Sharing Code with UniPreview

URL-based sharing

Use Share to generate a link that encodes your project directly in the URL. Anyone who opens the link sees the same code and the same live preview - no account or server-side save is involved. Very large projects may be too big to encode this way; UniPreview will tell you if a project is too large to share as a link.

QR code sharing

From the same Share dialog, generate a QR code for the link - useful for sharing on a phone, presenting in a meeting, or printing on a handout. QR codes have a lower size limit than plain links, so very large projects should be shared as a link instead.

Embedding

Share also offers an embed snippet you can paste into another web page to show a live UniPreview editor with your code pre-loaded.

Privacy note

Your code lives in the URL itself (or the embed snippet) - UniPreview does not keep a separate server-side copy of shared projects. Keep that in mind before sharing a link that contains anything sensitive, since anyone with the link can read the code in it.

Working with large files

UniPreview recommends keeping individual files under about 500KB for the best editor performance; very large files may be blocked from preview with a "file too large" notice, and will not fit into a shareable URL or QR code.

Saving a local copy instead

If you just want a copy on your own machine rather than a link to send someone, use "Download file" to save the current tab, or "Copy code" to copy it to your clipboard.
