Export and share

Export an image or source file and understand what a share link contains.

PhysLoom computes and renders in the browser by default. Exporting an image, downloading source, and copying a share link are three different actions.

Export an image

  • SVG is best for websites, articles, print, and later layout work. Text and lines remain vectors.
  • PNG is convenient for messages, screenshot-style delivery, and software that only accepts bitmaps.

An animation exports as a still image, not a video. Pause it or scrub to the desired frame before exporting SVG/PNG; the image keeps that frame’s object positions and in-diagram labels, but not the playback controls or live readouts outside the canvas.

Check the canvas width before export. A label that fits on a wide screen can wrap when placed in a narrow article column.

Download the source

“Download .phys” saves the exact text in the editor. It is readable, editable model source, not a project container with images or extra metadata. Keep both the .phys source and an SVG export for important work.

The source preserves animate duration=4s speed=2: a four-second experiment played at twice normal speed. The current pause position is not stored in the .phys file.

The current share link stores a compressed model in the URL instead of uploading it to a PhysLoom server first. Anyone with the complete link can open the model, so do not include secrets, personal information, or unpublished questions.

A share preserves the experiment duration and speed in the source. It opens at the initial frame, ready to play, rather than restoring the sender’s pause position. Export SVG/PNG to share a particular frame instead.

When the link is too long, send the .phys file instead. If hosted storage is added later, the documentation will name its location, retention period, and deletion route.

Use a diagram in an article

Prefer an exported SVG for ordinary articles and lessons. It does not require JavaScript and works well on the web, in print, and in later layout work. Use the Beta embed page only when readers need to play an animation.

The “Copy Markdown” button at the top of every documentation page copies clean Markdown, ready for notes, a repository, or another editor.
