Whiteboard
Draw diagrams and lay out pages, then save a PDF that stays editable.

Kept on this device only — never uploaded, and no account. Clearing your browser data removes them.
Shapes

Flowchart
Arrows and callouts
Lands in the middle of the view, in your current colours. Double-click a box, circle or diamond to put text inside it.
Templates
Dropped onto the canvas with the arrows already joined up, so moving a box moves what connects to it.
Pages
Each page you add becomes a page of the PDF, top to bottom. Add none and you get the single page this has always produced.
Saving produces a PDF that is still a drawing: it opens in any PDF reader, and dropping it back on Open PDF here recovers everything so you can keep working. Keep that file and you keep the editable version.
What to know about Whiteboard
A hand-drawn canvas that keeps your drawings on this device and saves them as a PDF that is still a drawing — it opens in any reader, and dropping it back here recovers everything. Add pages and each one becomes a page of the PDF, or open an existing PDF and mark it up.
Most free drawing tools give you exactly one canvas. Start something new and whatever was there is gone, and keeping several means exporting files and organising them yourself. That is usually the thing the paid tier sells back to you.
Here the library is the tool. Every drawing you make is kept, named and listed, and switching between them takes a click. They live in this browser on this device — no account to make, nothing uploaded, nobody else able to see them. The honest cost of that is the same as the benefit: they do not follow you to another machine and nothing is backed up, so a drawing that matters should be saved out.
Which is where the PDF comes in, and it is the part that is genuinely different. Saving does not flatten your drawing into a picture. The artwork is written as real vector shapes, so the page is sharp at any zoom and prints properly, and the editable drawing is attached inside the very same file. One file does both jobs — the one you email to somebody, and the one you open next week to change the diagram. Bring it back to this page and everything returns exactly as you left it, on any computer, with nothing to sign into.
That idea is not new. An Adobe Illustrator file is a PDF with the native data tucked inside it, which is what "Create PDF Compatible File" has always meant. It fits here better than inventing a private format would: a PDF site whose save format is a PDF, and nothing proprietary standing between somebody and their own work.
The editor is Excalidraw, which is open source under the MIT licence, and the hand-drawn look is the point rather than a limitation — a sketched box reads as a proposal, and a crisp one reads as a decision. What has been built around it is the library, the PDF that stays editable, and the guarantee that none of it needs a network.
That last part is enforced rather than promised. The fonts are served from this site instead of being fetched from elsewhere, the sharing and template features that would call out to other servers are removed rather than left to fail, and the page's own security policy blocks outbound connections regardless. Switch your connection off after the first visit and every part of this still works.
How to draw and save as PDF
- 1
Start drawing
Pick a shape, an arrow or the pen and draw. Everything is saved to this device as you go — there is no save button to forget.
- 2
Keep several on the go
New starts a fresh canvas without losing the last one. The list on the left holds every drawing you have made here.
- 3
Save as PDF
The PDF holds the artwork as vectors, so it stays sharp at any zoom, and it carries the editable drawing inside it.
- 4
Come back to it later
Open PDF takes a file this tool saved and restores the whole drawing, on any device, with nothing to sign into.
What Whiteboard accepts and produces
- Input
- Nothing to start. A PDF this tool saved earlier reopens as an editable drawing; any other PDF opens as pages to draw on.
- Output
- A PDF holding the drawing as real vectors, with the editable version attached inside the same file. One page per page you added, or a single page if you added none.
- Limits
- Drawings live in this browser on this device. They are not synced, not shared and not backed up — clearing your browser data removes them, so save anything you want to keep.
- Offline
- Yes, entirely, after your first visit.
Why Whiteboard here
- Keep as many drawings as you like — most free whiteboards give you one canvas
- Saved PDFs stay editable: one file to send and to work on, not two
- Vector output, so a diagram stays sharp printed or zoomed
- Nothing is uploaded, there is no account, and no one else can see your board
- Works with the network switched off once the page has loaded
- No watermark and no limit on how much you can draw
Where your file goes
Nowhere. This tool runs inside your browser, and the page is served with a policy that forbids it from sending your document anywhere. You can confirm that yourself: open your browser’s developer tools, watch the Network tab, and process a file.
Questions
Where are my drawings stored?
In this browser, on this device, and nowhere else. There is no account and no server copy, which also means they do not follow you to another computer and are not backed up. Clearing your browser data — or using a private window — removes them. If a drawing matters, save it as a PDF: that file is yours, it opens anywhere, and it restores the editable version when you bring it back here.
What makes the saved PDF different from a normal export?
It carries the drawing twice. The artwork is drawn as real vectors so the page looks right in any PDF reader and stays sharp at any zoom, and the editable version is attached inside the same file. That means one file instead of the usual two — the one you send and the one you can still work on. Adobe Illustrator has done the same thing for years: an .ai file is a PDF with the native data embedded.
Can I edit a PDF I saved on a different computer?
Yes, as long as it is the PDF this tool wrote. Open the whiteboard, choose Open PDF and pick the file — the drawing is rebuilt from the copy attached inside it. That is the closest thing to sync here, and it works without an account because the file is doing the carrying rather than a server.
Will another PDF editor break the editable part?
It might. The editable drawing lives as a file attachment inside the PDF, and some editors drop attachments when they re-save. Viewing, printing and sharing are all safe; it is re-saving from another tool that carries the risk. If you plan to edit the drawing again, keep the file this tool produced rather than a version another program has written over.
Does it work without a connection?
Yes, once the page has loaded the first time. The editor and its fonts are served from this site rather than fetched from anywhere else, so after that first visit the whole thing runs from your device — drawing, saving to the library and producing the PDF included. That is also why nothing you draw can reach a network.
Can I make a multi-page document, not just one diagram?
Yes. Add a page — A4 or Letter, portrait or landscape — and a frame that size appears on the canvas. Draw inside it, add more pages below, and saving produces a PDF with one page per page you added, in the order they run down the canvas, each at the size you chose. Add no pages and you get the single page this has always produced, so sketching is unaffected. It is the part that makes this a way of laying out a document rather than a way of drawing one picture.
Can I write on a PDF somebody sent me?
Yes. Open a PDF to draw on and each of its pages arrives on the canvas inside its own page frame, ready to be annotated with arrows, highlights, boxes or handwriting. Saving gives you back a PDF with the same page count and page size it arrived with, your marks drawn on top. Up to twenty pages, which is the point past which a document is something to read rather than something to mark up. The file is rendered on your device, like everything else here.
Can several people draw on the same board together?
No, and that is a deliberate limit rather than a missing feature. Live collaboration needs a server relaying what everyone draws, which would mean your board leaving your device — the one thing nothing on this site does. If you need a shared board, use a hosted tool that is honest about storing your work. If you want to send somebody a drawing, the PDF does it.
