Privacy and security
iChoosePDF is built around browser-first PDF processing. When a tool can complete a task locally, the document stays on your device and does not need to be uploaded just to finish the job.
For sensitive files, review the output before sharing, use strong passwords where appropriate, and keep an original copy of important documents.
