Temporary File Storage

At JPDFConvert, we understand that your documents are often sensitive, private, or even legally protected. That’s why we’ve built our entire system around the principle of local file processing and temporary memory usage. When you upload a document to JPDFConvert, that file never leaves your browser.

1. Local Processing by Design
Unlike traditional online tools that send your documents to external servers for processing, JPDFConvert performs all operations using in-browser JavaScript. This means that your document is never transmitted over the internet—it remains within your device’s memory at all times. No servers, no third parties, no storage. The conversion happens instantly, and once completed, the file is released from memory.

2. No Persistent Storage
We do not maintain user sessions, databases, or file logs. When you close your browser tab or refresh the page, all traces of your file are gone. Temporary memory (RAM) is used for the process, and nothing is stored on disk. This ensures full control over your data—there’s nothing for us to lose, leak, or misuse.

3. Secure Browser APIs
To handle files securely in memory, JPDFConvert uses modern web APIs such as FileReader, Blob, and ArrayBuffer, which are trusted and maintained by browser vendors. We follow security best practices by avoiding deprecated APIs and minimizing access to system-level resources. The result is a fast, lightweight, and secure environment for document conversion.

4. Why It Matters
Users often ask why JPDFConvert doesn’t offer file history or saved conversions. The answer is simple: by not storing anything, we remove the risk of breach. Even in the event of a browser vulnerability, your files are never exposed to an external network or saved state.

JPDFConvert’s storage philosophy is grounded in transparency. We’re not just saying we care about your privacy—we’ve engineered our platform so that we never have access to your data in the first place.

5. How Temporary Memory Works

In a browser-based application like JPDFConvert, file data is loaded into RAM as a temporary binary object. This binary data resides only in volatile memory, which means that it is automatically cleared when the browser tab is closed, the page is refreshed, or the allocated memory is released. Unlike files saved to your local disk, these temporary objects do not persist beyond the active browser session.

6. The Role of the Garbage Collector

Modern browsers use a garbage collection mechanism to manage memory. When JPDFConvert finishes processing your file and no longer holds a reference to its data, the garbage collector marks that memory as eligible for release. This ensures that your file is effectively erased from active memory without requiring manual deletion steps.

7. Why No Server Backup Is a Feature

Many users are accustomed to cloud-based services that automatically back up every uploaded file. While convenient, this also introduces long-term privacy risks—your data remains in someone else’s storage, potentially accessible to unauthorized parties or vulnerable to breaches. By design, JPDFConvert avoids this problem entirely: if you want a backup, you create it yourself on your device, and you control where it resides.

8. Zero-Knowledge Proof in Practice

In data security terms, JPDFConvert functions with a "zero-knowledge" approach. Because we never receive or store your file data, we have no knowledge of its contents. This is not merely a policy promise—it is an architectural reality that eliminates whole categories of data exposure risk.

9. Recommended User Practices

• Store converted PDFs in a secure, encrypted location on your device.
• Use password-protection features in your PDF viewer or editor for sensitive documents.
• Clear your browser's cache and temporary files periodically, especially on shared devices.
• Consider running JPDFConvert in a private/incognito window for added assurance.

10. Example: Sensitive Legal Document Conversion

Imagine a law firm needing to convert confidential case files into PDFs. With JPDFConvert, the files never leave the firm’s own computer network. This eliminates the risk of violating legal confidentiality rules or exposing case materials to unintended recipients. In scenarios where professional ethics and compliance are critical, local-only processing provides a decisive advantage.

11. Compliance-Friendly by Default

Regulations like GDPR, HIPAA, and CCPA place strict rules on personal data handling. Because JPDFConvert does not store or transmit files, it inherently aligns with many of these requirements without complex data-processing agreements. For enterprises, this reduces compliance overhead and minimizes the scope of data-protection audits.

12. Incident Containment

In the unlikely event that our website were compromised, the absence of stored user files means there is nothing for attackers to steal. This drastically limits the potential damage of any breach and ensures that your data remains unaffected even during security incidents.

13. Technical Safeguards Beyond Storage

• All scripts are loaded over HTTPS to prevent interception or tampering.
• No cross-origin requests are made for file contents.
• Processing logic is sandboxed within the browser to isolate file operations from other site components.

14. Transparency in Implementation

We openly describe our storage model because it is fundamental to our trust relationship with users. Anyone with basic web development skills can inspect our client-side code to confirm that no file-upload logic exists. This transparency allows informed users to verify our claims independently.

15. Closing Thoughts

Temporary file storage isn't just a feature—it's a philosophy. It reflects a conscious choice to prioritize your privacy and security over convenience features that could compromise your trust. By keeping everything local and transient, JPDFConvert delivers a level of safety that server-dependent tools simply cannot match.
