How to Turn a Claude Design into PNGs

You have a Claude Design open. You want PNGs out — one per slide, sized for Instagram or Twitter or LinkedIn, ready to post. This is the short, direct answer.

The three ways to do it

There are three real options, depending on how many PNGs you need.

1. Use Claude Design's own PNG export

Claude Design can now export a single artboard as a PNG at 1x or 2x, from the artboard's download menu on the canvas or from Share, Export, PNG (image) inside a Claude conversation. Works for one slide, gets slow at three. There are no platform size presets, so the PNG is whatever size the artboard is, and a multi-slide carousel means one trip through the menu per slide.

Use this when you need one or two PNGs and the artboard is already the right size.

2. Use the built-in Send to Canva export

Claude Design ships with a Send to Canva button. From Canva, you can export individual slides as PNG. But the round trip adds two more screens to your workflow, and the export sometimes shifts your layout because Canva converts the design rather than rendering it faithfully (designs that are not slide decks import as a basic code design with limited editing).

Reasonable if you want to keep editing in Canva. Slow if you only want the PNGs.

3. Use Renda

Renda is the tool we built for this exact step. Drop your Claude Design file, pick the platform you want PNGs for, get clean per-slide PNGs at the right dimensions, the whole carousel in one go. No screenshots, no Canva round trip, no cropping. Five free PNGs a month (each slide counts as one), no card required to try.

Why Renda works on any design

Most screenshot-and-crop tools assume your design follows a template — same fixed canvas, same slide markers, same expected layout. Real Claude Designs do not look like that. One day you build a square carousel with arrow navigation. The next day a long-scrolling page. The next, a portrait pitch deck with pip dots.

Renda's AI looks at each design separately and figures out what to do. It detects how many slides there are, hides whatever navigation UI Claude added, picks the right capture region, and renders each slide at the platform dimensions you asked for. You do not configure anything. You drop the file and pick a preset.

The steps

1. Export from Claude Design. Click Export in the top right (Share, then Export inside a Claude conversation) and download standalone HTML or the project .zip.
2. Drop the zip on Renda. The site is one page — there is no setup.
3. Pick a platform preset. Instagram 4:5, Instagram square, Story, Twitter, LinkedIn, PowerPoint. Each one renders at the platform's exact shape, at 2x for sharpness.
4. Download the PNGs. Multi-slide designs come back as one PNG per slide, numbered in order so you can drag them straight into the platform.

From file to ready-to-post PNGs in about a minute.

What dimensions do you actually need?

The short version, for the platforms that matter most:

Pick the preset that matches and Renda renders that shape at 2x (a 1080 × 1350 design comes out at 2160 × 2700), so there is no resizing in Photoshop after. There is no 3:4 preset: design the artboard at 1080 × 1440 and use Auto-detect, which keeps your design's own size.

The short version

For one PNG, use Claude Design's own export. For repeated work or anything past one slide, use a renderer like the free Claude Design to PNG converter. Renda is the one we built for this; it works on any Claude Design without you configuring anything, and the free tier covers most personal use.
