Protect PDF tips

Keep a copy of the original input when comparing results, especially for DNS, web, image, PDF, text, and code tools. If a result depends on live network data, remember that DNS records, HTTP headers, certificates, rankings, and third-party responses can change over time.

Secure your documents with password protection. Works on all devices, no downloads, fully encrypted for privacy

This Laravel implementation uses local FPDI protection support and does not send uploaded PDFs to a third-party API. It supports standard, non-encrypted PDF files and compatibility-focused RC4 PDF protection. For stronger AES encryption, qpdf or a dedicated PDF security service should be added later.
