Built in the open
LeedPDF is fully open source under the AGPL-3.0 license. View the code, contribute features, or adapt it for your needs.
Why open source?
We believe PDF annotation tools should be transparent, trustworthy, and community-driven.
-
Transparency
See exactly what LeedPDF does with your documents. No hidden telemetry, no mystery network requests.
-
Trust
Anyone can audit the code. No need to take our word for it: you can verify.
-
Community
Bug reports, feature ideas, and contributions make LeedPDF better for everyone.
-
Longevity
Even if we stopped maintaining it, the community could carry LeedPDF forward.
