Disclaimer

SonoFiles provides practical file utilities and explanatory information. The tools are designed to help with routine workflows, but file conversion is not always exact and the service should not be treated as a professional certification or verification system.

Always review important output

A file that downloads successfully can still contain a layout, font, image, formula, page-size or text-extraction difference. Review the complete output before sending it to a client, government agency, school, employer or other recipient. Keep the original until you have confirmed the result.

Complex documents

Office documents, PDFs and presentations can contain features that do not map cleanly between formats. Embedded fonts, macros, charts, grouped objects, comments, tracked changes, forms, unusual page boxes and proprietary features can be simplified or omitted depending on the tool and browser technology.

OCR and extracted data

Optical character recognition and table extraction can make mistakes. Names, totals, decimal separators, dates and identifiers deserve particular attention. Do not rely on extracted text or spreadsheet data without checking it against the source when accuracy matters.

Signatures and document security

A visual signature placed on a PDF is not automatically the same as a cryptographic digital signature backed by a certificate, identity verification or a regulated e-signature platform. Legal effect depends on context and jurisdiction. Password and unlock tools should only be used on documents you are authorized to access or modify.

Redaction

Redaction requires special care because simply drawing a dark shape over text can leave the underlying information recoverable. Use the instructions and verification steps provided by the specific redaction tool, and independently check sensitive documents before distribution.

Privacy and security

When a tool says processing is local, it is designed to process selected file content in the browser rather than upload it to a SonoFiles conversion server. This reduces unnecessary transfer but does not eliminate every security consideration. Your device, browser, extensions, network and downloaded files remain part of the security environment.

No professional advice

Information on SonoFiles is general technical guidance. It is not legal, financial, medical, tax, regulatory or records-management advice. Requirements for official submissions can differ between organizations and countries, so check the receiving authority's current rules when necessary.

External compatibility

Mention of a file format, browser, operating system or third-party application describes compatibility or a workflow; it does not imply sponsorship or endorsement unless explicitly stated.

Report a problem

If a tool produces a repeatable error, contact support@sonofiles.com with the tool name, browser and a non-sensitive description of the issue.
