01
On-device engines
pdf-lib, pdf.js, and pdfcpu WASM run in this tab - not on our servers.
02
No account wall
Open a tool, drop a PDF, download. No signup, trial, or watermark.
03
Honest tools
When a tool flattens pages (compress, redact), the UI says so.
Catalog
Every tool, one place
Pick what you need. Each opens a focused workspace in the sidebar app.

Close the tab.
Nothing was left on a server.
That is the entire product thesis. Tools should be powerful without turning your documents into someone else's data problem.
