How to use

Start drawing right away — no sign-up needed. Pick a shape from the toolbar (rectangle, ellipse, diamond, arrow, text), drag it onto the canvas, and connect shapes with arrows that stay attached when you move things around. Already have a diagram elsewhere? Click Import and drop in a .drawio, .xml, or .excalidraw file. When you are done, give the board a title and click Save & Share: you get a permanent preview link to send to anyone, plus a source-file URL for downloading the board back. Export at any time as a PNG image, an SVG, an .excalidraw file, or a .drawio file you can reopen in draw.io.

Why use this tool

Most diagram tools make you create an account before you can draw a single box, and the good ones put export behind a paywall. This whiteboard opens straight into an empty canvas, keeps everything in your browser while you work, and lets you save and share with one click — anonymously if you want. It is built on Excalidraw, the open-source hand-drawn-style canvas, so sketches look deliberately informal, which is exactly right for architecture diagrams and flowcharts that are meant to be discussed rather than admired. The part that is genuinely rare: two-way draw.io compatibility. You can bring an existing .drawio diagram in, redraw it here, and take it back out — so this is a viewer and a quick editor for draw.io files, not another format silo.

FAQ

Do I need an account to use the whiteboard?

No. You can draw, export, and even save a shareable link without signing in. Signing in adds two things: your boards show up in the Dashboard so you can reopen and re-edit them, and you can insert images (which get uploaded to the image host).

Can I import a draw.io file?

Yes. Import accepts .drawio and .xml files, including the compressed ones draw.io produces by default. Basic shapes (rectangles, ellipses, diamonds), text, and connectors with their labels, colors, line widths, and dash styles are mapped over. Shapes outside that set — swimlanes, containers, custom stencils — are simplified to rectangles with their labels kept, and the tool tells you how many were simplified rather than silently dropping them.

Can I export back to draw.io?

Yes. Export → draw.io file produces an uncompressed .drawio file that opens directly in draw.io or diagrams.net. Shapes, positions, colors, connectors, and labels come across; the hand-drawn stroke style does not, since draw.io has no equivalent.

Who can see a board I save?

Anyone with the link. Saved boards are not indexed by search engines, but the link itself is public and unguessable rather than password-protected — so do not put credentials or other sensitive information on a board you share.

What image formats can I export?

PNG for pasting into docs, chat, and slides, and SVG when you need a resolution-independent vector you can scale or restyle later. Both include the canvas background and a small padding margin.

Is my drawing sent to a server while I work?

No. Editing, importing, and exporting all happen in your browser — draw.io files are decompressed and converted client-side. Data reaches the server only when you click Save, and only then to store the board behind your share link.
