Frequently Asked Questions

Everything you need to know about drawing on PDFs online.

How do I draw on a PDF for free online?

Upload your PDF to this page, select a drawing tool (Pen, Marker, or Highlighter), choose your color and stroke size, then draw freely on the page. When you are done, click Download PDF to save your annotated file. No sign-up or payment needed.

Are my PDF files sent to a server?

No. QwikDraw runs entirely inside your browser using JavaScript. Your PDF file is loaded into browser memory only — it is never transmitted over the internet to any external server. This makes it completely safe for confidential documents.

Will the downloaded PDF have a watermark?

No watermarks are added at any point. Your downloaded file will contain only your original PDF content and whatever drawings you made — nothing else is added.

Can I draw on all pages of a multi-page PDF?

Yes. Use the page navigation arrows to move between pages. Each page stores its annotations independently. When you click Download PDF, all annotations from all pages are embedded into the final document.

What is the difference between Pen, Marker, and Highlighter?

The Pen tool creates smooth, precise strokes at full opacity — ideal for signatures and writing. The Marker tool produces flat-ended, bold strokes for clear annotations. The Highlighter tool draws at reduced opacity with a wider default stroke, making text show through underneath.

Does this work on iPhone, iPad, or Android?

Yes. QwikDraw works in any modern browser including Safari on iPhone and iPad, and Chrome or Firefox on Android. Touch drawing is fully supported, so you can annotate PDFs using your finger or a stylus.

Can I undo my drawing mistakes?

Yes. The Undo button removes the most recent stroke, and you can undo as many strokes as needed. Use Redo to bring back undone strokes. Keyboard shortcuts Ctrl+Z (undo) and Ctrl+Y or Ctrl+Shift+Z (redo) also work.
