Section 01

General Information

FormatOS provides browser-based file conversion tools for informational, utility, and convenience purposes. The website is designed to help users convert files between supported formats quickly and easily, with the current public tools running in your browser on your own device.

The tools, information, and services provided on FormatOS are offered in good faith. However, the website does not guarantee that every file type, format combination, device, browser, operating system, use case, or workflow will work perfectly or produce the exact results you expect.

The service is a general-purpose file conversion utility. It is not a professional file processing pipeline, a certified data management system, a compliance tool, or a substitute for purpose-built professional software. The content and tools on this site may contain errors, omissions, technical limitations, or inaccuracies.

Users are responsible for determining whether FormatOS is appropriate for their specific files, needs, professional context, and legal obligations before relying on it.

Section 02

File Conversion Accuracy

File conversion is a technical process and may not always produce exact, complete, or perfect results. FormatOS aims to provide useful output but does not guarantee that conversion results will accurately match the original file in every case.

Output quality may vary depending on factors including — but not limited to — the source file's quality and structure, format limitations, file size, compression settings, font availability, embedded content, file encoding, metadata, file corruption, browser compatibility, device performance, conversion engine capabilities, and software or technical constraints inherent to converting between particular formats.

The following elements may change, degrade, be partially or fully lost, or behave differently in a converted file:

  • Page layout and formatting
  • Colors and visual styling
  • Fonts and typography
  • Image and photo quality
  • Transparency and alpha channels
  • Layers and design elements
  • Document structure and hierarchy
  • Tables, grids, and spreadsheet data
  • Extracted text and recognized (OCR) text
  • Data field structure (CSV, JSON, XML, YAML)
  • Embedded content and objects
  • File metadata and properties
  • Bookmarks, outlines, and links
  • Interactive and dynamic elements

Some files may fail to convert entirely due to corruption, password protection, unsupported encoding, unusual structure, or file size. Some converted outputs may not open correctly in all applications, operating systems, or devices.

You should always carefully review converted files before relying on them for any professional, legal, financial, academic, creative, official, or business purpose. FormatOS is not responsible for inaccurate, incomplete, failed, delayed, corrupted, incompatible, or unexpected conversion results.

Section 03

File Backups

You should always keep a backup copy of your original file before using FormatOS to convert it. This is a basic precaution that applies to any tool, and it is especially important when working with files that cannot be easily recreated.

FormatOS is a file conversion tool, not a cloud storage service, backup system, document archive, or permanent file hosting platform. The current public tools run entirely in your browser on your own device, and your files are not uploaded to or stored on FormatOS servers. Converted outputs exist only in your browser session and may be lost if you close or refresh the page, navigate away, or experience a browser, device, or technical interruption.

You are responsible for saving, downloading, verifying, and securely storing your own original files and converted outputs. You should download and verify your converted file as soon as it is available and not assume that it will remain accessible after you leave the page.

FormatOS is not responsible for lost, deleted, corrupted, expired, unavailable, damaged, overwritten, or otherwise unrecoverable files or conversion results, regardless of the circumstances.

Always back up first. Before converting any file, save a copy to your own device or storage. Do not use FormatOS as your only copy of any file.

Section 04

Uploaded Files and User Responsibility

You are solely responsible for the files you select, convert, download, store, share, or otherwise interact with through FormatOS. Because the current public tools run in your browser, FormatOS does not review, verify, approve, or endorse the files you process with the service.

You must ensure that you have the legal right, permission, licence, or authority to upload and convert any file you submit. You must not upload files that are illegal, harmful, abusive, copyrighted without permission, private, confidential, restricted, or sensitive unless you understand and accept all applicable risks and have the legal right to process that material online.

FormatOS may reject, block, limit, rate-limit, or remove files or activity that appears unsafe, unsupported, abusive, illegal, suspicious, technically incompatible, or potentially harmful to the service or other users. This may occur without prior notice.

You remain responsible at all times for complying with copyright, privacy, data protection, intellectual property, and all other applicable laws in relation to any file you upload or convert through this service.

Sensitive files: You should avoid uploading highly sensitive, confidential, regulated, private, financial, medical, legal, government, business-critical, or legally restricted information unless you fully understand and accept the risks of processing such material with a browser-based conversion tool on your own device.

Section 06

No Professional Advice

FormatOS provides file conversion tools and general website content only. Nothing on this website — including its tools, results, content, descriptions, or documentation — constitutes or should be considered legal, technical, compliance, financial, medical, tax, business, security, regulatory, or professional advice of any kind.

For files or situations that involve legal rights, regulatory compliance obligations, professional responsibilities, regulated data categories, business-critical decisions, copyright determination, sensitive personal data, medical records, financial records, or other matters where professional judgment is required, you should consult a qualified professional before proceeding.

You are solely responsible for evaluating your own risk, legal situation, professional obligations, and compliance requirements before using FormatOS for any particular file or purpose. FormatOS is a convenience tool and should be used accordingly.

Section 07

Security

FormatOS aims to apply reasonable technical and operational measures to operate the service safely and to protect against common security threats. The current public tools process your files entirely in your browser on your own device, and your files are not uploaded to or stored on FormatOS servers. However, no website, browser process, device, or computing environment can be guaranteed to be completely secure.

You should not process files you are not comfortable working with on your own device. If a file contains highly sensitive, confidential, regulated, or personal information, you should consider whether a browser-based conversion tool is the right choice for that specific file.

You are responsible for the security of your own devices, browsers, networks, and files before you process them with the service. You should not open files from unknown or untrusted sources, and you should scan files for malware or harmful content on your own device before working with them.

FormatOS is not responsible for security issues caused by user devices, user networks, browser extensions, compromised files, malicious content, third-party services, or circumstances outside reasonable control.

Section 08

Service Availability

FormatOS does not guarantee uninterrupted, permanent, unlimited, error-free, or always-available service. The website and its conversion tools may be updated, interrupted, limited, suspended, delayed, unavailable, or discontinued at any time with or without prior notice.

Specific file formats, conversion tools, or output options may be added, changed, limited, removed, or made temporarily unavailable as the service evolves. The list of supported formats and the quality of conversion outcomes may change over time.

Whether a particular conversion succeeds may depend on browser compatibility, file size, file type, file encoding, available device memory, device performance, and technical constraints at the time of use. Large files may be slow or may not complete on lower-powered devices.

FormatOS may apply rate limits, file size restrictions, processing limits, download limits, conversion frequency restrictions, or abuse-prevention controls to maintain a fair and reliable service for all users.

Section 09

Third-Party Services

FormatOS may rely on or integrate third-party services to operate the website. The current public conversion tools run in your browser and do not send your files to a third-party conversion service. The third-party services that support the site may include:

  • Web hosting and content delivery for the website
  • Analytics and usage monitoring
  • Security, threat detection, and bot protection
  • Open-source libraries that run in your browser to perform conversions
  • Advertising and ad measurement partners
  • Contact form and email handling
  • Content delivery and caching
  • Browser or device-level processing capabilities

Third-party services operate under their own terms, privacy policies, security practices, technical limitations, and data handling standards. FormatOS does not control all aspects of third-party services and is not responsible for third-party errors, interruptions, data practices, content, claims, products, services, or any damages arising from their use.

You should review the terms and privacy policies of third-party services before relying on them, particularly where those services may process personal information, files, or usage data.

Section 10

Advertising

FormatOS may display advertisements through third-party advertising partners or advertising networks. Advertising supports the operation, maintenance, and improvement of the website and its file conversion tools.

Third-party advertising partners may use cookies, pixels, device identifiers, or similar technologies to serve, personalize, measure, and improve advertisements. These partners collect and use data in accordance with their own privacy policies and applicable advertising standards.

FormatOS does not personally control every advertisement, product claim, destination link, offer, service, or content shown through third-party advertising systems. The appearance of an advertisement on FormatOS does not constitute an endorsement by FormatOS of the advertiser, their products, services, claims, pricing, or website.

You should independently review any advertised product, service, website, privacy policy, and terms before interacting with them. Displaying advertising does not mean FormatOS sells your files or documents to advertisers. With the current public tools, your files are processed in your browser and are not uploaded to FormatOS servers, so they are not shared with advertising partners.

Section 12

Limitation of Liability

To the maximum extent permitted by applicable law, FormatOS and its operators are not liable for any damages of any kind arising from your use of — or inability to use — the service or its conversion tools, including but not limited to:

  • Failed or incomplete conversions
  • Inaccurate conversion results
  • Corrupted or damaged files
  • Lost, deleted, or unavailable files
  • Formatting or layout changes
  • Metadata or data loss
  • Image quality loss or OCR/extraction errors
  • Compatibility problems
  • Download failures
  • Temporary or extended service interruption
  • Business interruption or loss of profits
  • Device performance or technical issues
  • Security incidents beyond reasonable control
  • Third-party service errors or interruptions
  • Unauthorized use caused by user behavior
  • Indirect, incidental, or consequential damages

These limitations apply regardless of the legal theory under which a claim is made and regardless of whether FormatOS has been advised of the possibility of such damages. Some jurisdictions do not allow certain limitations on liability, so some of the above may not apply to you depending on your location.

Section 13

User Assumption of Risk

You use FormatOS at your own discretion and risk. By using the service, you accept the limitations described in this Disclaimer and the broader Terms & Conditions.

You are responsible for:

  • Deciding whether browser-based file conversion is appropriate for your specific files, use case, and professional context.
  • Reviewing every converted output carefully before relying on it.
  • Keeping original backup copies of all files before uploading or converting them.
  • Downloading and saving converted outputs promptly after they are available.
  • Complying with all applicable copyright, privacy, data protection, and other laws in connection with your use of the service.
  • Ensuring you have the rights and permissions necessary to upload and convert any file you submit.
  • Your own professional obligations, compliance requirements, and regulatory responsibilities.

Section 14

Changes to This Disclaimer

FormatOS may update this Disclaimer from time to time to reflect changes in the service, its tools, applicable laws, or operational practices. When changes are made, the "Last updated" date shown at the top of this page will be revised.

Your continued use of FormatOS after an updated Disclaimer is published constitutes your acceptance of the revised version. If you do not agree with the updated Disclaimer, you should stop using the service.

We encourage you to review this page periodically, particularly if you regularly upload files or rely on the conversion tools for professional, legal, or business purposes.
