Turn One Claude Design into a Full Social Pack

You build one design. Then you go to post it, and every platform wants something different. LinkedIn wants a portrait PDF you upload as a document. Instagram wants square or 4:5 PNGs, one per slide. X wants square or 16:9. The standalone graphic you made for the blog header needs its own crop. One idea, five formats, and you are the one re-exporting and re-cropping the same Claude Design file over and over.

This is the cross-posting tax, and most creators pay it manually. This guide is about skipping it. The short version: one design should become everything you need to post, in a single pass. That bundle is what we call a social pack.

The one-design, five-platforms problem

The trap is that the design is the easy part now. Claude Design will give you a sharp six-slide carousel in a few minutes. The friction moved downstream, to distribution. The same carousel that looks great in the Claude canvas has to leave as four or five different file sets if you want it live everywhere.

And the platforms genuinely disagree with each other. It is not that you are being fussy. LinkedIn treats a carousel as a paginated document. Instagram treats it as a sequence of separate images. X treats it as up to four images in a tweet. Stories want a tall full-bleed frame. None of them accept the format the other one wants.

What each platform actually needs

Before you can repurpose anything you have to know the targets. Here is what each placement expects from the same underlying design.

One design, read five different ways. That is the whole problem in one table.

The slow manual workflow

Here is how most people do it today, and why it quietly eats an afternoon.

You export the design, then open it in an image editor or screenshot it slide by slide. You crop each slide to square for Instagram. You crop it again to 16:9 for X. You stitch the slides into a PDF for LinkedIn, hoping the page order holds. You go back and remove the arrows, page counters, and pip dots that were on-canvas navigation and have no business being in the final image. Then you do it again for the next post.

The Canva round-trip is the other common route, and it is not much better. You import, you nudge frames to fit each platform, you export per size, and you need a paid Canva subscription to do it cleanly. It is the same re-cropping, just inside a different tab.

Neither route scales. The work is mechanical, repetitive, and exactly the kind of thing that should happen once, automatically, from the file you already have.

What a social pack is

A social pack is the opposite of doing it five times. You upload the design once, and you get back every asset you need to post, sized and named and ready, in a single pass.

Concretely, when you drop a Claude Design export into Renda's social pack, one file comes back as all of this at once:

• Each carousel as a multi-page LinkedIn carousel PDF, slides in order, ready to upload as a document post.
• Every slide also exported as its own square or portrait PNG, so the same carousel is ready for Instagram or X without any extra work.
• Any standalone graphics in the design rendered as their own PNGs, cropped to themselves rather than to the whole canvas.

Everything is sized from your actual design. The on-canvas chrome (arrows, page counters, pip dots) is stripped out, so what you post is the design and nothing else. Slides stay in deck order, and the PNGs render at 2x so they stay crisp on retina screens.

The one-drop workflow

The point of a social pack is that the distribution step stops being a task. The loop is short.

Build the carousel and any one-off graphics in Claude Design. Export the standalone file. Drop it into the social pack. Download the bundle. You now have the LinkedIn PDF, the per-slide PNGs for Instagram and X, and the standalone graphics, all from one upload, no cropping and no per-platform re-export.

From there you just post. LinkedIn gets the PDF as a document. Instagram and X get the PNGs. The blog gets its standalone graphic. The thing that used to be an afternoon of file wrangling is now the gap between two coffees.

Who this is for

If you post the same idea everywhere, this is for you. Solo creators and founders who write one carousel and want it on LinkedIn, Instagram, and X without rebuilding it three times. Social media managers running a content calendar where every post has to ship to four placements. Agencies handing a client a finished pack rather than a single file the client then has to figure out how to use.

The common thread is volume of placements, not volume of ideas. You do not need more designs. You need the one design you already made to show up correctly in every feed it is going into.

Renda's free tier covers 10 renders a month with no account needed, so you can run a real post through the social pack before deciding anything. Pro is £4.99 a month when you are doing this every week.
