Contact Center, Technical Support & Official Inquiries
Welcome to the official support and communication hub for PDFListo.org. Our mission is to provide an entirely sovereign, free, and local-first document utility suite operating directly within your web browser's RAM memory. Whether you have technical questions regarding our WebAssembly engines, wish to report a browser rendering incompatibility, or need assistance regarding corporate compliance, our engineering team is at your disposal.
Technical Support & Bugs
For reporting conversion glitches, page display issues, or complex vector PDF handling problems.
contacto@pdflisto.org →Privacy & Compliance
Inquiries regarding zero-server cryptographic audits, GDPR compliance, HIPAA guidelines, or zero-retention architecture.
contacto@pdflisto.org →Feedback & Partnerships
Proposals for introducing new tools, supporting niche file formats, or academic integrations.
contacto@pdflisto.org →Service Level Agreement (SLA) & Response Times
We commit to answering every incoming user inquiry within 24 to 48 business hours. Because PDFListo operates with a strict Zero-Knowledge architecture and executes 100% inside your client browser RAM, please keep the following security guidelines in mind when contacting our team:
- Never send confidential documents via email: Our technical team will never ask you to attach private contracts, medical filings, bank statements, or confidential PDFs to diagnose a bug. User privacy is strictly non-negotiable.
- Provide technical environment details: To expedite diagnosis, please mention your browser (Chrome, Firefox, Safari, Edge), operating system (Windows, macOS, Linux, iOS, Android), and approximate document page count.
- Browser Console Logs: If your browser developer console (F12) displays any red warning or runtime error, including a text snippet helps us diagnose the root cause immediately.

Support FAQs
Why can't technical support retrieve a file I processed yesterday?
Because PDFListo is an uncompromisingly client-side web application. We operate zero cloud document databases and zero remote file caches. As soon as you close or reload your browser tab, your file data vanishes from memory RAM without leaving any trace on the web.
Are there any fees for using tools or requesting assistance?
No. All tools on PDFListo are provided 100% free of charge with zero usage caps, supported by unobtrusive and policy-compliant display advertising.
Where is the project developed and maintained?
PDFListo.org was conceived and engineered in Buenos Aires, Argentina, by software engineer Darío Torralbo, operating as an open, privacy-centric utility platform for users worldwide.
Technical Service Level Agreement (SLA) & Inquiry Matrix
PDFListo performs low-level binary manipulation and vector assembly directly inside your host browser via WebAssembly. If you encounter rendering anomalies or processing interruptions with massive files, review our structured service channels:
Critical Processing Incompatibilities: Target response time < 24 business hours. Primary channel: contacto@pdflisto.org with subject line [TECHNICAL ISSUE].
Privacy Inquiries & Regulatory Audits: Target response time < 48 business hours. Formal clarification regarding GDPR, CCPA, zero-retention architecture, and memory sanitation.
Institutional Partnerships & Academic Inquiries: Educational licensing, API architecture questions, and media inquiries.
Enterprise Deployment & Corporate Firewall Guidelines
Healthcare organizations, legal firms, and government agencies operating under strict network perimeters can safely deploy PDFListo without administrative friction. Because our suite operates exclusively on static assets via HTTPS, it introduces zero cloud security liabilities:
- Pure Static Delivery: The domain serves exclusively static HTML, CSS, JS, and compiled WASM assets. No outbound POST requests containing document payloads are ever initiated.
- Enterprise Browser Compatibility: Fully compatible with Chrome Enterprise, Edge for Business, and Firefox ESR under standard group policies (GPO).
- Transparent Network Auditing: Network security engineers can independently verify zero egress by inspecting browser DevTools Network telemetry during high-volume document batch executions.
Browser Diagnostic Protocol & WebAssembly Troubleshooting
PDFListo performs low-level binary manipulation and vector assembly directly inside your host browser via WebAssembly. If you encounter rendering anomalies or processing interruptions with massive files, review the following hardware and software considerations before opening an official support ticket:
- Hardware Acceleration & WebAssembly Runtime: Ensure your browser has hardware graphics acceleration enabled and WebAssembly execution active. All modern versions of Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge support these runtime capabilities out of the box.
- Browser Heap Memory Allocations: 32-bit browsers and constrained mobile devices enforce strict virtual memory allocation ceilings (typically 1.5 GB to 2 GB per browser tab). When operating on files exceeding 250 MB, we recommend utilizing a 64-bit desktop operating system to prevent tab memory termination.
- Content Security Policies & Script Shielding: If your environment operates behind corporate firewalls or aggressive script-blocking extensions, ensure that local WebAssembly binary assets (.wasm) and standard font glyph tables are not intercepted.
Extended Technical FAQ & Enterprise Support Policies
Can PDFListo be embedded in our internal intranet or corporate portal?
Yes. Because PDFListo requires zero backend database infrastructure and transmits zero network payloads, organizations can whitelist our domain or deploy the Progressive Web App (PWA) client across corporate workstations without creating external security vectors.
How does technical support assist with font rendering anomalies?
If non-standard TrueType, OpenType, or Type 1 fonts appear distorted during conversion, you can report the font family and encoding scheme to our engineering team. We continuously update our WebAssembly glyph parsing tables to expand international font subset compatibility.
What is our formal stance on user data retention during support tickets?
We enforce a zero-storage principle across all support interactions. We request that users anonymize or substitute dummy text into sample files before sharing test cases, guaranteeing that real consumer or corporate data is never transmitted via email.
Data Sovereignty & Local Cryptographic Guarantees
PDFListo adheres to strict cryptographic data sovereignty protocols. We maintain an open architecture where every byte manipulation can be traced directly to compiled WebAssembly client modules without obfuscated external dependencies. When consulting our technical desk regarding specialized regulatory environments (such as HIPAA in healthcare or CJIS in criminal justice), our engineering staff can provide formal architectural attestation documentation confirming zero third-party cloud data transit.
