Invite up to three people. You approve who joins.
Keep devices awake and pages open. Sessions last two hours, with one free 30-minute extension. Your local board stays when sharing ends.

One active host session per network; end it before creating another. Approve guests, switch editing on or off, or remove them above. Drawings and images use encrypted browser connections. The connection service helps browsers find each other. Board content travels directly between approved browsers; URLtoFile does not store your board. Save an editable backup to continue elsewhere.

Curious how we made this private?
- Drawings, images and text are processed in your browser. Your draft is saved on this device.
- Sharing is off until you start it. We store only a two-hour invitation and security metadata; no board content or images in Blob.
- The host approves guests. Board content travels directly between approved browsers over encrypted WebRTC. Signaling and STUN services exchange connection information.
- End the invitation to stop new access. Guests may keep copies they already saved; network services and your device still have their own security limits.
Saved on your device. Optional sharing sends encrypted content to approved guests.
Put feedback on the picture.
Drop a screenshot exactly where you need it. Move it, resize it freely and mark your changes with a pen or a text note.
Bring three people into the idea.
Share a link or QR invitation, approve guests and control who can edit. Named cursors help everyone follow along.
How to use Whiteboard
- Start drawing, or paste an image with Ctrl+V / Command+V. Drop image files anywhere on the sheet.
- Choose a pen, ink color and tip size. Add text or pages; select images to move and resize them.
- Prepare a PDF of all pages, or use File to save an editable board. Share is optional.
Draw online, annotate images and save a PDF
Use this free browser whiteboard for handwritten notes, screenshot feedback, lesson explanations and project planning. Pen, fine pen, marker and highlighter tools work with a mouse, touch or stylus. Choose blank, dotted, lined or grid paper. No signup is needed to start drawing.
Paste a screenshot onto your whiteboard
Copy an image using Copy image or your screenshot tool, then press Ctrl+V on Windows or Command+V on Mac. You can paste while on this page unless a text field is focused. File also includes Paste image from clipboard, where supported by your browser. Drag a PNG, JPG or WebP file onto the sheet to place it at that point. Select the image to move it; drag its blue corner to resize width and height freely. Copy image address copies a URL, not an image.
Explain an idea without switching tools
Paste a screenshot onto the board, select it to move or resize it, then use a pen or highlighter to annotate it. Add editable text for labels and instructions. For a lesson, keep each topic on a separate page and export the pages together as a PDF.
A practical workflow for feedback
- Add a PNG, JPG or WebP image using Upload, drag-and-drop or paste.
- Use Select to move objects. The selection controls resize images, edit text, duplicate objects and change their order.
- Use File to save an editable .urlboard backup. PDF is for sharing a finished view; the board file is for continuing your work.
Local work and optional collaboration
Your draft is stored in this browser on this device. Starting a shared session creates a two-hour invitation. The host approves up to three guests, can pause their editing or remove them, and can share the invitation as a QR code. Only one host session is allowed per network; end it before starting another. Named cursors show where participants are working. Drawing, erasing and object movement appear while approved participants work, before they release their pointer; finished edits are then synchronized. Board content travels over encrypted browser connections; only invitation metadata is stored on our server. Hosts see an Accept or Reject notification when someone requests access. Copy a ready-to-send invitation message, or display a QR code for scanning. On phones, turn sideways for landscape fullscreen drawing. Use one finger for ink and two fingers to zoom or pan. The host must remain connected. Some school, office and mobile networks block direct connections. Direct setup retries up to three times. No board relay is used; if your network blocks peers, try another network. Connection help shows the setup state. There is no server copy of the drawing.
Whiteboard keyboard shortcuts
V selects objects, P selects the pen, E selects the eraser and T adds text. Ctrl/Command+Z undoes your change, Shift+Ctrl/Command+Z redoes it, and Ctrl/Command+S saves an editable board file when the editor is focused. Delete removes the selected object. On touchscreens, draw with one finger and zoom or pan with two fingers.
When something does not work
If pasting an image fails, save it as PNG, JPG or WebP and use Upload. Very large images are resized for the board. If local draft storage is full or blocked, save an editable board file. If a peer connection fails, check that the host is online and try another network; the local editor remains available. PDF export renders the board as images, so handwriting and text are not searchable in the PDF.
About this tool
How do I use the whiteboard on my phone?
Turn your phone sideways for fullscreen drawing. In portrait, a rotation prompt offers Exit full screen. Use one finger to draw and two fingers to zoom or pan. Tools hide after a drawing gesture; the top-right Show tools icon restores them. Hide tools sits in the toolbox. The normal page remains usable in portrait.
Can I paste an image or text onto the whiteboard?
Yes. Copy an image, then press Ctrl+V or Command+V on this page outside a text field. File includes a Paste image from clipboard action on supported browsers. Images can also be uploaded or dragged onto the canvas. Copied plain text opens an editable text box. Copying an image URL alone does not import its image.
Are my images or drawings uploaded to Vercel Blob?
No. Images and drawings stay in browser storage. When you enable sharing, copies are sent to approved participants over encrypted WebRTC, with a relay fallback where configured. Our server stores invitation metadata, not images, drawings or board files. A signaling service exchanges connection information.
How many people can collaborate, and for how long?
A session supports four people including the host. Guests must be accepted by the host, who must stay connected. Invitations expire two hours after creation, with one free 30-minute extension available to the host or an approved guest. Both sides see the countdown. Expiry disconnects sharing and preserves your local board. Save a backup and start a new shared session to continue. Keep devices awake and pages open. The timer discourages prolonged misuse. Expiry cannot remove files or copies participants already saved.
Can I reopen the board later?
Up to five recent drafts are saved in this browser when storage is available. File, Recent local drafts opens an independent copy. For a portable backup, use File, Save editable board, then reopen the .urlboard file. Clearing browser storage removes the local draft. A PDF preserves the appearance but is not an editable board backup.
What are the limits?
Up to 20 pages, 300 objects and 40,000 stroke points per page, and 10 images per board. Image input is limited to 12 MB and 40 megapixels; imported images are resized to at most 1600 pixels on the longest edge. Direct collaboration is not guaranteed on restrictive networks.
