What export and sharing options does UMLet offer?

Updated

UMLet exports diagrams to EPS, PDF, JPG, SVG, and the system clipboard, and version 15.0 added high-resolution export. The fastest sharing path is pressing C to copy the current diagram straight to the clipboard; the file formats are better when you need to embed a diagram in a document or hand it to someone who doesn't use UMLet.

Export formats at a glance

Format Best for Notes from the site
EPS Print workflows and LaTeX/vector pipelines Listed as a supported export
PDF Documents, reports, sharing with anyone Listed as a supported export
JPG Quick previews, chat, slides Raster, so it scales less cleanly
SVG Web pages and further vector editing Listed as a supported export
Clipboard Pasting into another app immediately Triggered with C

High-resolution export was introduced in UMLet 15.0, so if crisp output matters, use a 15.0-or-later build rather than an older one.

Copy a diagram to the clipboard

This is the option to reach for when the diagram is going into a chat, a ticket, or another editor right now.

  1. Open or create the diagram in UMLet.
  2. Make sure the diagram canvas has focus (click on it if needed).
  3. Press C.

Expected result: the diagram is copied to the system clipboard, and you can paste it into whatever application you're using. No file is written to disk, which is why this is the quickest route for casual sharing.

Export to a file

Use a file export when the diagram needs to live somewhere durable or be embedded in a document.

  1. Build the diagram on the canvas.
  2. Use the export function and choose EPS, PDF, JPG, or SVG.
  3. Save the file and open it in the target application to confirm it looks right.

The site lists these four formats as the export set; it does not document per-format settings such as DPI or page size, so treat the exact output options as something to check in your installed version.

Choosing between clipboard and file export

  • Clipboard (C) — fastest, no file management, ideal for pasting into a message or a document you're already editing.
  • SVG or EPS — pick these when the diagram will be scaled, printed, or edited further as vector art.
  • PDF — pick this when the recipient just needs to view or print it without editing.
  • JPG — pick this for a lightweight raster image where scaling isn't a concern.

Practical notes

  • The site's quickstart lists C for clipboard copy, +/- or Ctrl+mousewheel for zoom, and Shift to avoid sticking relations — zooming before you export or copy affects what you capture, so frame the diagram first.
  • UMLet is described as free and open-source, with a stand-alone app for Windows, macOS, and Linux, an Eclipse plugin, a web app (UMLetino), and a Visual Studio Code extension. Export behavior may differ slightly between these builds, so verify the format you need in the one you actually use.
  • The site mentions sponsorship via GitHub, Patreon, and PayPal, but that is unrelated to export or sharing features.
