What you can contact us about

You can report a technical error, comment on your experience, make a data request, report a security issue, or suggest a new PDF tool. Include steps to reproduce the issue with a sample file that contains no sensitive information.

• Problems with uploads, job status, processing, or result downloads.
• Unexpected conversion, OCR, compression, organization, or protection results.
• Questions about anonymous sessions, cookies, the one-hour expiration period, or cleanup every five minutes.
• Reports about signed links, access control, or behavior that may indicate a security incident.
• Feedback on instructions and suggestions for new PDF tools.

Information that helps us handle a request

A report should include the tool name, page URL, approximate time, browser, operating system, file size and type, selected options, error code, and each step needed to reproduce the issue. If an example is needed, create a minimal sample file with no personal or confidential data.

Do not send session cookies, PDF passwords, private keys, digital certificates, screenshots containing sensitive data, or active upload and download URLs. Jobs belong to anonymous sessions and access expires after one hour, so an error code and time are usually more useful than the real document.

Security and privacy reports

For a security issue, describe the impact, conditions, and safe reproduction steps. Do not access another person's job, disrupt the queue, or exploit an issue beyond what is needed to demonstrate it. If you believe a signed link has been exposed, delete the job through the interface while you still have access.

For a privacy question, state which tool you used and the type of request. The current tools do not require an account. A signed HttpOnly cookie identifies the anonymous session. Files are processed on the server, access expires after one hour, and cleanup runs every five minutes.

What to expect

Each request is assessed by impact, reproducibility, and the service's support scope. We may ask for more details or ask you to try again with a sample file. The service has no fixed response time, 24/7 emergency support, or guarantee that every file can be recovered or produce the expected result.

Support is not a substitute for legal advice, a compliance assessment, digital forensics, or organization-specific security advice. Support conversations are limited to explaining and resolving problems with Tools.4PDF.Net within the service's technical scope.

Before you email

Keep the original, download any required result before the job expires, and read the instructions on the tool page. If the result has an error, confirm that the source file opens normally and meets the format limits. This information helps determine whether the problem is in the input or processing without sending the real document.
