Workflow Builder Never Uploaded
Chain rotate, watermark, and page numbers into one reusable pipeline โ runs entirely in your browser.
Pipeline
What is the Workflow Builder?
Instead of opening three separate tools, build one pipeline and run your PDF through it in a single pass. The MVP supports three steps โ rotate, watermark, and page numbers โ chained in the order you arrange them. Everything runs locally in your browser with pdf-lib; your file never leaves the device.
- Rotate: turn every page 90°, 180°, or 270°.
- Watermark: stamp diagonal or flat text on each page with adjustable size and opacity.
- Page numbers: add
{n}or{n} of {total}in the corner of your choice. - Save & reuse: name a workflow and reload it later โ definitions are stored in your browser (server sync is planned).

Frequently asked questions
Is my file uploaded?

Is it free?
Yes, completely free with no signup and no watermark added by us.
What steps are supported?
The MVP supports three steps: rotate, add watermark, and add page numbers. More steps are planned.
Can I reorder steps?
Yes โ drag a step left or right within the pipeline to change the order it runs in.
