Privacy & security

JoinMyPDF is designed around local processing: merge, split, compress, and common conversions run in your browser session. Your files are not sent to JoinMyPDF servers to execute those operations.

Downloads are generated on-device. Standard outputs from these tools are not watermarked by JoinMyPDF.

Limits still apply: browser memory, device performance, and PDF protections (passwords, restrictions) can block some tasks. Very large files may fail on low-memory devices— split first, then process in batches.

Analytics may collect usage signals (for example PostHog) to understand which tools help users succeed. Configure an ad/analytics blocker if your policy requires it.
