One Design, Two Platforms: Turning Claude Design Work Into LinkedIn and Instagram Carousels in a Single Export

Carousels quietly became the highest-performing format on both LinkedIn and Instagram. They stop the scroll, they earn multiple impressions per post as people swipe, and both algorithms reward the extra dwell time. If you're publishing content in 2026, you're probably publishing carousels.

And if you're making those carousels in Claude Design, you have discovered the catch: the two platforms don't just want different sizes. They want different file types entirely.

The same carousel is two different deliverables

Here is the part that surprises people the first time:

Instagram carousels are images. You upload up to 20 individual image files, typically 1080 × 1350 or 1080 × 1440 portrait, and Instagram stitches them into the swipeable post.

LinkedIn carousels are PDFs. There is no native carousel format at all. The trick everyone uses is uploading a multi-page PDF as a document post, and LinkedIn renders each page as a swipeable slide. The LinkedIn carousel guide covers the format in detail.

So one piece of content, say a 7-slide breakdown of your product or a listicle of tips, has to leave your design tool twice: once as a stack of correctly sized PNGs, and once as a single multi-page PDF.

Where Claude Design leaves you

Claude Design is genuinely great at making carousel content. Slide Deck mode with a design system produces consistent, on-brand slides faster than any traditional editor. The problem starts when the slides are done.

The export menu gives you a PDF, which sounds promising for LinkedIn, until you notice the pages can come out at document proportions rather than the square or portrait shape a carousel needs. And for Instagram the PNG export works one artboard at a time with no platform size preset, so you're downloading seven slides one by one and checking that each came out at 1080 × 1350 with the same framing.

Multiply that by two platforms and every revision, and a ten-minute design session turns into an hour of export housekeeping.

The Social Pack: both platforms in one go

This exact workflow is why Renda has a Social Pack export. Instead of choosing one format and doing the rest by hand, you get everything at once:

1. Export your project from Claude Design (standalone HTML or zip).
2. Drop it into Renda and choose Social Pack.
3. Download one bundle containing numbered PNGs at your slides' own size (so design them at an Instagram carousel size), one per slide and ready to upload in order, plus a multi-page PDF of the same slides, ready to post to LinkedIn as a document.

Same source, both deliverables, one pass. Because everything is rendered from the design's actual code rather than captured off a screen, every slide is pixel-sharp and identically framed. Slide 4 lines up with slide 3, which is precisely the thing manual screenshots always get slightly wrong. The social pack guide walks through the full bundle, including what happens to standalone graphics in the same file.

Change one word in the design? Re-export the pack and both platforms are updated together. No re-cropping, no drift between versions.

A workflow worth stealing

If you want the repeatable loop, this is it:

1. Draft in Claude Design using Slide Deck mode with your design system, so every carousel stays on brand automatically.
2. Write for the swipe. First slide is the hook, one idea per slide, last slide is the call to action. This structure works identically on both platforms, which is exactly why exporting both at once makes sense.
3. Run the Social Pack and schedule the PNGs to Instagram and the PDF to LinkedIn.

One design session, two platforms covered, zero screenshots.
