Snip or Drop It
Snip any part of your screen: on Windows press Win+Shift+S then Ctrl+V; on a Mac press Cmd+Ctrl+Shift+4 then Cmd+V. Or drop an image or a PDF onto the page and pick the page you want.
Quick markups. Without the heavy PDF software.
You know the moment. A colleague needs one detail circled, a client needs a quick note on a drawing — and you’re opening a PDF suite with a hundred buttons. CADsnip is the quick way: snip it, mark it up, stamp it, send it.

Questions
Is CADsnip free?
Yes. All the tools are free to use.
Are my drawings uploaded anywhere?
No. Images and markups stay in your browser on your device.
Does it work with PDFs?
Yes. Drop a PDF and pick a page to mark up.
Which browsers does it work in?
Microsoft Edge and Google Chrome on Windows. Other browsers are not fully tested yet.
Can I edit a markup later?
Yes. Save the sketch as a .cadsnip file, open it again later and every markup is still editable. Images you copy or save as PNG are flat, so blurs and crops cannot be undone by whoever receives them.
