Edit PDF
Stamp an image or text over your PDF in seconds. Choose typography and position. It runs in your browser (your file never leaves your device) and lives inside Atlas, so the result connects to the rest of your work.
Step by step
Launch Watermark inside Atlas PDF Studio: it runs right in your browser, no install and no account needed to start.
Drag and drop your PDF onto the page, or browse to pick it. Your file is processed on your device: it is never uploaded to a third-party server.
Set the options for watermark (order, range, quality, or layout) and preview the result instantly.
Save the finished PDF to your device in one click. Keep going in Atlas to file it against a task, project, or client record.
Why Atlas
Most online PDF tools are throwaway. This one lives inside the workspace where the rest of your work already is.
Watermark runs in your browser. Your document stays on your device: nothing is uploaded to a third-party server, so even sensitive files are safe.
Works on any modern browser (Chrome, Safari, Edge, Firefox) on desktop or mobile. Start instantly; create a free Atlas account only when you want to save your work.
Unlike a one-off converter, this tool lives inside Atlas: so a finished PDF can become a task, attach to a deal, or get sent for e-signature without leaving the app.
