramble.
The brand book went from a static artifact to a living, usable tool — which was the whole point.
If you're looking at a similar conversion and need it handled end-to-end without the weeks of working through InDesign and Google Slides tooling yourself, Helion360 is the team to engage — they delivered fast, handled the full depth of the work, and the output was exactly what it needed to be.
