How it works

Complete the job in three clear steps

  1. Add a PDF, page, mark type, and position.
  2. Choose the relevant options and create an annotated PDF.
  3. Review the result, then copy or download it when available.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Questions

About this tool

Does this tool upload my working data?

No. The workspace processes its input in this browser and does not send the working content to Lucaden.

Should I verify the result?

Yes. Keep important originals and check generated files, codes, calculations, and transformed data in the system where you plan to use them.
