Portals lets you export your work in several formats depending on what you built and where it needs to go. Design mode artboards support PNG, PDF, and ZIP. Compose mode slides export as PDF or PPTX. Use the export panel in the toolbar to access all options from a single place.
Use PDF when sharing polished work with clients — it preserves layout fidelity across devices. Use PNG for quick sharing in chat, social, or presentations where you need a flat image.

​
PNG screenshot

PNG is the fastest way to get a pixel-accurate image of your canvas or a specific artboard.
1

Select what to export

In Design mode, click the artboard you want to export to select it. To export the entire canvas, deselect everything by clicking the canvas background.
2

Open the export panel

Click the Export icon in the toolbar (or open the toolbar and navigate to the Export section).
3

Choose PNG

Select PNG from the format list. PNG supports transparency and is ideal for designs with non-white backgrounds.
4

Set scale and quality

Adjust the Scale multiplier if you need a higher-resolution output (for example, 2× for retina/HiDPI displays). Quality is lossless for PNG.
5

Export

Click Export. The file downloads as <artboard-name>.png.
PNG export rasterizes the artboard at the scale you choose. Elements that rely on remote resources (custom fonts, externally-hosted images) may not render if those resources are unavailable or blocked. Portals attempts to load cross-origin assets automatically where possible.

​
PDF

PDF export renders each slide or artboard as a page in a landscape A4 document.
1

Open the export panel

In Design mode or Compose mode (slides), click Export in the toolbar.
2

Choose PDF

Select PDF from the format list.
3

Export

Click Export. Each artboard or slide becomes a landscape A4 page. The document is saved as <title>.pdf with Portals listed as the creator in the PDF metadata.
For HTML and web artboards, each slide is rasterized at high resolution before being embedded in the PDF. This produces a high-quality image-based PDF rather than a vector PDF — text inside the exported image is not selectable.

​
ZIP project bundle

For web artboards in Compose mode, Portals can export the generated application source as a ZIP archive containing the full HTML, CSS, and JavaScript. This is useful when you want to host or edit the app outside of Portals.
1

Open a web artboard in Compose mode

Switch to Compose mode with a generated app artboard active.
2

Click the download button in the app viewer

Inside the App Viewer card, click the Download ZIP button. Portals bundles the app source.
3

Save the archive

The file downloads as <app-name>.zip. Extract it to get the standalone web application.

​
PPTX slides

Portals can export slide presentations to PPTX format. Each slide is captured as a high-resolution PNG image and packaged inside a PowerPoint-compatible ZIP structure.
1

Build your slides in Compose mode

Use Portal Agent or the Slides canvas to create your presentation content.
2

Open the slide export options

Click Export in the toolbar and select PPTX (PowerPoint).
3

Confirm and download

Portals renders each slide at high resolution, packages the images into a .pptx file, and downloads it as <presentation-title>.pptx.
PPTX export is currently in active development. If you select PPTX export and the feature is not yet available in your build, Portals will automatically fall back to PDF and notify you. The exported PPTX is compatible with Microsoft PowerPoint, Google Slides, and Apple Keynote.

​
ScreenshotCapture — grab any canvas region

ScreenshotCapture lets you drag a selection rectangle over any part of the canvas and send the captured region directly to the floating AI chat for analysis or further generation.
1

Enter screenshot mode

Click the Camera icon in the toolbar to activate ScreenshotCapture mode. The cursor changes to indicate capture is ready.
2

Drag to select a region

Click and drag over the canvas area you want to capture.
3

Send to AI

The captured image is automatically attached to the Portal Agent chat. You can then ask Portal Agent to analyze, describe, or iterate on the captured content.
4

Cancel

Press Escape at any time to exit screenshot mode without capturing.

​
Export quality and scale

Scale multiplier

A scale of 1 exports at the artboard’s native resolution. Use 2 for retina-quality output or when you need to zoom in on exported images without visible pixelation.

Canvas rasterization

All exports (PNG, PDF, PPTX) rasterize the canvas. The capture pipeline automatically strips selection handles, snap guides, and other workspace UI elements before rendering, so only your design content appears in the export.
