How to export your drawing as a PNG

· updated

Hyperdraw exports the composited canvas: every visible layer, in order, flattened into a single image and saved as a lossless PNG.

The quick way, from the canvas: Context Menu

You can right-click the canvas (or long-press on mobile), then choose:

  • Save Visible Canvas - flattens the visible layers into the gallery (no download). From there you can download it later, view it full-screen, or reuse it on the canvas.
  • The Snapshot & Download action does the same and saves the PNG to disk.

The context menu path bakes in the document background colour if you’ve set one; if your document background is transparent, so would the the export be.

The easy to remember way: Snapshot & Download

  1. Open the ☰ menu (top-left) and choose Download ….
  2. In the panel, click 📸 Snapshot & Download.

That’s it. Hyperdraw flattens all visible layers, adds the result to your gallery, and downloads the PNG to your browser’s downloads folder. The file is named hyperdraw-<date>-<id>.png.

This path keeps transparency: anywhere your layers are transparent, the exported PNG is transparent too - no background is painted in.

While browsing or reviewing in full-screen mode, clicking the Download button in the top toolbar will allow you do do it without interrupting the flow. The image is saved to your downloads folder as-is. (The same button works for video, audio, 3D models, and text assets - each downloads in its own format.)

Downloading many at once

The same ☰ menu → Download … panel lets you grab a batch:

  1. Select the assets you want (or Select All).
  2. Choose Download Selected as ZIP for one archive, or Download Selected (individual) to save each file separately.

ZIP filenames inside the archive follow the same hyperdraw-<date>-<id>.png pattern, and duplicates are automatically numbered.

Good to know

  • Always PNG, always lossless. The composite is encoded at full quality - ideal for screenshots, sharable references, and anything with hard edges.
  • Exports match your document size. There is no resolution cap; the PNG is produced at the canvas’s own pixel dimensions.
  • Hidden layers are skipped. Only visible layers are composited, in their stacking order, honouring each layer’s opacity and blend mode.

For photographs or AI-generated imagery, a lossy format is often a better size trade-off - but Hyperdraw’s canvas snapshot export is PNG only, so we preserve all the pixels that were in the source image.

What about imported JPEGs (or WebP, GIF…)?

Downloading an imported or generated asset is different from a canvas snapshot: Hyperdraw never re-encodes it. You get the original bytes, unchanged - a JPEG stays a JPEG, a WebP stays a WebP.

There is one wrinkle to know about:

  • The single-image Download buttons (full-screen toolbar and the per-item button in the Download panel) always name the file …​.png, even when the bytes are JPEG/WebP/GIF. The contents are untouched and any image viewer will still open them, but you may want to correct the extension by hand.
  • The Download Selected as ZIP path gets the name right: each file is labelled by its true type (.jpg, .webp, .gif, …) from the asset’s content type.

So if you care about correct file extensions for a batch of mixed-format imports, prefer the ZIP download.
